Since the 1950s, composite engineering has revolutionized the aerospace industry with lighter materials renowned for their strength. Composite materials consist of fibers (typically glass, carbon, or Kevlar) that are suspended in a matrix of resin (often epoxy, phenolic or polyester). Advantages of composites include resistance to corrosion, temperature, and weather, and they can even be molded into most shapes. By looking back on the last two decades of growth in aerospace composites, Mentis Sciences previews what the next five years have in store for our industry.
