Karbon Fiber Kompozit Sandviç Levhaların Yanal Mukavemet Davranışlarının Araştırılması

Bu çalışmada, çekirdek yapısı ve yüzey kapakları karbon fiber kompozit malzemeden oluşan sandviçlevhaların imalatı gerçekleştirilmiştir. Sandviç levhaların çekirdek yapıları kare kesitli olup üretim,herhangi bir yapıştırıcı malzeme kullanılmadan yapılmıştır. Üretimi tamamlanan numunelerin yanalyüzeylerine, üniversal çekme-basma test cihazı yardımıyla basma testi uygulanarak kuvvet-yerdeğiştirme değerleri kaydedilmiştir. Farklı çekirdek yüksekliğine ve yoğunluğuna sahip olan numunelerinyanal basma dayanımları hesaplanmış ve hasar davranışları incelenmiştir. Sayısal çalışmada yanal kritikburkulma yükleri ANSYS programında hesaplanarak sonuçlar deneysel verilerle karşılaştırılmıştır.

Investigation of Edgewise Strength Behavior of Carbon Fiber Composite Sandwich Plates

In this study, manufacturing of sandwich plates which are made of entirely carbon fiber composite reinforced epoxy resin material was carried out. Core structure of sandwich plates are square cross- section and core structure was fabricated without any adhesively materials. The force-displacement values were saved by applying an edgewise compression test with the help of universal tensile test machine. Then, edgewise compressive strengths of specimens having different cores height and density were calculated and presented as graphical. In the numerical study, edgewise critical buckling loads were calculated in the ANSYS program and the results were compared with experimental data.
