ASPECTS CONCERNING TO THE MECHANICAL PROPERTIES OF THE GLASS / FLAX / EPOXY COMPOSITE MATERIAL

Abstract

The first of all, the paper focus on the aspects concerning to the structure of the hybrid composite tested, the stacking sequence of the layers reinforced either with glass fabric or with flax fabric. The mechanical behaviour of the glass / flax / epoxy composite material was analyzed by using tensile test and flexural test (bending). The work describes the mechanical tests and the equipment used. After the statistical processing of the experimental data recorded on both weft and warp directions in case of all specimens tested, the average values of the following properties are computed: Young’s modulus E in tensile test, tensile normal stress at failure, tensile normal strain at failure, Young’s modulus in bending, flexural normal stress at failure, strain energy both tensile test, and bending. Finally, the results are compared with the ones corresponding to a similar composite material that contains the same number of layers reinforced only with flax fabric.
