INFLUENCES OF TEMPERATURE AND HUMID HEAT ENVIRONMENT ON MECHANICALPROPERTIES OF GLASS FIBER REINFORCED COMPOSITE

Abstract

Abstract: Samples of glass fiber reinforced composite are prepared by vacuum aided resin transfer molding process, and the influences of temperature and humid heat environment on mechanical properties of glass fiber reinforced composite are evaluated. The results show that, the aggregation state of the resin changes from glassy state to elastic state with the increasing of temperature during -50~150℃, and the mechanical properties of glass fiber reinforced composite decrease. Similarly, the mechanical properties also decrease with the increasing of test time in humid heat environment. This phenomenon is suggested to be caused by the damage of interface between resin and fibers. This study provides technological support for the engineering-application of glass fiber reinforced composite.

Key words: glass fiber reinforced composite, mechanical properties, temperature, humid heat environment, glass transition temperature, interface
