Researchers at the Massachusetts Institute of Technology are testing an advanced new composite that overcomes the major shortcomings of such materials that are difficult to detect after damage.
The composite material is tough and lightweight, and is well suited for use in the aerospace industry, but composite materials are prone to failure under the various pressures experienced by the aircraft. Damage to metal parts is often traceable (such as cracks or dents), but parts made of composite materials may look intact even if they are internally damaged.
Thermal imaging technology is often used to detect interruptions in normal heat flow patterns, requiring large, specialized equipment to heat the surface of the aircraft, and then using thermal imaging cameras or goggles to check for heat flow, making it easier and faster to detect faults.
