Abstract

The fiber-matrix interface plays a major role in the mechanical properties of composite materials which mainly depends on the ability of transferring load from matrix to fiber during loading condition. Many researchers has concluded that the strain energy transfer process influence properties when composites subjected to quasi-static indentation. This research work deal with effect of rate of indentation in different E glass / epoxy composite laminates hybridized with E glass powder of various proportions, it is also studied that how the fiber orientation will influence the E glass powder percentages during loading It is observed that as the powder percentage is increased the strength of the laminate is reduced but in some cases as illustrated in the figures, powder addition will have different effect in laminates with different fiber orientation
