摘要
以尼龙粒子-1和尼龙粒子-2作为增韧组分[熔点分别为142、217~℃,平均粒径均为(20±3)μm]、环氧树脂(EP)为基体和碳纤维(牌号T700)为增强材料,采用热熔预浸料法和层间增韧法制得可中温(130~℃)固化的EP基复合材料。研究结果表明:引入尼龙粒子后,复合材料的耐热性、压缩性能和弯曲性能无显著变化,但层间剪切强度降低,并且其韧性变化与尼龙粒子熔点相关。经尼龙粒子-1或尼龙粒子-2增韧后,复合材料冲击后的压缩强度(CAI)为265 MPa或183 MPa,比未增韧体系提高了39%或-4%。
With nylon particles-1 and nylon particles-2 as toughening components[melting points at 142, 217℃, and average particle sizes at （20±3） μm], epoxy resin（EP）as matrix and carbon fiber（brand TT00） as reinforced material, the medium temperature （ 130 ℃ ） curing EP based composite was prepared by hot melt presoak method and interlaminar toughening method. The research results showed that the heat resistance, compression properties, and bending properties of composite had no the obvious change, but its interlaminar shear strength was reduced, and its toughness change and melting point of nylon particles were related when nylon particles were introduced into system. The compression strength after impact （CAI） of composite with nylon particles-1 or nylon particles-2 as toughening components, which were 265 MPa or 183 MPa respectively, were 39% or -4% more than those of composite without toughening components.
