Composite engineers utilize composite materials, such as resins, carbon fiber composites, and glass fiber-based materials, to design structures and buildings. Composite materials are made by combining two substances with different properties that, when put together, produce a more durable product. These composites are used to build bridges, buildings, spacecraft, imitation granite, and other structures that need to withstand demanding situations. As a composite engineer, you specialize in how to utilize these materials to design projects to meet client needs. To become a composite engineer, you need a bachelor’s degree in engineering with a specialization in mechanical or structural engineering. Most positions require a minimum of five year’s experience with AutoCAD and a proven track record of successful projects.
