In this article, with the help of mathematical modeling curing rate, influence factors directly affecting processes an auto-filler prepared based on unsaturated polyester resin was studied: concentration accelerator, hardener, and temperature. When process, temperature concentrations were taken as initial (input) parameters, rate at various temperatures final (output) parameter.

In this study, thermal risk evaluation and reproduction experiments were conducted based on the case where fire was detected during epoxy-resin curing process, results provide technical data to prevent similar accidents . Epoxy resin (unsaturated polyester resin) is second petroleum product among Class 4 dangerous substances as determined through flash point, combustion ignition point tes ts. a...

Classical dynamic fracture theories predict the surface wave speed to be the limiting speed for propagation of in-plane cracks in homogeneous, linear elastic materials subjected to remote loading. This report presents experimental evidence to the contrary. Intersonic shear-dominated crack growth featuring shear shock waves was observed along weak planes in a brittle polyester resin under far-fi...
