| Abstract | ||
| This studying deals with the study of the effect of fiber volume fraction of the carbon, glass and Kevlar fibers and their orientation on the properties of Hybrid composite material. Different percentages of carbon, glass and Kevlar fibers were used to reinforce the matrix material (unsaturated Polyester). The fibers arranged in two methods according to the direction of the thermal flow. In the first method the fibers were parallel to the direction of the thermal flow, while the second method was perpendicular. The thermal conductivity measured by using Leeś disk. The experimental and theoretical results proved that the value of the of thermal conductivity increased with increasing the fiber volume fraction of the carbon ,Kevlar-49and glass and then reduced for Hybrid (H7and H8) for both arrangement parallel and perpendicular because do not hah carbon fiber. The thermal conductivity of parallel orientation had the highest value, while the carbon factor was the best. The experimental results of thermal conductivity for parallel arrangement indicated that the hybrid (H6) had maximum value 3.40 W/m.k and for perpendicular was 0.245 W/m.k for hybrid (H3). | ||
