Damage behaviors of glass fabric honeycomb Sandwich composite materials under static loading
Sandwich Composite structures have been widely used in the fields of aircrafts. Investigations of the mechanical properties of sandwich composite structures play a vital role in deciding their applicability in various engineering fields. The objectives of this work are fabricating the sandwich composite structures with honeycomb/woven glass fabric using Vacuum Assisted Resin Transfer Molding. In order to evaluate the internal and external damage resulting under (three point bending, compression, tensile loading) tests using product computerized universal testing machine. The load-displacement curves were obtained to characterize the failure mechanisms of sandwich composite structures. The failure modes were studied, it was observed that in the start matrix crack after that delimitation between two layers, finally the final failure occurred when the face sheet failure.
