摘要：采用热压成型工艺制备了玻纤网格布增强聚碳酸酯(PC)复合片材,考察了铺层结构、铺层角、增强纤维面密度及基体薄膜厚度对复合片材拉伸性能的影响。结果表明,增强玻纤网格布与基体膜的交替叠层为适宜的铺层结构;拉伸性能随铺层角增大而下降;低面密度的玻纤网格布适宜制备低面密度的"薄型"复合片材;采用厚度较小的基体膜可以制得拉伸性能较好的复合片材。扫描电子显微镜(SEM)分析表明交替的铺层结构有利于基体对低面密度增强纤维的束内浸渍,从而提高片材的拉伸性能。
Composite sheets of fiberglass mesh reinforced polycarbonate were prepared by hot compress molding. The effects of lay-up structure, lay-up angle, area density of fiberglass mesh and the thickness of PC film on tensile property were studied. The results reveal that the alternative lay-up structure of reinforcement mesh and matrix film is optimal and tensile property declines as lay up angle increases. Fiberglass mesh with lower area density is appropriate for thinner composites. Composite sheets fabricated with thinner PC film show better tensile property. SEM analysis shows that alternative lay-up structure is favorable to the immersion of the fiber bundle of fiberglass mesh with low area density in the melting matrix, and thus the improvement of tensile property.
