Abstract: A composition of matter has a fiber structure impregnated with a polymer, the polymer having dispersed functionalized particles chemically bonded to the polymer, wherein the functionalized particles contain one of either groups same as a precursor of the polymer, or groups reactive with a precursor. A composition of matter has a fiber structure impregnated with cured epoxy resin having dispersed functionalized particles chemically bonded to the cured epoxy, wherein the functionalized particles contain one of either groups same as the epoxy resin, or groups reactive with the epoxy resin.

Abstract: A method of recycling fiber reinforced polymers includes grinding used fiber reinforced polymers material to produce ground particles, functionalizing the ground particles to produce functionalized particles, dispersing the functionalized particles into a base resin, dispensing the resin with functionalized particles into one or more layers of continuous fiber mats, molding the resin with functionalized particles and the continuous fiber mats into a form of a desired part, and curing the form to produce the part. The used fiber reinforced polymer materials may be carbon fiber reinforced polymers or glass fiber reinforced polymer materials.

Abstract: A heat switch has a first contact, a plug of thermally conductive material, and a mechanical actuator attached to the plug of thermally conductive material, the mechanical actuator arranged to move the plug into contact with the first contact in a first position and to move the plug out of contact with the first contact in a second position responsive to an input signal.

Abstract: A thermal switch has a first substrate, a thermally conductive region on the first substrate, a thermally insulative region on the first substrate adjacent the thermally conductive region, a second substrate arranged adjacent the first substrate, a droplet of thermally conductive liquid between the first and second substrate adjacent the thermally conductive region and the thermally insulative region, and an actuator arranged on one of the first or second substrates to cause the droplet to move between the thermally conductive region and the thermally insulative region on the first substrate.
