Abstract
A method of manufacturing a moulded article and a moulding material suitable therefor comprising the steps of providing a moulding material comprising a fibrous reinforcement material, a first resin material and a second resin material, the first resin material being at least partially processed; providing the moulding material in relation to a mould to form a moulding; and processing the moulding to form the moulded article by providing energy input to the moulding. The energy input for processing the moulding to form the moulded article is less than the energy input required for processing the moulded article from a moulding.
Claims20
A method of manufacturing a moulded article comprising:
- a) providing a moulding 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 moulding material in relation to a mould to form a moulding;
- and
- c) in-mould processing the moulding to form the moulded article by providing energy input to the moulding, the energy input for processing the moulding to form the moulded article being less than the energy input required for manufacturing the moulded article from a moulding comprising the same first and second resin material in which the first resin material is unprocessed.
A method of manufacturing a moulding material comprising:
- a) providing 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;
- and
- b) at least partially processing the first resin material before locating the moulding material in relation to a mould, wherein the step of partially processing comprises at least part curing of the first resin material.
A moulding 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-mould processing of the moulding material.
