Abstract: 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.
