Experimental Investigation of the Effects of Processing Parameters on Drilling of S-Glass Fiber Reinforced Polymer Composites

Abstract

Fiber reinforced composite materials have become one of the indispensable materials of today's industry. These materials are used alone or in multiples through assembly after the production processes. They can be assembled as either removable or non-removable by drilling holes in the structure where they will be installed. In this study, the hole quality resulting from drilling S-glass fiber reinforced polymer composite material using different cutting parameters and wood drills of different diameters and the effect of cutting parameters were investigated. To define the hole quality, delamination and surface roughness (Ra) were examined and evaluated. Using the Taguchi method, the relationships of cutting parameters on delamination and surface roughness were analyzed and variance analysis was performed. The analysis revealed that the most important parameter for input and output delamination factors was determined to be the drill diameter. The lowest surface roughness was measured in experiments performed with 10 mm diameter drill, a feed rate of 40 mm/min and a speed of 1000 rpm.

S-Cam Fiber Takviyeli Polimer Kompozitlerin Delinmesinde İşleme Parametrelerinin Etkilerinin Deneysel Olarak İncelenmesi

Abstract

Fiber takviyeli kompozit malzemeler günümüz endüstrisinin vazgeçilmez malzemeleri arasına girmiştir. Bu malzemeler üretim süreçleri sonrasında tek başlarına ya da montaj yoluyla çoklu olarak kullanılırlar. Montajlı olarak çalışacakları yapı içerisinde üzerine matkaplar ile açılan delikler vasıtasıyla sökülebilir ya da sökülemez olarak birleştirilirler. Bu çalışmada, S-cam fiber takviyeli polimer kompozit malzemenin farklı kesme parametreleri ve farklı çaplardaki ağaç matkapları kullanılarak delinmesi sonucunda oluşan delik kalitesi ve kesme parametrelerinin etkisi araştırılmıştır. Delik kalitesini tanımlamak için delaminasyon ve yüzey pürüzlülüğü (Ra) incelenerek değerlendirilmiştir. Taguchi metodu kullanılarak kesme parametrelerinin delaminasyon ve yüzey pürüzlülüğü üzerindeki ilişkileri analiz edilmiş ve varyans analizi yapılmıştır. Yapılan analizler ile giriş ve çıkış delaminasyon faktörleri için en önemli etken parametre matkap çapı olarak tespit edilmiştir. En düşük yüzey pürüzlülüğü 10 mm çapında matkapla, 40 mm/dak ilerlemede ve 1000 devir/dak devir sayısında yapılan deneylerde ölçülmüştür.
