JEC Group have brought together the international community of composites leaders and executives in our Composites Circle as an unique networking opportunity to meet with both peers and future partners.
Professor and Architect Mark Goulthorpe, of the MIT Department of Architecture, confirmed as guest keynote speaker for the Future of Composites in Construction.
A toughened epoxy resin system from Huntsman Advanced Materials is being used by the University of Bayreuth’s Department of Polymer Engineering, in an on-going research programme analysing the effective use of carbon fibre-reinforced polymer (CFRP) for cryogenic liquid hydrogen storage systems within aerospace applications.
Currently focused on investigating the influence of the composite surface structure on the peel strength of metallized CFRP epoxies, the vessels are being produced using XU 3508 / Aradur 3486, a high toughness resin system from Huntsman, processed via Resin Transfer Molding (RTM). Due to its high fracture toughness, the department has commented that Huntsman’s resin system is particularly well suited to cryogenic applications. Due to its chemical stability, it is also helping to optimise sandblasting pre-treatment processes on the composite surface.In replacing traditional materials in the pursuit of greater weight reduction, the use of composites continues to grow within both the aerospace and automotive industries. The use of CFRP for cryogenic liquid hydrogen storage systems is gaining increasing attention from industrial and academic parties alike. As an energy carrier, liquid hydrogen offers much higher gravimetric energy density compared to gaseous and solid stored hydrogen, as well as conventional fuel systems. Findings in the university’s recently issued article show that thanks to improvements in the adhesion of metallized coatings on composite surfaces, cryogenic storage systems traditionally made from stainless steel can effectively be produced using CFRP which has a metallic layer for permeation barrier purposes, leading to a weight reduction of approximately 60%.
