摘要
Abstract
Two kinds of stiffened cyanate ester resins(7180M and 7180S)were prepared,and the curing re-sponse and mechanical properties were compared with those of the pure resin.The stiffness and crosslinking density of 7180M and 7180S resin matrix were improved by introduction of stiff chain segments with high rigidity and poly-hedral oligomeric silsesquioxane(POSS),and the tensile modulus reached 3 450 MPa(7180M)and 3 400 MPa(7180S),respectively.Compared to CCM55J/CE composites,the interfacial shear strength of CCM55J/7180M and CCM55J/7180S composites were increased by 42.5%and 30.6%,and the transverse tensile strength and interlami-nar shear strength of fiber bundle were increased by 152.2%,91.6%and 18.1%,15.5%,respectively.The en-hanced interfacial properties were attributed to the widened interphase thickness and the gentle interphase modulus transition layer.The boiling water moisture uptake of CCM55J/7180M and CCM55J/7180S composites at 360 h were reduced to 0.67%and 0.83%,respectively.Mass loss and condensable volatiles were reduced to 0.11%,0.095%and 0.04%,0.006%.These results indicated that with the increasing modulus of matrix,the perfect struc-ture of cross-linking network of resin matrix effectively prevented the entrance of water molecules,and improved the anti-hydrothermal and spatial properties of CCM55J/7180M and CCM55J/7180S composites.关键词
