TALK VE EPDM MİKTARININ PP/TALK/EPDM KOMPOZİTİNİN MEKANİKSEL ÖZELLİKLERİNE ETKİSİNİN İNCELENMESİ

Bu çalışmada, talk ve EPDM miktarının PP/Talk/EPDM kompozitlerinin çekme ve darbe dayanımı gibi mekanik özellikleri üzerine etkileri incelenmiştir. Bu amaçla, PP polimerine %15 talk ve % 5-20 oranlarında EPDM elastomeri ilave edilmiştir. Karışım çift vidalı ekstruderde gerçekleştirilmiş olup, çekme ve darbe numuneleri enjeksiyonla kalıpla tekniği kullanılarak gerçekleştirilmiştir. Çalışma sonucunda, PP polimerine ilave edilen talk minerali ile çekme dayanımı ve elastisite modülü artarken darbe dayanımı azalmıştır. Bununla birlikte, PP/Talk/EPDM polimer kompozitinde artan EPDM miktarı ile çekme dayanımı ve elastisite modülü azalırken darbe dayanımı artmıştır. Kırılma analizleri SEM analizi ile yapılmıştır

Investigation of The Effect of The Amount of Talk and EPDM onMechanical Properties of PP/Talc/EPDM Composites

In this study, the effect of talc and EPDM content on mechanical properties such as tensile and impact of PP/Talc/EPDM composite samples were examined. For this purpose, 15% talc and 5-20% EPDM was added to PP polymer. The mixture has taken placed in a twin screw extruder, and tensile and impact specimens were performed using the injection molding technique. As a result of, the tensile strength and modulus of elasticity increased while impact strength increased with talc added to PP polymer. Furthermore, tensile strength and modulus of elasticity decreased while impact strength increased with increase amount of the EPDM in the PP/Talk/EPDM polymer composite. Fracture surface analyzes were performed by SEM analysis
