Researchers at Purdue University have developed a phase transforming cellular matrix (PXCM) for use in non-pneumatic tires (NPT) and runway tiles. Compared to traditional cellular structures, Purdue's solution offers superior mechanical performance, self-healing, and increased fuel efficiency for vehicles and aircraft. NPTs made from this PXCM are capable of transitioning from off-road to highway conditions without the need to change tire pressure. Applications of this technology are in the defense sector or any industry where it is critical to have high durability tires or surfaces that minimize wear and maintenance in varied conditions.

Advantages

NPTs made from this material have increased longevity and decreased wear

Capable of automatic change from off-road to highway conditions

No need for air like conventional tires

As a runway mat, significantly more durable than current solutions



Applications

Military/defense

Automotive and offroad vehicles

Aviation



Technology Validation:

This technology has been validated through testing alternating panels of PXCMs to construct mats. In testing, these mats were capable of withstanding over 5000 landing and take-off cycles over a 60 day period while showing no signs of failure. Current conventional runway mats fail at approximately 1500 cycles.
