Composites are used in many different industries, from automotive to aerospace and from infrastructure to recreation. They're prized for their exceptional strength-to-weight ratio, high stiffness, durability, and resistance to corrosion, chemicals, and environmental exposures. These versatile materials also give engineers and designers great freedom to create new applications. The practically limitless material and processing possibilities can be a bit daunting — and that's why this guide can help sort things out.
