Abstract

Fiber reinforced hollow film forming material microspheres 17 made from a fiber and film forming material composition are described. The fiber reinforced hollow microspheres 17 are used to make shaped and molded articles and to make insulation materials. The fibers can be made from ceramic materials, glass, metal, metal glass and plastic. The reinforcing fibers can be one-half to five microns in diameter and five to one hundred microns in length.
