Abstract

In this study, polyamide 6 (PA6) polymer, which is in the engineering polymers class, was used as the main matrix material. The aim of this study was to determine the mechanical properties of pure polyamide 6 polymer and 5wt.% glass bead filled polyamide 6, 15wt.% glass fiber reinforced polyamide 6 and 5wt.% glass beads/15wt.% glass fiber and 4wt.% Ethylene-Propylene-Diene-Monomer filled polyamide 6 hybrid composites. Polyamide-6-based polymer composites were first produced in granular form in a twin screw extruder, and then the test samples were produced by injection molding methods. Tensile, impact and bending specimens were produced by injection molding method in accordance with ASTM standards. As a result of the study, 5wt.% glass bead added to PA6 polymer increased the tensile strength by 2%, but did not affect the modulus of elasticity much. 15wt.% glass fiber added to PA6 polymer increased the tensile strength by 51.5% and the modulus of elasticity by 85.8%. The EPDM elastomer added to the PA6-5CB-15CE composite increased the impact strength by 14.2% and the elongation at break by 56.2%. Microstructure studies were investigated using scanning electron microscopy (SEM).

Abstract

Otomotiv, beyaz eşya, savunma sanayi, uçak ve uzay sanayinde kullanılan bazı parçaların yüksek mukavemetli olmasının yanında aynı zamanda tok ve darbe dayanımlı olması da istenir. Bu çalışmada, ana matris malzeme olarak mühendislik polimerleri sınıfında yer alan poliamit 6 (PA6) polimeri kullanılmıştır. Katkısız PA6 polimeri ile ağırlık olarak %5 oranında cam bilya (CB) katkılı poliamit 6 (PA6-5CB), %15 oranında cam elyaf (CE) takviyeli poliamit 6 (PA6-15CE) ve %5CB/%15CE/%4 Etilen-Propilen-Dien-Monomer (EPDM) katkılı poliamit 6 (PA6-5CB-15CE-4EPDM) hibrit kompozitlerin mekanik performansları araştırılmıştır. Poliamit-6 esaslı polimer kompozitler önce ikiz vidalı ekstrüderde granül formda üretilmiş sonrasında ise enjeksiyon kalıplama yöntemi ile test numuneleri üretilmiştir. Enjeksiyon kalıplama yöntemi ile ASTM standartlarına uygun olarak çekme, darbe ve eğme numuneleri üretilmiştir. Çalışma sonucunda, PA6 polimerine ilave edilen %5 oranında cam bilya çekme mukavemetini %2 oranında artırırken elastiklik modülünü etkilememiştir. PA6 polimerine ilave edilen %15 oranındaki cam elyaf ise çekme mukavemetini %51.5 oranında, elastiklik modülünü ise %85.8 oranında artırmıştır. PA6-5CB-15CE kompozitine ilave edilen EPDM elastomeri darbe mukavemetini %14.2 oranında, kopmadaki % uzama miktarını ise %56.2 oranında artırmıştır. Mikroyapı incelemeleri ise taramalı elektron mikroskobu (SEM) kullanılarak incelenmiştir.
