CFRP sheet, laminate using CFRP sheet, and manufacturing method of CFRP sheet

摘要

Problem to be solved: to provide a CFRP sheet with excellent mechanical strength such as tensile strength and excellent visibility of the visible surface.A transparent resin layer C is formed outside the surface layer of the CFRP layer s to form a CFRP sheet andCFRP layer sA large number of UD sheet pieces which are bonded and integrated by a matrix resin m in a state where continuous fiber like carbon fibers fIn the state where the direction of the fiber of each sheet piece is randomly orientedAndWhile each of the sheets is placed in a two dimensional direction so as to overlap with each other, they are bonded to each other by a matrix resin M.Although the backside layer of the CFRP layer s or the UD sheet piece p q... Of the intermediate layer is rectangular, theThe surface layer UD sheet PThe average thickness is smaller than that of the UD sheet or Q of the back layer or the intermediate layerAndIt is composed of at least a part of the sheet which is distorted in a non rectangular shape.Diagram
