Abstract
A method of producing molded articles. The method uses a fibrous material and a first and second resin material. The first resin material is at least partially cured before being combined with the fibrous material and the second resin material. The molding material is inserted into a mold and processed to form a molded article by providing energy. The molded article is produced using less energy than would be necessary for processing a molding material which did not include a partially cured first resin material.
Claims13
A method of manufacturing a molded article comprising:
- a) providing a molding material comprising a fibrous reinforcement material, a first resin material and a second resin material, the first resin material being at least partially processed;
- followed by
- b) providing the molding material into a mold to form a molding;
- and
- c) processing the molding in said mold to form the molded article by providing energy input to the molding, the energy input for processing the molding to form the molded article being less than the energy input required for manufacturing the molded article from a molding comprising the same volume of said first and second resin material in which the first resin material is not at least partially processed.
A method of manufacturing a molding material comprising:
- a) providing a fibrous reinforcement material, a first resin material and a second resin material, the first and second resin materials being contact with said fibrous reinforcement material, the second fibrous reinforcement material and said first and second resin materials together forming a molding;
- and
- b) at least partially processing the first resin material before locating the molding material in relation to a mold, wherein the step of partially processing comprises at least part curing of the first resin material.
A molding material comprising a fibrous reinforcement material, a first resin material and a second resin material, the respective resin materials being in contact with said fibrous reinforcement material, the first resin material being at least partially processed prior to in-mold processing of the molding material.
