An apparatus for drying granular resin material in a hopper including a first sub-system, including a membrane and a heater receiving drying gas from the membrane to be heated, the first sub-system supplying dried heated gas to a first portion of the hopper; and a second sub-system, including a mixing device and a heater for receiving drying gas from the mixing device to be heated, the mixing device inducing withdrawal of gas from the hopper and mixing the withdrawn gas with gas supplied from the first subsystem, the mixed gases being heated and supplied to a second portion of the hopper, the improvement comprising a gas separation membrane for separating inert gases from air supplied to the apparatus and providing the separated inert gas in the first subsystem; a heater for heating air supplied to the apparatus; and a thermostat for controlling the heater and thereby maintaining the supplied air at a selected temperature.

A thermoplastic prepreg includes a mat, web, or fabric of fibers and hollow glass microspheres that are positioned atop the mat, web, or fabric of fibers or dispersed therein. The thermoplastic prepreg also includes a thermoplastic polymer that is fully impregnated through the mat, web, or fabric of fibers and the hollow glass microspheres so that the thermoplastic prepreg has a void content of less than 3% by volume of the thermoplastic prepreg. The thermoplastic material is polymerized monomers and oligomers in which greater than 90% by weight of the monomers or oligomers react to form the thermoplastic material.
