Composites are materials made up of individual components, whose combined physical strength exceeds the properties of either of them individually. In the case of composite laminates, there are two basic elements involved: fibrous reinforcement (such as Fiberglass or Carbon Fiber) and resin. These two elements are not meant to be used exclusively—they are meant to be combined. In doing so, they bond mechanically and chemically to form a hard, laminate part that cannot be reformed.Think in terms of a boat. Many boats are made using fiberglass, which begins as a textile—like a long piece of fabric that comes on a roll. Fiberglass is laid into a mold that will create the boat's hull. A resin, in liquid form, is catalyzed and applied to the fiberglass in-mold. It will cure and bond to the fiberglass chemically, producing a great deal of heat (called thermosetting). Multiple layers and various techniques are involved, but your end result is the boat.
Composites, like the boat, are popular for a number of reasons, but largely for their combined high-strength for low-weight ratio. In general, they can be tailored to suit different applications, and formed to unique and complex shapes. They are also popular for a superior resistance to most environments and can be used by most fabricators without significant investment.
We'll look at a number of reinforcements and resins from which to choose. Lets take a look at actual Fiber and Resin product examples, for you to better familarize yourself with the composite industry.
