Title: MECHANICAL PROPERTIES OF DIFFERENT LENGTHS VIRGIN AND OUTDATED PRE-PREG FIBER COMPOSITES FABRICATED THROUGH WET LAYUP PROCESS
Abstract: Strength of fiber reinforced composites is relatively high compared to other materials; thus, there has been a drastic increase in the application of fiber reinforced composites in numerous industries. However, the cost of manufacturing long fiber reinforced composites is considerably high. The expense of the fibers can be significantly reduced with the help of recycled fibers which are obtained from the pre-preg outdated and waste generated by the aerospace industry. This will help solve an environmental issue, and also make the expensive fibers accessible to various other industries in a cost effective manner. This study investigated the techniques of receiving carbon fibers from outdated pre-preg composites, chopping the outdated fibers in different lengths, and fabricating new composites via wet layup process. In the same manner, virgin carbon and glass fibers were also fabricated using the same lengths and fiber-to-resin ratios for comparing the test results. The recycled fiber composites provided a little higher mechanical properties with the virgin fiber composites at much lower costs. These composites can be used in different industries, including sportive goods, construction supplies, automobile parts, boats, and blades at a reduced cost. While increasing profit for the companies, this process will also help clean up the environmental concerns of the pre-preg wastes that are produced by the aircraft industries.
