Investigation of tensile properties of hybrid polymer matrix and glass fiber reinforced polymer composites

Abstract

In this study, hybrid matrix mixtures with different matrix phase resin types were prepared and 5%, 10% and 20% chopped E type glass fibers were added to these mixtures. The orthophthalic, isophthalic and terephthalic polyester resins were each mixed with each other and epoxy-based vinyl ester resin in different combinations as double and triple hybrid matrix mixtures. The tensile properties of the composites produced were determined. As a result of the study, as the fiber ratio increased, the hybrid matrix composites were seen to turn into a more rigid structure and the highest tensile mechanical properties were obtained in the blends containing 20% fiber and vinyl ester resin. It was determined that orthophthalic + vinyl ester (OV) mixture has the highest rigidity in all mixtures prepared with two types of hybrid resin matrix. When the tensile properties of the composites with two types and three types of hybrid resin matrix were compared with each other, it was seen that there were no significant differences.

Hibrit polimer matrisli ve cam lifi takviyeli polimer kompozitlerin çekme özelliklerinin incelenmesi

Abstract

Bu çalışmada, matris fazı farklı reçine türlerinden oluşan hibrit matrisli karışımlar hazırlanmış ve bu karışımlar içerisine ağırlıkça %5, %10 ve %20 oranlarında kırpılmış E tipi cam lifleri ilave edilmiştir. Ortoftalik, izoftalik ve tereftalik polyester reçinelerinin her biri kendi aralarında ve daha sonra epoksi bazlı vinilester reçine ile farklı kombinasyonlarda ikili ve üçlü hibrit matrisli karışımlar oluşturacak şekilde karıştırılmıştır. Üretilen kompozitlerin çekme özellikleri belirlenmiştir. Çalışma sonucunda, lif oranı arttıkça, hibrit matrisli kompozitlerin daha rijit bir yapıya dönüştüğü görülmüş ve en yüksek çekme mekanik özellikleri %20 lif oranında ve vinilester reçinesinin bulunduğu karışımlarda elde edilmiştir. İki tip hibrit reçine matrisli olarak hazırlanan tüm karışımlar içerisinde ortoftalik + vinilester (OV) karışımının en yüksek rijitliğe sahip olduğu belirlenmiştir. İki tip ve üç tip hibrit reçine matrisli kompozitlerin çekme özellikleri birbirleriyle karşılaştırıldığında, anlamlı farklılıkların oluşmadığı görülmüştür.
