摘要
以短切玻璃纤维增强改性不饱和聚酯树脂为芯板,玻璃纤维布为面层,制备玻纤增强不饱和聚酯树脂夹层板。通过改变芯层短切玻璃纤维的含量研究夹层板复合材料的性能。研究表明:当短切玻璃纤维含量低于50%(wt,质量分数,下同)时,复合板的力学性能随纤维含量的增加而逐渐增强;短切玻璃纤维含量为50%时,复合板力学性能达到最优,其中拉伸强度、弯曲强度、冲击强度分别达到152.48MPa、299MPa、164kJ/m2,而且材料具有较好的耐热性和热稳定性,初始分解温度达到79℃。
Abstract
Chopped glass fiber reinforced unsaturated polyester resin was used as the core board,glass fiber cloth as the surface layer,the glass fiber reinforced unsaturated polyester resin sandwich laminated composite was prepared.By changing the content of core layer chopped glass fiber to study the properties of composite.It showed that when the content of chopped glass fiber was below 50%,as the content of chopped glass fiber increased,the mechanical properties of composites increased first and then decreased.When it was 50%,the mechanical properties reached the maximum.The tensile strength,bending strength,impact strength reached 152.48MPa,299MPa and 164kJ/m2 respectively.And it was also found that the composite had a good heat resistance and thermal stability,the initial decomposition temperature reached 79℃.
