Four different ratios of composites were prepared by varying the
wool glass, at different additive weight percentages (0, 0.2, 0.4, 0.6 wt. %)
in order to study the effect of glass wool reinforcement on mechanical and
chemical properties of GW-reinforced polyester composites. The vacuum
bagging technique was adopted for the fabrication of hybrid composite
materials. Afterword many mechanical properties as hardness, impact
resistance, and compression resistance for these hybrid composites were
evaluated according ASTM Standards. The mechanical properties were
improved as the fibers reinforcement content increased in the matrix
material. The chemical properties were improved as increased the weight of
glass wool. The chemical and mechanical properties have been increased
for maximum value when glass wool fiber has reached 0.6% wt.
