Latest Patents

One of Piascik's latest patents is for strain-detecting composite materials. This invention involves a composite material that includes a structural material and a shape-memory alloy embedded within it. The shape-memory alloy is designed to change its crystallographic phase from austenite to martensite in response to a predefined critical macroscopic average strain of the composite material. In a second embodiment, the composite material incorporates a plurality of particles of a ferromagnetic shape-memory alloy, which also changes its crystallographic and magnetic phases in response to strain. The method for forming this composite material involves providing the shape-memory alloy in its austenite phase, altering its size and shape, and combining it with the structural material at elevated temperatures.

Another notable patent is a system for repairing cracks in structures. This invention utilizes a first material with a known maximum temperature of operation, which is coated with a second material that has a higher melting temperature. When heated to its melting point, the coating flows into any cracks present on the surface of the first material, effectively sealing them.
