|Researchers at Purdue University have developed a new phase transforming cellular matrix (PXCM) based panel design to develop durable, light-weight runways for aircraft takeoff and landing. A runway was created using PXCM textiles and in testing showed no signs of failure in over 5,000 cycles with varying dynamic loads over the course of 60 days. Current runway technology only lasts 750-2,056 passes. The PXCM textiles fine-tuned by Purdue researchers exhibit excellent elasticity, are assembled through a simple hexagon laying pattern, and mimic foam in porosity to allow for minimal weight.
Technology Validation: This technology has been validated by subjecting the paneling to a hard-brake test with a 4-ton truck. After five rounds of testing, minimal change in the structure of the panels was observed. The panels were also subjected to 50 cycles of bending tests which showed no material failures, and the material recovered from the repetitive deformation.
-Lightweight, durable construction
-Easily connected into structures or sheets
-Can absorb shocks and unexpected high loads (e.g., aircraft coming at a higher vertical velocity than those recommended, etc.). Increase fatigue life.
-Deployable aircraft runways
-Landing pads for other flying objects (drones, helicopters, etc.).
-Rapidly deployed structures/buildings (e.g., for disaster emergencies, etc.)
