Karbon Fiber Takviyeli Epoksi Matrisli Kompozitlerin Bağlantı Bölgelerinin Mekanik Davranışlarının İncelenmesi

Year 2020, Volume: 1 Issue: 2, 66 - 75, 06.12.2020

Abstract

Bu çalışmada polimer matrisli kompozit malzeme parçalarının farklı yöntemlerle birleştirilmesi sonrası, farklılıkların birleşme bölgesinin çekme kuvvetine etkileri incelenmiştir. Öncelikle çift yönlü dokumaya sahip karbon fiber kumaş takviyeli epoksi kompozit çekme testi numuneleri üretilmiştir. Kompozit numune üretiminde elle yatırma sonrası sıcak presle presleme yöntemi kullanılmıştır. Üretilen numuneler ASTM D412 standardına uygun ölçülerde boyutlandırılmıştır. Numuneler tam ortadan ikiye bölünerek farklı yöntemlerle birleştirilmiştir. Birleştirme yöntemleri vida ile vidalama, piyasada yaygın olarak bulunabilen az maliyetli bir çift bileşenli yapıştırıcı ile yapıştırma, kompozit malzemenin üretildiği laminasyon reçine ile yapıştırma ve aynı laminasyon reçinenin karbon fiber tozu ile katkılandırılarak yapıştırılması şeklindedir. Yapıştırılan numuneler çekme testine tâbi tutularak birleşme kuvvetleri karşılaştırılmıştır. Vida ile birleştirilen bölgenin kopma kuvveti en az değeri verirken piyasada yaygın olarak bulunabilen az maliyetli çift bileşenli yapıştırıcı ile yapıştırılan bölgelerin kopma kuvveti en yüksek değeri vermiştir ve bu değerler sırasıyla 2278,67 N ve 12062 N’dur. Yapılan çalışma kapsamında en düşük kuvvet değeri vidalama tekniği ile birleştirilen numunelerde, en yüksek değer ise çift bileşenli yapıştırıcı ile birleştirilen numunelerde gözlenmiştir.

Investigating the Mechanical Behavior of Joints of Carbon Fiber Reinforced Epoxy Composites

Year 2020, Volume: 1 Issue: 2, 66 - 75, 06.12.2020

Abstract

In this study, after bonding polymer matrix composite joints via different methods, the effect of the methods to tensile force were investigated. Firstly, tensile test specimens of plain weaved carbon fiber fabric reinforced epoxy composite were manufactured. Hot pressing after hand layup method were utilized in production. Specimens were sized in accordance with the ASTM D412 standard. Each sample were cut into half and bonded with different methods. Bonding methods include fastening with bolts, bonding with a low-cost two-component adhesive, widely available in the market, bonding with lamination resin from which the composite material is produced by, and bonding with the same lamination resin with carbon fiber powder. Bonded specimens were subjected to tensile test according to compare joint forces. While the breaking force of the region joined by the bolts gives the least value, the tensile strength of the regions bonded with the low-cost two-component adhesive that can be found in the market has the highest value and these values are 2278,67 N and 12062 N, respectively.
