Abstract
Using recycled carbon fiber(RCF)and polypropylene(PP)as raw materials,RCF/PP felt is pre-pared through non-woven process,and then prepared into RCF/PP composite materials through hot pressing molding to investigate the non-woven process parameters and mold pressing parameters as well as the material performance.The results demonstrate that:The needling process adopts a needling density of 15 pin/cm2 and a needling depth of 10 mm;the hot bonding process uses a pressure of 130～180 N/cm2 and a temperature of 160～180 ℃.The com-posite material consolidated by acupuncture is hot pressed and formed at 190 ℃ and 6 MPa;the composite material that is thermally bonded and consolidated is formed by hot pressing at 177～180 ℃ and 7 MPa.The tensile proper-ties of the CD direction of needle-punched felt are 77.8％higher than those of the PD direction,while thermal bonded felt are 59.3％higher than those of the PD direction.RCF/PP composite materials exhibit a certain degree of anisotropy.关键词
