Güçlendirilmiş Polyester Reçine Matrisli Kompozit Malzemelerin Tek Yönlü Karbon Fiberler Üzerinde Katmanların Etkisi

Öz

Bu çalışmada, 12 filament numaralı tek yönlü karbon fiber takviyelerin polyester matris içerisine bir, iki ve üç katman oluşturacak şekilde oda sıcaklığında elle yatırma yöntemiyle yerleştirilmesiyle kompozit malzemeler üretilmiştir. Numuneler, standartlara uygun olarak elyaf yön açısı doğrultusunda bir kalıp yardımıyla kompozit plakalardan hazırlanır. Numunelerin mekanik özelliklerinin belirlenmesi için çekme, eğilme ve düşme ağırlıklı düşük hızlı darbe testleri yapılır. Çekme testi sonucunda katmanlar arasında en yüksek çekme dayanımı değeri iki katmanlı tek yönlü elyaf takviyeli kompozit malzemelerde elde edilmiştir. Eğilme testlerinde tek yönlü karbon elyaf takviyelerin en yüksek elastisite değerleri 00 dogrultusunda üç katmanlı kompozit malzemelerde gözlenmektedir. 00 tek yönlü güçlendirilmiş kompozit malzemelerin düşen ağırlıkta düşük hız darbe testlerinin en yüksek deformasyon değerlerine sahip kompozit malzemelerde görülmektedir.

The Effect of Layers on the Unidirectional Carbon Fibers of the Reinforced Polyester Resin Matrix Composite Material

Abstract

In this study, composite materials are produced, placing unidirectional carbon fiber reinforcements with 12 filament numbers in a polyester matrix to form one, two, and three layers at room temperature through the hand lay-up method. The samples are prepared from composite plates with the help of a mold in line with the fiber direction angle by the standards. The tensile, three-point bending, and falling weight low-speed impact strength values of the samples were measured and were investigated the mechanical performance of the specimens. As a result of the tensile test, the highest tensile strength value among layers is obtained in the two-layer unidirectional fiber-reinforced composite materials. In bending tests, the highest elasticity values of unidirectional carbon fiber reinforcements are observed in three-layer composite materials with a fiber direction angle of 00. 00 unidirectional fiber-reinforced one-layer composite materials are observed in composite materials with the highest deformation values in the falling weight low-velocity impact tests.
