STUDY ON THE COMPOSITE OF GLASSFIBER REINFORCED POLYVINYLCHLORIDE(GFRPVC)

The effects of surface treatment and weight loading of glass-fiber on mechanical and thermal properties of fiber reinforced PVC composite (GFRPVC)were studied.The GF/PVC interface and its effect on the properties of GFRPVC were also investigated using SEM.It was found that GFRPVC composite (30wt% of G.F.) had flexure strength of 190MPa,a flexure modulus of 8.90GPa,a tensile strength of 110MPa,a tensile modulus of 8.8GPa,a notched Izod impact strength of 140J/m,a thermal expansion coefficient of 2.23 (×10^-5)℃^-1,and HDT of 84℃.Compared with 96MPa, 2.9GPa,54MPa,2.60GPa,37.6J/m,3.12(×10^-5)℃^-1,78℃ for RPVC, respectively.
