Recent exciting technical advances have meant that composite materials are better equipped than ever to meet current and future challenges in deep-water and remote-area piping environments. Indeed, composites have become hugely popular materials for stateof-the-art piping systems, whether in spoolable monolithic flowlines, armour reinforcements in flexible pipes, composite-lined pipes, rigid risers or other applications. © 2015 Ashland AD-13070.

A strain-life fatigue database for cast irons was developed utilizing American Foundry Society (AFS) and the United States Department of Energy (DOE)funding. The database contains monotonic and cyclic property data, as well as the associated chemical analysis and microstructural data for a variety of cast irons, including gray, ductile, compacted graphite, and white cast irons. This paper first reviews the contents and format of the database. The database and its associated report contain no comparative analysis of any of the cast iron grades. The fresh approach of this paper is to analyze and compare the data across each section size and strength-ductility combination for four ductile iron grades. i.e.. ferritic 60-40-18. ferritic-pearlitic 65-45-12, pearlitic 100-70-03 and tempered martensitic (Q&T) 120-90-02. The ductile cast iron results in the database generally exhibited the expected trends. Modulus and Poisson's ratio were the same for all the conditions. Monotonic strength always decreased with increasing elongation and ferrite content. The higher strength grades and conditions exhibited greater high cycle fatigue resistance and decreased low cycle fatigue resistance. Heat treatments had a mixed effect on monotonic properties. Annealing decreased the monotonic strength of 60-40-18 whereas normalizing increased the strength and dramatically increasedfatigue resistance ofpearlitic 100-70-03. Monotonic ductility was only slightly affected by heat treatment. However, in most conditiüns, the heat treatments produced greater low cycle fatigue lives for high ductility conditions. Althüugh the high cycle fatigue resistance was affected less by heat treatment, slightly increased high cycle fatigue lives were obtained with higher strength conditions. The normalized 25 mm samples of grade 100-70-03 exhibited sigmficantly greater monotonic strength as well as fatigue resistance in both the low and high cycle regime.

A composite aero-structure with self-repair capabilities will offer durability, extend its service life and prolong maintenance protocols leading to lower aircraft operational costs. Despite the extensive research activities in the area of self-healing resins applied to composite materials, the research for aeronautical applications is currently very limited. To this end, the main objective of HIPOCRATES is the development of self-repair composite materials by transforming widely used resins within aeronautical industry to self-healing materials, facilitating this way the subsequent certification and its related cost. Taking into account the current technological maturity of self-repair, secondary structural composites shall be targeted. The transformation will be done through the epoxy enrichment with appropriate chemical agents, following three main strategies: a) The nano-encapsulation strategy that involves incorporation of nano-encapsulated healing agents and a dispersed catalyst within a polymer matrix, b) The reversible polymers strategy where remediable polymer matrices follow the Diels-Alder chemical reaction rendering damage repairable through triggered reversible cross-linking. c) A combination for the first time of a) and b). For all strategies the current progress of nano-technology will be utilized towards either better facilitation of self-healing process (e.g. nano-carriers) or enhancement of the self-healing performance or integration of other functionalities (e.g. monitoring of the self-healing performance, activation of DA reaction). Impact, fracture and fatigue mechanical tests are envisioned to assess the self-healing efficiency. Manufacturing challenges that arise from incorporating such self-healing thermosetting systems into fibrous composites (pre-preg, infusion/RTM) shall be closely investigated at the early stages of development to ensure the effective transfer of the desired properties to the large scale as required by the industry.

The aim of CoACH (Advanced glasses, Composites And Ceramics for High growth Industries) is to offer a multidisciplinary training in the field of high-tech GLASSES, CERAMICS and COMPOSITES based on effective and proven industry-academia cooperation. Our scientific goals are to develop advanced knowledge on glass and ceramic based materials and to develop innovative, cost-competitive, and environmentally acceptable materials and processing technologies. The inter/multi-disciplinary and-sectorial characteristic is guaranteed by the presence of 5 academic partners and 10 companies having top class expertise in glass, ceramic and composite science and technology, modelling, design, characterization and commercialization. Advanced materials fall within the KEY ENABLING TECHNOLOGIES (KETs) and are themselves an emerging supra-disciplinary field; expertise on these new materials brings competitiveness in the strategic thematic areas of: HEALTH-innovative glass and composite for biomedical applications, ENERGY-innovative glass, ceramic and composite materials for energy harvesting/scavenging, solid oxide electrolysis cells and oil, gas and petrochemical industries, ICT-new glass fibre sensors embedded in smart coatings for harsh environment, ENVIRONMENT-new and low cost glass, ceramic and composite materials from waste. The originality of the research programme is to be seen in the supra-disciplinary approach to new glass- and ceramic- based materials and their applications: recruited researchers will benefit from a complete set of equipment and expertise enabling them to develop advanced knowledge in KETs and strategic thematic areas for the EU and to convert it into products for economic and social benefit. The effective research methodology used by the partners and the mutual exploitation of their complementary competences have been successfully experienced in the past in long term common research cooperation and in on-going common projects, including a Marie Curie ITN.

Element Materials Technology is to buy DNV GL’s materials testing laboratories in Germany. As a result of this agreement, Element will acquire four laboratories located across Germany, for materials testing and product qualification testing services operating in the aerospace, oil & gas, and transportation and industrials sectors.   This transaction expands Element’s current European laboratory footprint of 16 laboratories, adding to the company’s existing German laboratories located in Herne and Berlin, and takes the group’s revenues over US$300 million and number of employees to 2,000.   The DNV GL Laboratories in Germany comprise four ISO:17025/OHSAS:18001-accredited laboratories in Hamburg, Mulheim adR, Herne and Stuttgart/Esslingen, employing over seventy engineers specialized in materials testing, metallurgy and failure analysis. The laboratories have a full range of technical capabilities including destructive testing, metallography, corrosion testing, scanning electron microscopy, non-destructive testing and failure analysis which are supported by well-equipped machine shop facilities, using CNC and EDM (wire-frame) techniques for preparation of samples within a short timeframe.    ‘This significant deal is our first acquisition of a materials testing business from another large testing, inspection and certification organization,’ said Charles Noall, president and CEO of Element. ‘As our recent performance has shown, we have the financial and operational strength to make acquisitions of this scale and the expertise to integrate and immediately grow these businesses. We look forward to the future success of these locations as part of our global testing platform.’ This story uses material from Element, with editorial changes made by Materials Today.
