Bu çalışmada; tek yön cam fiberlerle takviye edilmiş yapıştırıcılar kullanılarak üretilmiş tek tesirli yapışma bağlantılarının hasar davranışları deneysel yöntemlerle araştırılmıştır. Kompozit levhaların tek tesirli bağlantılar ile birleştirilmesinde epoksi yapıştırıcı emdirilmiş fiberler kullanılmıştır. İki kompozit levha arasına yapıştırıcı emdirilmiş fiber tabakaları kullanılarak bağlantının güçlendirilmesi amaçlanmıştır. Takviye edilmiş yapıştırıcılar ile elde edilen bağlantıların hasar yükleri, takviye edilmemiş yapıştırıcı ile birleştirilmiş bağlantıların hasar yükleri ile karşılaştırılmıştır. Ayrıca fiber takviye açısının etkisini araştırmak için 0o, 15o 30o ve 45o fiber takviye açıları kullanılmıştır. Deneysel çalışma sonucunda yapıştırıcıların takviye edilmesinin hasar yüklerini %7 ‘ye varan oranlarda arttırabildiği belirlenmiştir.

In this study; experimental failure analysis was investigated on adhesively single-lap joints produced using adhesives reinforced with uni-directional glass fibers. Epoxy adhesive impregnated fiber were used to join composite plates with single-lap joints. It is aimed to strengthen the joint by using fiber layers impregnated with adhesive between the two composite plates. The failure loads of the joints obtained with reinforced adhesives were compared with the failure loads of the joints attached to the non-reinforced adhesive. Also, 0o, 15o 30o and 45o fiber reinforcement angles were used to investigate the effect of fiber reinforcement angle. As a result of the experimental study, it was determined that reinforcing the adhesives can increase the damage loads by up to 7%.
