摘要
Abstract
High-performance continuous fiber reinforced thermoplastic resin-based composites possess properties such as high toughness,fatigue resistance,impact resistance,and reprocessable capabilities.These characteristics allow them to address the shortcomings of traditional thermosetting composites,which includes insufficient toughness,tendency to delaminate under low-speed impacts,and low fatigue limit.In this study,using AC8201 resin as the matrix and domestic high-strength glass fiber S6C10 as the reinforcing material,a continuous high-strength glass fi-ber reinforced polyether-ether-ketone thermoplastic prepreg with the grade of S6C10/AC8201 was successfully pre-pared by the suspension hot melt method.The appearance of the prepreg was uniform and flat without dry yarn,and the resin content of the prepreg was 24.8％with excellent physical properties and processability.Utilizing thermo press molding technology,composite laminates made from S6C10/AC8201 had been fabricated.These laminates fea-tured even thickness distribution,no dry fibers,and exhibited outstanding mechanical performance and fatigue re-sistance.Specifically,the bending strength of the developed composite material reached 1 818 MPa,representing 13.6％improvement compared to that of TC1200 prepreg.Furthermore,the 0° tensile fatigue limit strength was measured at 490 MPa,showcasing a significant enhancement of 21.3％over that of thermoset S6-reinforced high-temperature epoxy composites.关键词
