Abstract

One of the most important failures that occur during the forming of laminated composite materials is shear failure. Interlaminar shear strength is examined to determine this mechanism of damage. In this study, bending test via the short beam method was applied to thermoplastic composite laminates with two different compositions. It was aimed to analysis on the effects of the glass fiber architecture types on shear properties of the thermoplastic composite laminates. Both types of composite laminates have 3 mm thickness, the matrix element is Polypropylene and the reinforcing element is glass fiber. The first material has a fiber ratio of 60% and a continuous fiber stacked at 0/90 in its structure. The fiber content of the second material is 38% and it contains both chopped and woven continuous fiber. The interlayer shear properties of two kinds of composite laminates containing reinforcement elements in different types were compared. In addition, failure situations were examined by performing macro imaging. The shear strength of the composite laminate containing chopped fiber was higher than the composite material with high continuous fiber weight ratio.

Özet

Kompozit levha malzemelerin şekillendirilmesi sırasında meydana gelen en önemli hasarlardan birisi de kayma hasarıdır. Bu hasar mekanizmasının belirlenmesi için tabakalar arası kayma direnci incelenmektedir. Bu çalışmada, iki farklı kompozisyona sahip termoplastik kompozit levhalara kısa kiriş metoduyla eğme testi uygulanmıştır. Cam elyaf mimarisinin termoplastik kompozit levhaların kayma özellikleri üzerindeki etkilerinin incelenmesi amaçlanmıştır. Her iki tür kompozit levha da 3 mm kalınlıkta olup, matriks elemanı Polipropilen ve takviye elemanı cam elyaftır. Birinci malzemenin yapısında 0/90 dizilmiş ve %60 oranda sürekli elyaf bulunmaktadır. İkinci malzeme ise % 38 oranda hem kırpılmış hem de dokunmuş sürekli elyaf içermektedir. Farklı biçimlerde takviye elemanı içeren iki tür kompozit levhanın tabakalar arası kayma özellikleri karşılaştırılmıştır. Ayrıca, makro görüntüleme yapılarak hasar durumları incelenmiştir. Hibrit elyaf içeren kompozit levhanın kayma dayanımı, kütlece sürekli elyaf oranı fazla olan kompozit malzemeye göre daha yüksek çıkmıştır.
