A STUDY OF EFFECT OF REINFORCING FIBERS DIRECTION FOR THE POLYMERCOMPOSITES ON THE THERMAL CHARACTERIZATION USING COMPUTERMODELING

The study was created using ANSYS 5.4 the Physical CAD tool to find out the effect of fiber direction on thermal characterization for tow types of the polymer composites. One was the epoxy reinforced with Glass fibers composite (EGF), the other was the Polyester reinforced by the same type of fibers (PGF). The fibers angled with tow angles 00 and 450 with pivot of each type of the composites. The loads and boundary conditions (B.C) was applied as different temperatures. The study included temperature distribution, thermal flux and thermal gradient in which obtained directly from the package. The thermal conductivity withal was calculated from the results. The analysis showed that the temperature distribution is almost constant for all models, the thermal flux was 1743 (J/S.m2) for the EGF composites with 00 and 1494 (J/S.m2) for the 450, thermal gradient was 3134 (K0/m) for 0 0 and 4187 (K0/m) for 45 0. For PGF composites the values of thermal flux was 1799 (J/S.m2) for 00 and 1505 (J/S.m2) for 450, the thermal gradient was 3112 (K0/m) for the 00 and 4187 (K0/m) for 450. Thermal conductivity obtained from the previous results and the highest value was 0.578 (W/K0.m) for PGF 00, followed by 0.556 (W/K0.m) for EGF with the same angle of fibers. Other hand the other composites EGF and PGF with 45 0 had a lower values for thermal conductivity which were both about 0.36 (W/K0.m), for that reason we conclude that the last tow types (with 450 angle) were preferred to use in applications as water tanks or other thermal insulation systems.
