Abstract

In this research, experimental studies were carried out within the scope of examining the mechanical properties of glass fiber reinforced polymer matrix composite profiles produced by pultrusion method when subjected to temperature shock test. Samples were prepared in accordance with ASTM standards for three-point bending, compression and tensile tests from the U profile composite material produced by the pultrusion method. Some of the samples were subjected to the temperature shock test. The mechanical tests of the samples, which were in ambient conditions and exposed to the temperature shock test, were performed and the results were compared. In the results of working; It has been determined that the strength values obtained as a result of the three-point bending and compression tests of the composite materials exposed to the temperature shock test are higher than the samples that are not subjected to the temperature shock test. In addition, it has been determined that the tensile strengths of the samples subjected to the temperature shock test, obtained in the tensile test, are approximately the same as the tensile strengths of the samples that were not subjected to the temperature shock test.

PULTRUZYON YÖNTEMİ İLE ÜRETİMİ YAPILAN KOMPOZİT MALZEMELERİN SICAKLIK ŞOKU TESTİ SONUCUNDA MEKANİKSEL ÖZELLİKLERİNİN İNCELENMESİ

Abstract

Bu araştırmada, pultrüzyon yöntemi ile üretilmiş olan cam elyaf takviyeli polimer matrisli kompozit profillerin sıcaklık şoku testine maruz bırakılması durumunda mekaniksel özelliklerinin incelenmesi kapsamında deneysel çalışmalar yapılmıştır. Pultrüzyon yöntemi ile üretilen U profili kompozit malzemesinden, üç nokta eğilme, basma ve çekme testleri için ASTM standartlarına uygun şekilde numuneler hazırlanmıştır. Numunelerin bir kısmı sıcaklık şoku testine maruz bırakılmıştır. Ortam koşullarında bulunan ve sıcaklık şoku testine maruz bırakılan numunelerin mekaniksel testleri yapılarak sonuçlar karşılaştırılmıştır. Çalışma sonucunda; sıcaklık şoku testine maruz kalan kompozit malzemelerin üç nokta eğilme ve basma testleri sonucunda elde edilen dayanım değerlerinin sıcaklık şoku testi uygulanmayan numunelere göre daha yüksek olduğu tespit edilmiştir. Bunun yanında, sıcaklık şoku testine maruz bırakılan numunelerin çekme deneyinde elde edilen çekme dayanımlarının sıcaklık şoku testi yapılmayan numunelerin çekme dayanımları ile yaklaşık aynı olduğu tespit edilmiştir.
