Mechanical Properties and Bend Ability of a Plain-Woven Carbon Fibre Reinforced Thermoplastic Sheet

Abstract
The mechanical properties of a carbon fibre reinforced thermoplastic (CFRTP) sheet were evaluated, which is composed of plain-woven carbon fibre fabrics impregnated with polypropylenematrix resin.Usingthe specimens whose longitudinal direction is parallel to orinclined at 45 degrees from the fibre direction,uniaxial tensile tests, three-point flexural tests, and Charpy impact tests were performed to investigate the anisotropy ofmechanical characteristics.In addition, cold and warm V-bending tests were performed to investigate the bendability of the CFRTP sheet.The effectiveness of a novel technique of bending a CFRTP sheet sandwiched between highly ductile sheets was confirmed in terms of reducing the springback angle.
