Abstract

In this study, the effect of different amounts of pine and acorn powder reinforcement on the mechanical properties of glass fiber reinforced composites was investigated. Tensile, compression and three-point bending tests of composites which produced as particle reinforcements were carried out at room temperature and these results were compared with pure glass fiber reinforced composites. Besides, the variation of compressive strength values of composites after impact loading was investigated with the help of compression tests. 20J, 30J and 40J are determined as the impact energy level. According to the results, the tensile strength values of composites increased in the case of 2.5 wt% and decreased in the case of 5 wt% pine cone and acorn powder loadings. Also, bending strength values did not change significantly in the acorn powder reinforced composites, but it decreased in the pine cone powder reinforced composites.

Özet

Bu çalışmada, cam elyaf takviyeli kompozitlerin mekanik özelliklerine ağırlıkça farklı oranlarda çam ve meşe palamudu tozu takviyesinin etkisi incelenmiştir. Parçacık takviyeli olarak üretilen kompozitlerin çekme, basma ve üç nokta eğilme deneyleri oda sıcaklığında gerçekleştirilmiş ve bu sonuçlar saf cam elyaf takviyeli kompozitler ile karşılaştırılmıştır. Ayrıca, düşük hızlı darbe sonrası bası testleri yardımıyla kompozitlerin darbe yüklemesinden sonraki bası dayanımlarının değişimi incelenmiştir. Darbe enerjisi olarak 20J, 30J ve 40J belirlenmiştir. Elde edilen sonuçlara göre, iki farklı takviye malzemesinde kompozitlerin çekme mukavemeti ağırlıkça %2,5 oranında artarken %5 oranında ise azalmaktadır. Eğilme mukavemet değerleri ise meşe palamudu takviyesinde önemli oranda değişmezken çam kozalağı takviyesinde azalmaktadır.
