Drilling analysis of thin woven glass-fiber reinforced epoxy composites

摘要: Abstract In this study, the influence of cutting speed (16.3, 32.7 & 65.3 m/min) and feed (0.025–0.1 mm/rev) on temperature, thrust ‎force, torque, delamination factor, surface roughness bearing strength in drilling thin woven glass-fiber reinforced epoxy (GFRE) composites was investigated, for first time, grouped one article. The results tests showed that force ( F t ), factor are increased with increasing vice versa induced temperature. Drilling GFRE at lower (16.3 m/min) result temperature rise, higher force, torque accordingly, compared drilled 65.3 m/min. close to glass transition is useful reducing , thus obtaining better levels. critical onset push-out predicted different uncut layers, front ‎of drill chisel edge, using some analytical models.‎ For [0°] 8 composites, [ABD] stiffness matrices effectively ‎represented by [0°/90°] 4s cross-ply laminate advantages elastic properties were determined rule mixtures (no need perform ‎mechanical tests).
