Composites Technology

Students may pursue a certificate or ATA degree in composites technology to prepare for employment in the automotive, sports, aviation and marine industries. The overall program is designed for maximum flexibility, and may be pursued on a full-time or part-time basis. In addition to the Student Core Learning Outcomes, the Program Specific Outcomes include: • Solve technical mathematical problems (such as fiber resin ratio) • Learn basic hand skills for the layup of composites materials using fiberglass, carbon fiber, epoxy and polyester resin • Design molds and forms for the layup of fiberglass and carbon fiber materials • Build and vacuum bag composite materials for room temperature cure and oven cure materials • Create projects in composite materials showing how surface energy is increased and decreased • Design for producibility and manufacturing ease • Document technical activities in written and verbal reports • Be prepared for successful employment
