Push-in test

Microindentation or push-in test In this experiment, a micro-indentor is used to push the fibre into the matrix. Its major advantage is that it can be applied to fibres in a polished section of a fibre composite without the need for special specimen fabrication. The interfacial shear strength is related to the displacement of the fibre into the matrix la and the appropriate load P ... 

While there are seve tests that can be done to determine the interfacial shear stress [4], one of the better known is fiber push in testing [4,6]. It is known fi om the work of others [8], that the sample preparation for this is very difficult. Part of the work for this paper is to show a different method for sample fabrication that allows a larger and more uniform sample to be made for this test.
