Machining of Kevlar Aramid fiber reinforced polymer composite laminates (K-1226) using solid carbide step drill K34

Study on the Machinability of Glass, Carbon and Aramid Fiber Reinforced Plastics in Drilling and Secondary Drilling Operations

“…Drilling in aramid fiber reinforced plastics such as those with Kevlar fibers poses many difficulties. They are used in industry for their chemical stability at high temperatures and wear resistance [43]. Research shows that conventional drilling of these laminates is difficult due to the frictional force generated by the thermal expansion of the aramid material.…”
