Abstract

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

Abstract

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.
