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.
Boeing and Thermwood have employed additive manufacturing technology to produce a large, single-piece tool for the 777X programme. The project is demonstrating that additive manufacturing is ready to produce production quality tooling for the aerospace industry.
CRP USA will display solutions for the space industry manufactured in the Windform family of materials at Satellite Innovation 2018 at the Silicon Valley Computer History Museum, Mountain View, California, US, on 9-11 October.
Chem-Trend has been certified by the DQS (German Certification Company for Management Systems) in accordance with EN 9100:2016, fulfilling the strict quality requirements for aerospace suppliers.
