METHOD OF THERMAL SPRAY COATING FIBER-REINFORCED COMPOSITE MATERIALS
First Claim
1. A coated fiber-reinforced composite workpiece comprising:
- a fiber-reinforced composite substrate including fibers distributed in a matrix; and
a thermal spray coating applied to the substrate, the coating being bonded directly to the fibers via diffusion of the coating into the fibers, the formation of an intermediate compound at an interface of the coating and the fibers, or both.

Abstract
A method of coating a fiber-reinforced composite material includes providing a fiber-reinforced composite workpiece, treating a surface of the workpiece to remove at least a portion of a polymer matrix and to expose fibers to a treated surface of the workpiece, and coating the treated surface of the workpiece using a thermal spray coating process. The treatment can include laser ablating or applying a peel ply process. The method yields a coated fiber-reinforced composite workpiece with the coating being bonded directly to the fibers via diffusion of the coating into the fibers, the formation of an intermediate compound at an interface of the coating and the fibers, or both.
