Abstract

Abstract: In this study, the equivalent heat conduction model and internal curing process optimization model of the composite material based on the cavity and twisting structure of the plant fiber were established. Also, the effects of temperature, the volume fraction of the plant fiber cavity and twist on the temperature field, curing degree, and curing deformation during the internal curing process of the jute fiber winding composite pipe were analyzed. The accuracy of process simulation was verified by the internal curing experiment based on electromagnetic heating and was combined with using the microstructure test and tensile strength test of the NOL ring. However, in the case of twisted fiber, an extreme effect on the mechanical properties of the composite was noted. Abstract :
