N2 - Carbon fiber reinforced composites (CFRP) exhibit light weight, high stiffness and strength along the direction of reinforcement. They also have good corrosion resistance and low thermal expansion coefficient, compared to metals. However, they are more sensitive to the impact of solid particles (e.g. sand particles) and droplets (e.g. rain droplets) which have a critical impact on their reliability in service. Various solutions are already used to prevent erosion of CFRPs (e.g. metallic caps, organic paints, tapes), but these do not demonstrate sufficient durability and noticeably increase the components weight. Solutions under development involve sol-gel and thermal sprayed coatings. However, the polymer matrix's low surface energy and low chemical reactivity proved to be an issue, when bonding the metallic or ceramic coating to the polymer surface. Previous works carried out in this laboratory have shown that a way to improve coating deposition was to remove the superficial layer of polymer to favor the coating formation on the carbon fibers. This can be done by using a chemical etching that removes the superficial resin. This study aims at understanding the effects of this chemical etching on the composite surface and on the formation of plasma-sprayed ceramic coating on the composite.
