TIAX proposes to develop lightweight, smart composite materials capable of sensing their own mechanical and thermal state. These composites will add functionality to structural materials used both in NASA missions and high-performance commercial applications. We will build on literature methods to sense strain, damage initiation and propagation, and temperature in composite materials to prepare, in a manner consistent with production-scale manufacturing and integration into real-world systems, multifunctional composites capable of reporting on their own health. These composites will be tested to ensure that their mechanical properties meet or exceed those of the base composite and to demonstrate that the embedded sensing capability accurately reports on composite health.

Start-stop batteries offer the promise of significant improvements in vehicle fuel economy, without significant increase in vehicle sales price. A key enabling component of the start-stop system is the battery. Present start-stop systems employ lead acid batteries because of their low initial cost and excellent low-temperature performance, but these batteries suffer from life limitations especially when subjected to repeated deep cycling and high charge rates. Li-ion technology is the leading candidate to replace lead-acid batteries in start-stop systems. However, most Li-ion battery systems offered today suffer from one or more disadvantages such as poor low-temperature performance, poor high-rate charge acceptance, or high cost relative to lead acid batteries. TIAX proposes to develop Li-ion technology for start-stop applications that overcomes the limitations of the current Li-ion systems by combining its proprietary high-power cathode materials with lithium titanate LTO) anode and specially engineered electrolyte. In Phase I we will demonstrate the potential for this system to be competitive over lead acid batteries and state-of-the-art Li-ion systems for start-stop applications using cells with capacities > 200 mAh. In Phase II, the battery technology will be further optimized and performance relative to USABC targets demonstrated in a 12 V module. Widespread deployment of start-stop technology in vehicles, that can be enabled by TIAXs technology, can enhance the fuel economy of light-duty vehicles by as much as 5% without a significant increase in vehicle cost. This can allow the automobile manufacturers to meet increasingly stringent goals for fuel economy. Because start-stop batteries reduce engine idling, emissions of CO2 and pollutants such as hydrocarbons, CO, NOx and particulates can be significantly reduced in urban areas.

The Department of Homeland Security is seeking to develop a method for latent print work and DNA analysis from the same sample while optimizing DNA extraction protocol for fingerprints deposited on evidentiary materials used for human identification. Current DNA extraction protocols are highly successful at capturing DNA from prints. However, print lifting methods depend on physical alteration of the print with chemical compounds or powders that may affect DNA profiling. Our approach will be to develop a non-contact method of lifting the print that meets DHS operational requirements, and does not reduce the ability to obtain a profile from DNA extracted from the same print.

TIAX LLC is proposing to demonstrate technology for early detection of incipient internal short circuits in lithium-ion cells for three battery systems of interest to the Navy. In the Phase II Program, we will demonstrate function of two distinct short circuit detection technologies in relevant subscale battery packs, characterize design trade-offs between these technologies as a function of different types of battery pack, and demonstrate readiness for implementation in Navy systems. In the Phase II Option, and in consultation with the Navy, one of the battery systems will be selected and modified with internal short circuit detection technology designed in Phase II. The standalone battery, equipped with embedded prototype internal short circuit detection technology, will be delivered to the Navy.

In the Phase I program, TIAX LLC developed a detection methodology that was able to measure significant differences between pairs of counterfeit and authentic products in four different product categories. Establishing the proof-of-concept of this technique creates the potential for a new detection methodology that can be utilized at a port of entry by U.S. Customs and Border Protection (CBP) to identify shipments of counterfeit goods. The objective of the Phase II program is to further develop and optimize the detection methodology developed in the Phase I program. In the Phase II program, we will develop a prototype detection system and demonstrate it under field conditions in a U.S. port of entry. When fully developed, the methodology will allow for the rapid and accurate screening of closed containers for counterfeit products. It will be designed to work outdoors in a port environment in extreme weather conditions. The TIAX methodology will use instruments that are rugged, mobile and can be operated by personnel with minimal scientific training.
