France's Nawa Technologies is doing business in the United States and introducing its fast and affordable vertical alignment carbon nanotube (VACNT) manufacturing process into a new application: making carbon fiber composites stronger.
According to Nawa, the glue between the two layers may be a weak point, which gets worse as the part is bent. This may cause delamination, or only damage the strength of the part. Nawastitch reinforced the epoxy resin layer with a super-strong VACNT array. Therefore, Nawa said that the shear strength has been increased by 100 times, the impact resistance has been increased by 10 times, delamination will not occur at all, and high-speed impact will reduce internal damage by 50%. In this way, composite parts can be enhanced without substantial changes to the conventional manufacturing process.
