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.
According to Huntsman, the system is currently focused on investigating the influence of the composite surface structure on the peel strength of metallised CFRP epoxies, the vessels are being produced using XU 3508 / Aradur 3486, a high toughness resin system from Huntsman, processed via Resin Transfer Moulding (RTM).
Highlighting the system’s high fracture toughness, the University of Bayreuth believes it 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.
Huntsman explains that traditional materials have been replaced in pursuit of greater weight and thus composites have continued to grow within 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.
AeroNed has been appointed the authorised location for BriskHeat’s ACR hot bonder calibrations and repair in Europe. Located in the Netherlands, AeroNed will perform these services for BriskHeat’s ACR 3 Hot Bonders and ACR MiniPRO Hot Bonders.
A team of engineers at the University of Delaware (UD) is developing next-generation smart textiles by creating flexible carbon nanotube composite coatings on a wide range of fibres, including cotton, nylon and wool.
SABIC is launching its STADECK heavy-duty panel for the building and construction industry. Made from glass fibre reinforced thermoplastic resin, the lightweight panel is said to offer significant advantages across a range of applications where weight saving is important.
