Point of the Proposed Technology

Effect(s)

New Technology

Raw materials in use:　carbon fibers, glass fibers, aramid fibers, and other high-strength fibers.
　　　　　　 　　　 　Epoxy resin, phenol resin, and others
　　　　　　 　　　 　Functional pre-preg materials/light shielding materials, flame-retardant materials, non-combustible matters, etc. based on the resin compounding technology
Width:　　　 　　　 　1,000 mm (at the time of mass production), 300 mm (the minimum width corresponding to test production)
Thickness:　 　　　 　Minimum: 0.04 mm; maximum: 0.35 mm (performance-based); Thickness level can be adjusted.Surface smoothness: High surface smoothness has made possible the application to processes such as ATL/AFP.
Mechanical properties: High performance to realize the strength of theoretical values according to the compounding rule.
Tailored response:　 　It is possible to respond to individual setting in line with customer specifications.
