Cam ve Bambu Lifleriyle Takviyelendirilmiş Vinilester Kompozitlerinin Mekanik Özelliklerinin İncelenmesi

Son yıllarda artan çevresel kaygılar, azalan kaynaklar gibi önemli problemlere çözüm bulma isteği sonucunda, bileşenleri yenilenebilir kaynaklardan gelen kompozit (yeşil kompozit) üretimi yapmak önem kazanmıştır. Yapılan çalışmaların birçoğu, bitkisel liflerle takviyelendirilmiş polimer matrisli kompozit malzemeler üzerine yoğunlaşmıştır. Bu çalışmada, açık Teflon kalıp kullanılarak dört tip kompozit malzeme üretilmiş; matris malzemesi olarak vinilester reçinesi, takviye malzemesi olarak ise bambu ve cam lifleri kullanılmıştır. Kompozitlerde bambu lifi-vinilester, cam lifi- vinilester, bambu+cam lifi-vinilester grubu için lif/reçine ağırlık oranı %12 olarak belirlenmiştir. İlave olarak lif/reçine ağırlık oranı %24 olan bambu+cam lifi-vinilester kompoziti hazırlanmıştır. Kompozitte bambu ve cam lifi takviyesinin karşılaştırılması, bambu+cam lifinin beraber kullanılmasının etkisi gibi araştırmaların yanı sıra lif ağırlık oranının etkisi de araştırılmıştır. Kompozit numuneler; çekme, 3 nokta eğme, darbe ve sertlik testlerine tabi tutulup, sonuçlar karşılaştırılmıştır.

Investigation of Mechanical Properties of Glass and Bamboo Fiber Reinforced Vinylester Composites

As a result of the desire to find solutions to important problems such as increasing environmental concerns and decreasing resources in recent years, it has become important to produce composite (green composite) whose components are from renewable sources. Many studies have focused on polymer matrix composite materials reinforced with plant fibers. In this study, four types of composite materials were produced by using open Teflon molds. Vinylester resin was used as matrix material and bamboo and glass fibers were used as reinforcement material. The weight ratio of fiber / resin was determined as 12% for composites of bamboo fiber-vinylester, glass fiber-vinylester, bamboo + glass fiber-vinylester group. In addition, the bamboo + glass fiber-vinylester composite was prepared which had a fiber / resin weight ratio of 24%. The effects of fiber weight ratio as well as research on the comparison of bamboo and glass fiber reinforcement in the composition and the effect of the use of bamboo + glass fiber were investigated. Tensile, 3 point bending, impact and hardness tests were performed and the results were compared.
