Abstract
The present invention relates to a carbon fiber reinforced plastic member provided with high-elongation fiber bundle regions, which are uni-directionally aligned and separately disposed within the plastic member. The plastic member provides a carbon fiber reinforced plastic of lightweight, high strength and high modulus that is safe. Even if it breaks, it shows little scatter of fragments or exposure of dangerous fracture surfaces. Preferably, the high-elongation fiber at break has an elongation exceeding about 10%.
Claims15
A hybrid tubular shaped fibre reinforced plastic member which is characterized in that said member has carbon fibre and high-elongation organic fibre having an elongation at break thereof exceeding about 10%, said high-elongation fibre being contained in the tubular shape of the reinforced plastic member, said carbon fibre and high-elongation fibre, being uni-directionally aligned, and wherein high-elongation organic fibre bundle regions are present separately within the tubular shaped plastic member, and arranged at a pitch, said pitch being no more than 50 mm at right angles to a carbon fibre axis.
A hybrid prepreg which is characterized in that carbon fibre and high-elongation organic fibre are impregnated with a resin, said high-elongation fibre having an elongation at break thereof exceeding about 10%, said carbon fibre and high-elongation fibre, being uni-directionally aligned, and wherein high-elongation fibre bundle regions are present separately within the prepreg, and arranged at a pitch, said pitch being no more than 50 mm at right angles to a carbon fibre axis.
