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.https://etj.uotechnology.edu.iq/article_26458_0abc5c111d85639e893659d19b885eb0.pdf
