The automotive and aerospace industries often use Carbon Fiber Reinforced Plates (CFRP) to reduce car weight. CFRP is composed of a stack of carbon fiber thin surfaces where the fibers are line up in a fixed direction to archive light weight and high strength. However, the use of a common self-tapping screw for plastics will disarrange, spilt and strip the fibers on CFRP, reducing strength and destroying appearance; therefore it cannot achieve stable screw fastening. In light of this, Nitto Seiko Co. Ltd successfully developed (…)
