3k twill matte carbon fiber strip sheet panels

The mechanical properties and drawing process of multilayer CFRP sheets with various pre-impregnated thicknesses were investigated in this study. Drawing is a well-established process for manufacturing laminated CFRP structures. Providing a high strength-to-weight ratio of produced parts, it is one of the primary technologies in the vehicle industry used to satisfy energy roadmaps and for green design. In this study, the following findings were obtained:
New high-performance multilayer CFRP sheets were developed. They were fabricated with standard and extremely thin-ply prepreg layers and have noteworthy mechanical properties such as pseudo-ductile metal-like tensile stress–strain responses. The proposed laminated CFRP composites have approximately 1400 MPa strength and 30% elongation, compared to those of AHSS, giving it a sufficiently high strength-to-weight ratio for structural use. Thus, its use can reduce the mass of parts, improve their properties, and reduce their cost.
