[1] UD (unidirectional) pre-preg sheets
[2] Cloth materials pre-preg


[1] Thin layer pre-preg materials with high physical property and high functions using base material manufacturing technologies
[2] High functional pre-preg materials using resin compounding technologies
[3] Provision of tailored pre-pregs according to customer specifications
[4] Response to proper-amount production in line with customerdemands

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.
