Abstract


Compared with homogeneous materials, composite materials have high specific strength, specific module, well resist fatigue, advantage shock absorption, and unique anisotropic convenient opportunities in design Composites applied in aviation, auto and military filed more and more.In this paper, prepared high-performance glass fiber reinforced PVC Composite through molding process. Through the molding process parameters on the thickness, fiber width, size of the grid, analysis the reasons for performance differences of Laminates in essence. Analyzed the mechanical properties through tensile experiments .Found that on the temperature 280℃~ 300℃, pressure 2.5 ~ 3MP, time 40 ~ 60s the Laminates have the best mechanical properties.In the molding process the fiber bundles move with the PVC resins. Due to the different cooling in different parts of laminates, Led to the non-uniform of the fiber grid size within the laminates. In the different molding conditions, made the non-uniform fiber grid size are different because of the different situations. In this paper, analyze the relationship between the distribution of the fibers and the molding conditions.The main purpose of this study is to explore the manufacturing process of the continuous fiber reinforced thermoplastic composite sheet is feasibility, find out the efficient methods of production technology methods for continuous fiber reinforced thermoplastic composite sheet according to the production of plastic processing technology.
