摘要
以玄武岩针刺非织造织物为增强体,以硼酚醛树脂为基体树脂,采用层压复合工艺制备了复合材料,研究了不同针刺工艺对复合材料力学性能的影响。结果表明,相同针刺工艺条件下,复合材料的拉伸强度随复合层压压力的增加先增大后减小,复合材料的弯曲强度随复合层压压力的增加而线性增强;在一定情况下,增强体的孔隙率对复合材料力学性能的影响高于增强体拉伸强度对复合材料力学性能的影响。
The needle felt reinforced composite plates were prepared by using basalt needle punched nonwoven fabric as a reinforcement and boron phenolic resin as a matrix through,and the effect of needle punching process on the mechanical properties of the composites was investigated.The tensile strength of composites exhibited an increasing trend at first and then decreased with an increase of lamination pressure.However,the flexural strength increased linearly with increasing the lamination pressure in the same needle-punching process.In a certain case,the porosity of reinforcement presented a more significant effect on mechanical properties of composites that its tensile strength.
