JD Lincoln has launched L-316/11, a new epoxy surface improvement film developed specifically for the manufacture of composite parts when using low pressure vacuum bag processing.
The product is designed particularly for one-shot honeycomb structures where print-through of the honeycomb structure can be a major problem.
L-316/11, which is formulated to co-cure with most epoxy systems, requires a 250°F (120°C) cure cycle, but can tolerate cycling to 350°F (180°C) and is, therefore, fully compatible with the latest generation of Out-of-Autoclave (OoA) aerospace prepreg systems.
According to JD Lincoln, L-316/11 can be applied as a surface layer to fibreglass, aramid, or carbon based laminates where it provides a tough, readily sandable, paint-ready finish. L-316/11 is flame retardant and, as part of an appropriate composite construction, is capable of meeting the requirements of FAR 25.853 (vertical burn).
As standard product, L-316/11 is supplied on a polyester veil with a total areal weight of 0.035psf (171gsm), but it can also be supplied in an unsupported format. L-316/11 is also available to order on a number of other substrates, including lightning strike mesh.
Toho Tenax is introducing a high-tensile, highly shock-resistant prepreg that incorporates carbon fibre developed for aerospace applications and carbon nanotubes (CNTs).
Thai Flight Training (TFT), a subsidiary of Thai Airways, recently ordered an Airbus A320 door trainer from Spatial Composite Solutions.
NTPT is collaborating with the Ecole polytechnique fédérale de Lausanne - Swiss Centre of Technology (EPFL) and other partners to research discontinuous fibre composite tubes for high performance applications.
