Abstract

Polyamides are preferred polymer materials for manufacturing industrial products due to their lightness, resistance to corrosion, ease of processing, and recyclability. In this study, the machinability properties of Polyamide 6 (PA6) polymer composite plates reinforced with chopped carbon fiber (CF) and multi-walled carbon nanotube (MWCNT) in different proportions were investigated by the drilling method using different cutting tools and cutting parameters. The experiments were carried out according to the L16 orthogonal array. Drilling experiments were carried out in a dry environment. The deformations occurring on the inlet and outlet surfaces of the drilled samples were calculated, and the surface roughness (Ra) of the hole walls was measured. According to the results obtained, the particle addition made to the PA6 polymer reduced the Ra. It has been observed that high cutting speed and low feed rate are ideal parameters to achieve low Ra and low inlet-outlet deformations.

Katkılı Poliamid 6 Polimer Kompozitin Delinme Performansının İncelenmesi

Abstract

Sahip oldukları hafiflik, kimyasallara karşı dayanıklılık, işlenebilme kolaylığı ve geri kazanılabilme özellikleri nedeniyle termoplastikler endüstriyel ürünlerde tercih edilmektedirler. Bu çalışmada, farklı oranlarda kırpılmış karbon elyaf (KE) ve çok duvarlı karbon nanotüp (ÇDKNT) ile takviye edilmiş Poliamid 6 (PA6) polimer kompozit levhaların işlenebilirlik özellikleri, farklı kesici takımlar ve kesme parametreleri kullanılarak delinme yöntemi ile incelenmiştir. Deneyler L16 ortogonal tasarıma göre yapılmıştır. Delme deneyleri kuru ortamda gerçekleştirilmiştir. Delinen numunelerin giriş ve çıkış yüzeylerinde meydana gelen deformasyonlar hesaplanmış ayrıca delik duvarlarındaki yüzey pürüzlülükleri ölçülmüştür. Elde edilen sonuçlara göre PA6 polimerine yapılan partikül katkısı yüzey pürüzlülüğünün azalmasını sağlamıştır. Düşük yüzey pürüzlülüğü ve düşük giriş-çıkış deformasyonları elde etmek için yüksek kesme hızı ve düşük ilerlemenin ideal parametreler olduğu görülmüştür.
