This PowerPoint presentation provides an introduction to basic composite repair training. It discusses the history of composites, including their early uses in ancient civilizations and development during World War 2. The document defines composites as materials made of two or more components combined to produce desired properties. Fiber reinforcements are embedded in resin matrices. Applications of composites include bicycle frames, bridges, and naval vessels due to advantages like design flexibility, strength to weight ratio, and corrosion resistance. However, composites also have disadvantages such as high costs, difficulty inspecting internal damage, and potential health hazards.
