PROCESS OF MAKING A SIZED AND RESIN-COATED FIBER

A method of making a sized and resin-coated fiber tow for use in a fiber reinforced composite, the method comprising the steps of providing a fiber, contacting at least a portion of the fiber with a sizing slurry to form a sized and resin-coated fiber, the sizing slurry comprising 0.1-25% by weight...

Zusammenfassung:A method of making a sized and resin-coated fiber tow for use in a fiber reinforced composite, the method comprising the steps of providing a fiber, contacting at least a portion of the fiber with a sizing slurry to form a sized and resin-coated fiber, the sizing slurry comprising 0.1-25% by weight of a sizing agent and 20-80% by weight of a matrix-resin powder in a solvent, based on the total weight of the sizing slurry, wherein the total solid content, including the sizing agent and the matrix-resin powder, of the sizing slurry is greater than 30 wt.%. The method further comprising drying the sized and resin-coated fiber at a temperature below the melting point of the matrix-resin powder, thereby forming a dried sized and resin-coated fiber and winding the dried sized and resin-coated fiber onto a spool.
