The TALOS ensemble is a new initiative in USSOCOM that is intended to provide solutions for the enhanced mobility/protection/situational awareness capabilities to augment the direct assaulter. As such, the power supply for the TALOS ensemble will need to provide sufficient, dependable power to ensure rapid, unencumbered movement of the operator. Desired attributes of the power system also include light weight, low noise, and low to no thermal signature. Power sources should not require introduction of a new logistics fuel to the battlefield. The power source shall produce 4-5kW of power continuously for a non-tethered 12 hour mission. The system shall be compatible with shore power (i.e. helicopter power, ship power, Forward Operating Base grid power, indigenous power infrastructure in the operational area). The power supply shall be able to utilize extraction platforms (e.g., helicopters and small craft) power to commence immediate system recharge. The power supply shall be able to scavenge power from sources found on a battlefield (i.e. power lines, car batteries, solar, 110/220VAC power outlets, etc.). The power supply shall be rechargeable and ready for the next mission within 6 hours. The size of the power source shall not exceed 15 x 10 x 5. The weight of the power source shall not exceed 15 pounds. The power source shall be nonflammable. A secondary objective of this effort is to enable Special Operations Forces wearing exoskeleton type equipment to more easily carry the weight normally carried by an operator while hiking over long distances.

CRG's no-oven, no-autoclave (NONA) cure of OoA or autoclave prepreg materials allows the manufacture of large composite structures without the expensive and energy-intensive capital equipment currently required for fabrication. Qualified autoclave or OoA prepreg tapes can be applied simultaneously with dry unidirectional (UD) tapes in an automated process. The presence of dry fibers throughout the layup before infusion allows improved breathing, removal of volatiles from prepreg, and improved compaction with only atmospheric pressure, mimicking the double vacuum debulk (DVD) process without the equipment. NONA resin is then introduced at ambient temperature to wet out all available contact surfaces and cure itself and the prepreg. The NONA epoxy resin uses its own chemical energy to propel itself through a complete cure with no external heat required. The baseline NONA resin provides good strength, chemical resistance, and thermal performance up to 350F. Pairing NONA resin with a compatible prepreg a cure of both systems is achieved at room temperature. Because the cure occurs at room temperature, the NONA resin locks in its shape near room temperature, thus allowing the use of low-cost tooling materials, typically avoided because of high CTE.

This project will combine the advantages of adaptive materials with the simplistic passive design of state-of-the-art acoustic liners to provide the ability to tune them for specific operational frequencies (ex. take-off/cutback, cruise, and approach). Many proposed solutions are not practical from a manufacturing/cost perspective: too complex or add weight to the aircraft that is not justifiable. The requirements for aircraft noise are becoming more stringent with greater emphasis on improvements in performance efficiency and lower fuel consumption. CRG has demonstrated feasibility in implementing adaptive technologies into acoustic liners. The next step is to develop increased understanding at more relevant size scales to demonstrate repeatable liner control performance supported by more extensive acoustic testing runs to understand the initial shifting and increased suppression behaviors that have been observed. Automated cyclic testing of a given adaptive liner parameter will be executed on the order of hundreds of thousands of times to demonstrate the durability of the adaptive material for this application. CRG has focused adaptive liner design on demonstration of tuning reactance to TRL 3-4 in Phase I. CRG will develop multiple integrated prototype demonstrators with flow duct testing to achieve a TRL 5-6 at the end of Phase II.

ABSTRACT: Researchers are identifying new biomarkers to help monitor, diagnose, and treat growing threats to the human body and enhance human performance. Recent sensor work combining biorecognition elements with field effect transistors (bio-FETs) has been shown sensitive and selective to biomarkers in the picomolar range with continuous detection; however device-to-device performance variability, reliability, and scaled manufacturing remain a challenge. For practical applications, device variability should be less than 10% for a reliable sensor in practical applications. Materials used in fabrication of bio-FET platforms also need to be cost effective and scalable for mass production. CRG proposes a water stable organic FET (OFET) based biosensor. In Phase I CRG demonstrated a base OFET platform from scalable solution processable materials that can achieved less than 10% variability in device performance. This base OFET platform could be functionalized with different materials that allow the conjugation of a variety of biorecognition elements. CRG demonstrated the platform in multiple sensor applications including a biosensor. The base OFET platform also has the potential for compatibility printed electronics manufacturing processes. In Phase II CRG will optimize the platform for a specific biomarker and scale device production to achieve a reliable and reproducible biomarker sensor for practical applications.; BENEFIT: Operational Benefits: (1) Extremely low detection limits (picomolar) (2) Water stable (3) Scalable materials for flexible printed electronics (4) Reliable and low variability device performance (5) Long term stability and continuous detection Commercial Applications: (1) Environmental monitoring (2) Multiplex healthcare diagnostics (3) Point of care diagnostics

While much attention is necessarily focused on the evaluation and certification of the materials and processes involved in adhesive bonding, development is still needed in decreasing the cost, time, and complexity of the current repair concepts. A material and processing system is needed that allows the design, infusion, and cure of composite repairs without the current roadblocks imposed by ovens, autoclaves, and expensive tooling. VARTM processing of custom repairs allows freedom in design and minimizes the specialized tooling required for patches and straps that are prefabricated apart from the structures needing repair. CRG's no-oven, no-autoclave (NONA) composite processing technology enables the fabrication of high-performance composite parts without the limitations imposed by autoclaves and ovens. NASA originally funded CRG to develop the materials and processes for the manufacture of large, single-piece space launch structures. Building on that activity, CRG proposes NONA repair of composite structures. In this concept, NONA resin is introduced to a scarfed surface and dry fiber via VARTM processing and undergoes complete cure without additional heat input. NONA offers the opportunity to repair PMC structures on-site without the use of large capital equipment. The University of Dayton Research Institute will conduct the scarfing and evaluation of test materials. The resin consists of common aerospace epoxy components, but it is formulated to achieve complete cure in a matter of hours without additional heat input. The two-part epoxy system uses its own chemical energy to propel itself through a complete cure. It provides good strength, chemical resistance, and thermal performance up to 350 deg. F. CRG envisions a mobile fleet of NONA composite technicians that can perform repair activities at manufacturing sites around the world, restoring functionality to damaged structures and tools, minimizing impact on plant operations and production.

Cornerstone Research Group Inc. (CRG) proposes to continue efforts from the 2015 NASA SBIR Phase I topic H14.03 ?Reversible Copolymer Materials for FDM 3D Printing of Non-Standard Plastics.? CRGs offers NASA the ability to reprocess space mission waste packaging plastics as an In-Situ resource for in space manufacturing via Fused Deposition Modeling (FDM) type 3-D printing of replacement tools, parts, and devices. This innovation is enabling for space exploration, the application of CRG?s reversible thermoset (RVT) polymers combined with a plastic recycling, blending, and extrusion process will allow current and future packaging materials to be processed into a copolymer blend filament suited to FDM 3-D printing system. This approach offers two implementation routes including; (1) An RVT additive that can be combined with existing waste packaging during a reclamation process to produce 3-D printer filament and (2) A RVT based replacement packaging material that can be directly reclaimed into 3-D printer filament. The material properties of 3-D printer filament from the RVT-based reclamation process can be tuned for mechanical performance (stiffness, flexibility) by adjusting the blend ratios of reclaimed waste packaging:RVT. This will provide NASA with a means to generate 3-D printer feedstocks with varying mechanical performance from on-hand packaging plastics without the need for separate 3-D printer material payloads. CRG has already demonstrated the efficacy of RVT additive in reclamation of NASA?s packaging materials in Phase I by producing a co-polymer blend of RVT with NASA packaging, producing a FDM printer filament with the reclaimed packaging, and successfully 3-D printing the resulting reclaimed packaging material. CRG?s proposed approach to further develop thermally-reversible polymer materials to reclaim NASA?s packaging will provide a material and processing technology readiness level (TRL) of 5 at the conclusion of the Phase II effort.

Cornerstone Research Group Inc. (CRG) proposes to design and develop thermally-reversible polymeric materials that will function as reprocessable thermosetting matrixes. These material systems will enable reclamation and repurposing of structural fiber-reinforced composites into new configurations during extraterrestrial missions, such as conversion to Additive Manufacturing (AM) feedstocks or direct fabrication into multipart constructs. The thermally-reversible polymer thermosets also present the opportunity to generate volumes of AM feedstock through function as an optimized binder matrix, allowing compounding and impregnation/infusion of in-situ resources such as environmentally sourced metallic, mineralogical (i.e. regolith), and desized/milled non-reprocessable composites. This material approach will provide NASA with a means to generate AM feedstock and support in-situ resource utilization with a reduced reliance on pristine raw material payloads. CRG has already demonstrated the efficacy of thermally-reversible polymer structures in commercial adhesive applications, as well as in a previous NASA technical effort for modifying waste packaging plastics to provide improved compatibility to AM processing (specifically FDM). The proposed concept not only has the potential to enable resource reclamation and AM capability, but also to advance the state-of-the-art in AM materials technology. CRG's proposed approach to develop thermally-reversible polymer materials for thermoset polymer reprocessing, and demonstration of reclamation and AM compatibility evaluation, will provide NASA with a material and processing technology readiness level (TRL) of 3 at the conclusion of the Phase I effort.

CRG proposes to advance the solar sail boom system with a bi-stable, deployable, composite boom which implements a composite electrically activated shape memory polymer (EASMP) to transition the matrix with characteristics representing an elastomer, for storage and deployment, into a thermoset creating a rigid boom. This bi-stable solution will allow for a lightweight, reliable, and controlled solution of deployment while consuming less power upon deployment compared to current metal booms. This technology will not be limited by mission; it is scalable for larger solar sails in future missions and missions with similar applications such as the Lunar Flashlight.
