Preparation and Mechanical Properties of UV-Assisted Filament Winding Glass Fiber Reinforced Polymer-Matrix Composite
摘要
Abstract
This paper studied the preparation and mechanical properties of glass fiber reinforced polymer-matrix composite rings prepared by filament winding assisted by ultraviolet(UV)curing. A ray-tracing method was used to calculate the penetration ability of UV light in the resin casting,and then a typical composite ring with dual-curing characteristics was prepared by UV-assisted curing. The effects of winding speed and thermal initiator concentration on the distribution of fiber fraction and mechanical properties were studied. Microscopic morphology was used for the observation of the differences in fiber volume fraction. Mechanical properties tests and scanning electron micrographs were performed to investigate the failure and damage mechanisms of the composite ring samples. The ray tracing results indicate that the UV light can pass through a single yarn thickness and the energy transmitted is sufficient to cure the back side quickly. The experimental results show that the mechanical properties of the composite ring prepared in this paper are comparable to those of the heat-cured samples,which is sufficient to meet the requirements of the flywheel.关键词
