Abstract

Unidirectional glass-epoxy composite has been tested under dynamic compressive loading conditions to study the different modes of failure and characterize them fractographically. Specimens of six fibre orientationsθ = 0, 10, 30, 45, 60 and 90° with respect to the loading axis were loaded on Kolsky bars at an average strain rate of 265 sec−1. The failure occurs on three different types of plane such that the fibre direction is preserved in all cases. Type A planes are tensile split planes and 0° specimens fail only in this mode. 10, 30 and 45° specimens shear on Type B planes by the combined action of normal and shear stresses. 60° and 90° specimens also fail by shear by the combined action of normal and shear stresses but on different types of planes called Type C planes. In these specimens the normal of the failure plane is found to make an angle lying between 55° and 70° with respect to the loading axis. The fractographs indicate intense matrix deformation and breaking up of fibre-matrix bonds for shear failure and comparatively clean fracture surfaces for tensile failure.
