Study of thermal characteristics of a composite specimen experimentally and by using finite element method

الملخص EN

This research deals with the study of the effect of fibers volume fraction and fibers orientation on the thermal conductivity and wall surface temperatures for composite specimen in form of Lee’s disk by using experimental work and finite element technique.

The results show that the thermal conductivity increases with increasing fiber volume fraction of the composite specimen, and in the longitudinal direction is larger than in the lateral fiber direction.

The experimental results indicated that the largest value of the thermal conductivity for the composite specimen was (0.611 W / m.

°c) at (Vf = 40 %) in the longitudinal direction, while the lowest value was (0.195 W / m.

°c) at (Vf = 10 %) in the lateral direction.

Also the results show that the maximum difference for the thermal conductivity between the experimental work and finite element method was (7 %) at (Vf = 10 %) in the lateral direction while the minimum value was (3.5 %) at (Vf = 40 %) in the longitudinal direction.
