In recent years, composites have replaced aluminum for many aerospace applications because of their superior specific strength and stiffness properties. First developed for military applications, composites now play a significant role in a wide range of current-generation aerospace systems.

NIAR’s Composites and Advanced Materials Laboratory plays a major role in the aviation industry. Researchers and technicians in the Composites Lab perform lay-up and bonding operations and work directly with researchers in the Structures & Fatigue Laboratory to understand the effects of heat, moisture, contamination and repairs on advanced materials. The lab also provides regularly scheduled hands-on training workshops.
