System for preparing glass fiber pellets |
摘要 |
A system for making densified glass fiber pellets from chopped segments of multi-filament glass strand is described. The densified pellets may be advantageously produced by hydrating chopped glass strands and then pelletizing them by tumbling in a rotary drum, and densifying the resulting pellets by tumbling in a rotating zig-zag or undulating tube for a period of time sufficient to increase their density but insufficient to degrade the fibers to a point where composite articles formed from such pellets have lower tensile or impact strengths than comparable composite articles formed from unpelletized strand segments.
