Abstract
Multi-shape products of the present disclosure comprise two components: a matrix component and a fiber component that is embedded or otherwise disposed in the matrix component. The matrix component exhibits certain shape memory properties. The fiber component interpenetrates the matrix component to facilitate fixing of the multi-shape product in various temporary shapes.
Claims18
A multi-shape product, comprising:
- a first component forming a matrix and comprised of a shape memory polymer having a shape memory recovery temperature;
- a second component forming a fiber network having a plurality of fibers, a plurality of nodes where fibers contact each other, and a plurality of interstitial voids between the fibers, wherein said fibers comprise a polymer having a transition temperature that is within 50 degrees Celsius of said shape memory recovery temperature;
- and
- wherein said fiber network is embedded in the matrix so that said matrix fills the plurality of interstitial voids.
