Analysis of Mechanical Properties and Exploration of Failure Mechanism for Nonwoven Reinforced Composites

Abstract:

This experiment made use of hand lay-up to generate nonwoven reinforced composites which used glass fiber nonwovens, glass fiber felt and PE hot rolling nonwovens as the reinforcement, thermosetting unsaturated resin as the matrix, and tested their tensile and bending mechanical properties, then analyzed mechanical properties by gray relative analysis. The results show that when glass fiber felt is used as reinforcement and its content greater than 60%, the comprehensive mechanical properties of the composite are the best. At the same time, we observed the tensile fractures to analyze the failure mechanism of the composites.
