| Abstract | ||
| This work is carried out with using of unsaturated polyester resin mixed with natural rubber (90%-10%) to compose a polymeric blend. This polymeric blend is the matrix, which reinforced with several types of reinforcements (Al powder, Al wires, and glass fibers G.F) with a volume fraction of 20%.Hand Lay-up method is used in fabrication of samples of research. Four samples are prepared: - 1. Blend (Unsaturated polyester + Natural Rubber). 2. Blend reinforced with hybrid (Al wires + glass fibers). 3. Blend reinforced with Al wires. 4. Blend reinforced with Al powder. Several mechanical tests are carried out on these samples, and these are:- hardness test, compression test, and impact test.These tests are carried out on samples under the influence of normal conditions (room temperature) and after immersion of all samples in the chemical solutions (KOH, HNO3, and Na2CO3) for 1, 2, and 3 months. The normality for all these chemical solutions is 1N.Results show that highest values of impact strength obtained with samples of blend reinforced with hybrid reinforcements (Al wires + glass fibers) at all conditions of test (room temperature and after immersion in chemical solutions).While, highest values of compression strength obtained with samples of blend which is composed from (Unsaturated polyester + Natural Rubber) at all conditions of test.Finally, highest values of hardness obtained with samples of blend reinforced with Al powder at room temperature. The tests results are affected negatively by all of the chemical solutions, but the base solution KOH is the most effective solution. | ||
