Abstract:
The present invention pertains to a carbon fiber reinforced plastic, and provides a carbon fiber reinforced plastic laminated body that is low cost and superior in moldability, mechanical characteristic balance, and impact resistance. The laminated body has three or more layers, and has the following (B) layer between two layers of a fiber reinforced resin sheet, (B) layer: A resin sheet in which the displacement, in an S-S curve waveform obtained by the following high-speed punching test, from a peak value of the test force (kN) to an 85%—attenuation value is not less than 22 mm. High-speed punching test: Impact absorption energy is calculated by using an impact testing machine in compliance with ISO6603-2 standard. A 100 mm×100 mm test piece is cut out from a sheet having a thickness of 2 mm. The diameter of a striker is 12 mm. the diameter of an opening section of a holding tool is 76 mm, and the impact speed is set to 5 m/sec.
