Delamination in drilling GFR-thermoset composites
TL;DR: In this article, the influence of drilling and material variables on thrust force, torque and delamination of fiber reinforced thermoset composites was investigated experimentally and the results showed that the presence of sand filler in continuous-winding composites not only raised the values of cutting forces and push-out delamination but also increased their values with increasing cutting speed.
