Bu çalışma, katkısız poliamit 6.6 (PA6.6) ile ağırlıkça %10-20-30 oranlarında cam bilya içeren poliamit 6.6 kompozitlerin mekanik ve mikroyapı özelliklerini incelemek için yapılmıştır. Cam bilya katkılı Poliamit 6.6 kompozitler, endüstriyel tip ikiz vidalı bir ekstrüder makinesinde granül formda üretilmiştir. Deneylerde kullanılan mekanik test numuneleri geleneksel enjeksiyon makinesi kullanılarak basılmıştır. Çalışma sonucunda, PA6.6 polimerine ilave edilen cam bilya çekme dayanımını, kopmadaki uzama miktarını ve charpy darbe dayanımını azaltırken elastiklik modülünü artırmıştır. Mikroyapı incelemeleri için taramalı elektron mikroskobu (SEM) kullanılmıştır. Mikroyapı incelemelerinde cam bilyaların polimer matris içinde homojen olarak dağıldığı gözlenmiştir.

The Effect of Glass Beads Content on the Mechanical Behaviour of Glass Beads Filled Polyamide-6.6 Composites

Öz

This study was carried out to investigate the mechanical and microstructural properties of unfilled polyamide 6.6 (PA6.6) and glass bead filled polyamide 6.6 composites at 10-20-30% by weight. Glass bead filled Polyamide 6.6 composites were produced in granule form in an industrial type twin screw extruder machine. The mechanical test specimens used in the experiments were molded using a conventional injection molding machine. As a result of the study, glass beads filled to PA6.6 polymer matrix decreased the tensile strength, elongation at break and charpy impact strength, while increasing the tensile modulus. Scanning electron microscope (SEM) was used for microstructure studies. In the microstructure investigations, it was observed that the glass beads were homogeneously dispersed in the polymer matrix.
