A method and product for improved ceramic fiber reinforced and/or filled thermoplastic and/or thermosetting resin systems utilizes ceramic fiber material which is first etched and then silanated using an organo-functional silane. The etching of the ceramic fiber may be performed utilizing hydrofluoric acid, acidulated phosphate fluoride or the equivalent thereof. The term ceramic fibers is used broadly to include all types of fibers which are made from substantially pure or pure silica, various silicates, metal oxides and other fibers, such as carbon, which are coated or provided with a silica treatment on their surface. |
