Abstract

Bu çalışmada, Karbon Fiber Takviyeli Kompozit Malzemelerin (CFRP) kuru ve kriyojenik şartlar altında farklı kesme parametreleri ve farklı çaplı matkaplarla delinmesi, delaminasyon hasarı, delik çapı ve yüzey kalitesine etkisi de-neysel olarak incelenmiştir. Deneysel çalışmada iki farklı kesme hızı (20 ve 50 m/dak.), dört farklı ilerleme miktarı (0.075mm/dev., 0.15mm/dev., 0.225mm/dev. ve 0.3mm/dev) ve 2 farklı çaplı matkaplar (4 mm ve 6 mm) kuru ve kriyojenik şartlar altında yapılan deneysel tasarımın değerleri uygulanmıştır. Sonuçlar, daldırma kriyojenik tekniği ile CFRP'nin delinmesinin kolaylaştığı, delinmiş parçaların yüzey pürüzlülüğünü azaltarak işlenebilirliği büyük ölçüde artırdığını göstermiştir. Bununla birlikte, itme kuvveti ve delaminasyon faktörü artmıştır.

Experimental Study on the Dirilling of the Carbon Fiber Reinforced Polymer Composites under Dry and Criyogenic Conditions

Abstract

In this study, the effect of drilling Carbon Fiber Reinforced Products (CFRP) under dry and cryogenic conditions with different diametered drill bits and different cutting parameters on delamination injury, hole diameter and on surface quality were investigated experimentally. Two different cutting speed (20 and 50 m/min), four different moving amount (0.075 mm/rev, 0.15 mm/rev, 0.225 mm/rev and 0.3 mm/rev) and two different diametered drill (4 mm and 6 mm) values for experimental design have been applied under dry and cryogenic conditions in this study. The results showed that the penetration of CFRP by the immersion cryogenic technique was facilitated, greatly improving the machinability by reducing the surface roughness of the drilled parts. However, thrust and delamination factor increased.
