This research includes the preparation of polymers mixtures consists of resins
(Unsaturated Polyester with Polyurethane) (UP+PU), where the optimal mixing
ratio has been selected on the basis of the best impact strength. It is found that the
mixing ratio with percentage (60% Polyester+40% Polyurethane), where it has
been used to prepare the samples. The mechanical tests have been performed on the
prepared samples; in addition the effect of increasing the temperature (22±2 °C
(R.T.), 35±4°C, 50±4 °C) has been studied on the samples. A four samples where
prepared from the polymers mixtures using the above mentioned mixing ratio by
using the method of hand casting technique; these samples are: polymers mixture
consisting of (UP+PU), added to it the micro cotton powder with weight ratio (2%)
once and for copper by weight ratio (39%) with volumetric fraction of copper (5%)
again, as well as composite material was prepared from the same polymers mixture
adding to it micro cotton powder filling and chips together in the same weight
ratios mentioned earlier. Some mechanical tests were conducted include: (Flexural
strength and Tensile strength). A sample of the four polymers mixtures have been
examined using the Scanning Electron Microscopy (SEM), and study the effect of
adding reinforcement materials, and also study the topography of the surface of
each sample and the knowledge the fine structure for each mixture. Results showed
that the reinforced blends with micro cotton powder and copper (UP+PU+MC+Cu)
possess better mechanical properties of Flexural strength and Tensile strength, also
it has all tests are affected by temperatures.
