This is the first industry to realize the benefits of composite materials. Glass, carbon, and Kevlar fiber composites are frequently used in designing aerospace parts for airplanes, rockets, and missiles, which all fly higher, faster, and farther with the help of composites. The fin boxes, flaps, horizontal/vertical stabilizers, wing skins and other structural components are being designed with the composites which help in lowering down the weight of the structure [14]. A mass reduction of 20 to 35% can be achieved using composite materials. This weight saving in fighter planes enhances the payload efficiency as well as the missile range. In spacecrafts, the composites help in reducing its weight which assists in maintaining the dimensional stability in low earth orbit, where temperature variate in the range from -100 to +100 °C. Carbon epoxy composite laminates provides zero coefficient of thermal expansion in space structures including tubular truss structures, facesheets for the payload baydoor, antenna reflectors, etc.
