    • Abstract:
      The article focuses on the use of composite materials in the manufacturing of airplanes. Composite materials are being increasingly used in airplanes as they are light and tough. Plane manufacturers are replacing metal parts in aircrafts with composite materials. But composite plastics can be weakened without any visible sign at the surface. According to Philip Irving, an expert in aviation damage tolerance at Cranfield University in Bedfordshire, England, if composites used in airplanes fail, they can cause damage to an aircraft. There is a need to conduct routine maintenance checks to avoid accidents due to damaged parts. INSETS: Stopping the cracks;New clues?.
