PP-g-MAH与氨基化纳米二氧化硅协同增强CF/PP复合材料
Synergistic enhancement of CF/PP composite materials by PP-g-MAH and aminated silica nanoparticles
摘要
Abstract
The strength of the resin itself and the interface strength between the resin and carbon fiber are im-portant factors affecting the mechanical properties of continuous carbon fiber reinforced thermoplastic composites.In order to improve the mechanical properties of continuous carbon fiber reinforced polypropylene(CF/PP)thermo-plastic resin based composites,this paper modified high melt index PP by adding maleic anhydride grafted polypro-pylene(PP-g-MAH)and aminated nano silica(SiO2-NH2).Continuous carbon fiber reinforced polypropylene thermoplastic resin based composites were prepared by melt impregnation and hot pressing.The results showed that the addition of PP-g-MAH and SiO2-NH2 increased the crystallinity of PP by 2.5％,the tensile strength by 4.8％,and the bending strength by 5.3％;the bending strength and interlayer shear strength of CF/PP composite materials were increased by 112.2％ and 66.0％,respectively,to 543.7 MPa and 17.2 MPa.关键词
