Abstract

Bu çalışmada, çok duvarlı karbon nanotüp (ÇDKNT) katkısının PA6 nanokompozitlerin termal, termo-mekanik ve tribolojik özelliklere etkisi incelenmiştir. ÇDKNT katkılı PA6 nanokompozit granüller çift vidalı ekstruder ile üretilmiştir. Elde edilen granüllerden enjeksiyonla kalıplama tekniği kullanılarak standartlara uygun numuneler üretilmiştir. PA6 nanokompozitlerin ergime sıcaklığı ve kristallenme oranı diferansiyel taramalı kalorimetre (DSC) analizi ile depolama modülü ve kayıp modülü ise dinamik mekanik analiz (DMA) ile belirlenmiştir. Aşınma testleri kuru ortam şartları altında çelik diske karşı pim-disk sistemi ile gerçekleştirilmiştir. Çalışma sonucunda, ÇDKNT katkılı PA6 polimerinin ergime sıcaklığı sabit kalırken kristallenme oranı artmıştır. Artan ÇDKNT miktarına bağlı olarak PA6 kompozitlerin depolama modülü ve kayıp modülü artmıştır. Triboloji testleri sonucunda, artan kayma hızı ve yüke bağlı olarak sürtünme katsayısı artmıştır. En düşük sürtünme katsayısı ve aşınma oranı %0.3 ÇDKNT katkılı PA6 nanokompozitinde elde edilmiştir.

The Investigation of Thermal, Thermo-Mechanical and Tribological Properties of Multi-Walled Carbon Nanotube filled Polyamide 6 polymer

Abstract

In this study, the effects of multi-walled carbon nanotube (MDCT) on thermal, thermo-mechanical and tribological properties of PA6 nanocomposites were investigated. MWCNT filled PA6 nanocomposite granules are produced with twin screw extruder. And then, test specimens were produced using the injection molding technique. Melting temperature and crystallization ratio were determined by differential scanning calorimetry (DSC) analysis and also storage modulus and loss modulus were determined by dynamic mechanical analysis (DMA) of PA6 nanocomposites. Wear tests were carried out under dry conditions against steel disc with using pin-on-disc device. As a result of this study, the crystallization ratio increased while the melting temperature remained stable for PA6 nanocomposites. Storage modulus and loss modulus of PA6 nanocomposites increased with the MWCNT amount. The coefficient of friction of PA6 nanocomposites increased with increasing sliding speed and load. The lowest coefficient of friction and wear ratio was obtained in the 0.3%wt. MWCNT filled PA6 nanocomposite.
