Determination of interlaminar shearing strength of fiber composite materials by tensile shear test

Abstract

Delamination is the most frequently arising failure mode of the group structures. Production lacking and/or the errors developing with the later employment can lead to delamination. In this work the interlaminar shearing strength was examined by fiber composite materials from glass and carbon reinforced plastics by tensile shear test. In the production of the test bars, autoclave method used. The failure can occur either within a layer or between the layers. The latter is to be feared above all if the monolayers are not integrating manufactured, but stuck together later with one another. in order to eliminate the not-avoiding influences occuring with the tensile shear test, the adhesive strength of the fiber composite materials at double-sided samples was determined.
