Abstract
A sizing composition includes a texturing agent, a film-forming agent, and organic particles dispersed therein. A glass fiber strand is formed from a plurality of individual glass fibers coated with the sizing composition. A thermoplastic composite material includes such glass fiber strands.
Claims18
A sizing composition for glass fibers, the sizing composition comprising by weight of dry extract solids content:
- 10 to 90% by weight of polymer particles;
- 0.1 to 6% by weight of a texturing agent;
- 5 to 60% by weight of a film-forming agent;
- 0.1 to 6% by weight of at least one compound selected from a surfactant, a plasticizing agent, a dispersing agent, and mixtures thereof;
- 0.1 to 10% by weight of a coupling agent;
- and
- 0 to 15% by weight of at least one additive.
