Study On The Deformation Behavior Of A Drilled Sample Prepared From Recycled Polyethylene Reinforced With Natural Waste

Abstract

The research aims to study the deformation behavior when drilling a polymer composite material reinforced with natural waste by studying the effect of the operating process parameters (rotational speed and feed speed) on the hole surface, where a sample consisting of recycled low-density polyethylene (RLDPE) was prepared with an organic filler from wood waste in the form of powder, on a half-hydraulic press. The drilling process was performed using and two types of machines: a conventional Heckert drilling machine with diameters (5, 10, 15 mm), the rotational speed (500, 1000, 1400, 2000 r.p.m), and the feed speed (0.08, 0.20, 0.32 mm/rev), and CO2 laser cutting machine with a speed (5 mm/s) and a power (48 watt). The delamination was calculated and the deformation behavior when drilling was studied Samples on both machines. The results showed that the significant effect of the drilling process parameters on the thermal properties of the composite materials prepared from thermoplastics showed clear deformation behavior, and that as the cutting speed and feed speed increased, the value of the delamination decreased, and the use of the CO2 laser reduces the deformation but burns the edges of the hole.
