Effect of thermal shock on flexural analysis of composite laminated simply supported rectangular beams

الملخص EN

The effect of thermal shock on bending test of composite laminated simply supported rectangular beam is investigated experimentally and numerically.

In experimental part, three types of fiber reinforcement [Matt fiber glass (600 kg / mP3P) and Random fiber glass (450 kg / mP3P, and 300 kg / mP3P)] are used with polyester resin.

The flexural bending test with and without thermal shock load on top or bottom surfaces of the specimen are investigated.

The heating and cooling temperature applied are (70CPoP and-30CPoP) respectively.

In numerical part, the ANSYS software is used to compare the results with the experimental work.

Effect of volume fraction is also investigated.

The results showed that, the increasing volume fraction causes decreasing the maximum deflection.

Random fiber glass (300 kg / mP3P) composite materials gives minimum deflectionwhen compared with other two types of fiber for same volume fraction.

The heating on top surface and cooling on bottom surface of the beam causes decreasing in maximum deflection.

The cooling on top surface and heating on bottom surface of the beam causes increasing in maximum deflection.

Good comparisons are found between experimental data and numerical work.
