Effect of Heat on Bending Behavior of Composite Material

ABSTRACT This research was carried out to study the effect of heat on bending behavior of composite material with three types of composite beam (simply supported beam, fixed and cantilever beam). Multi-layer samples of glass fiber-polyester composite with 0?/ 90? and 45? /-45? orientation were tested. The experimental results showed that increasing the temperature has an effect on the deflection at the same load; also the change in the orientation of lamination of the fiber glass has an effect on the deflection values. Moreover, the results showed that the specimens with the 0?/ 90? have a deflection less than the orientation (45?/-45?). On the other hand, assessment of these results is carried out analytically by using (ANOVA analysis). Keywords: Composite materials, bending behavior, Regression analysis, ANOVA.
