This PowerPoint presentation provides an introduction to composite materials. It discusses the history of composites, including early uses in ancient civilizations and advancements during World War 2. It defines composites as materials made of two or more materials combined to produce desired properties. Fiber reinforcements are embedded in a resin matrix. Examples of composite applications include bicycle frames, bridges, and naval vessels. Advantages include design flexibility, strength to weight ratio, corrosion resistance and fatigue resistance. Disadvantages include high costs, difficulty inspecting internal damage, and potential health hazards from thin fibers.
