Abstract

Researchers have studied the effect of reinforced powder on the behavior and properties of a composite materials structure. These investigations included the effects of reinforcement by fiber and powder materials. This work studies and investigates experimentally the effect of various types of powder materials and volume fraction on the buckling plate structure. In addition, the FEM numerical technique was employed to compare with the experimental buckling results which were evaluated to give an agreement for the results. Experimental work was conducted to evaluate the buckling behavior of a plate, the first test s were performed on the manufactured composite materials to evaluate the mechanical properties, and finally the plate structure was tested to investigate the critical buckling load with the effect of various parameters of powder materials. The results showed that; using short fibers as reinforcement gave an improvement on the mechanical properties and increased buckling resistance as compared with the powder. The maximum discrepancy between the experimental and numerical results was (9.54%).
