Abstract
Bu çalışmanın amacı; oda sıcaklığında ve farklı enerji değerlerinde ağırlık düşürme testlerine maruz bırakılmış tabakalı kompozit plakalarda darbe sonrası bası (DSB) mukavemetlerinin deneysel olarak belirlenmesidir. Kompozit plakalar farklı lif yönlenme açılarına ([0°/90°/0°/90°]S ve [0°/90°/+45°/-45°]S) sahip sekiz tabakadan oluşmaktadır. Darbe deneyleri 10, 20, 30, 40, 50, 60 ve 70 J enerji değerlerinde yapılmıştır. Darbeye uğramış ve uğramamış numunelerin darbe sonrası bası mukavemetleri belirlenmiştir. Deneyler sonucunda; enerji seviyesi arttıkça numunelerin darbe sonrası bası mukavemetleri azalmaktadır. Bununla birlikte, darbe sonrası bası mukavemeti [0°/90°/0°/90°]S lif yönlenme açısına sahip numunelerde daha yüksektir.
The purpose of this study is determining the compression after impact (CAI) strength of laminated composite plates subjected to drop weight tests under various energy values and at room temperature, experimentally. Composite plates are composed of eight layer which has different orientation ([0°/90°/0°/90°]S and [0°/90°/+45°/-45°]S). Impact tests have done at energy levels of 10, 20, 30, 40, 50, 60 and 70 J. Compression after impact strength of damaged and undamaged specimens was determined. As a result of experiments; compression after impact strength decrease by increasing energy level. Nevertheless, the compression after impact strength of specimens which have [0°/90°/0°/90°/]S is higher than others
