ABSTRACT:
Novel glass fiber strands of relatively short lengths are disclosed in which the strands are formed of a consolidated bundle of glass filaments. The filaments making up the consolidated strand have external diameters of 0.0003 to 0.003 inch (0.0016 to 0.076 millimeters) and 10 to 65 percent of their volume is hollow. The filaments are further sealed at each of their ends in the short lengths of consolidated strand.
