Abstract

A multi-layered composite mold structure ( 10 ) is provided. The multi-layered composite mold structure ( 10 ) comprises a multi-layered member including (a) at least one metal heating layer ( 11 ); (b) at least one metal heat distribution layer ( 13 ); (c) at least one laminate composite layer ( 12 ); and (d) a surface layer ( 14 ). A process for preparing the multi-layered composite mold structure is also provided.

First claim

What is claimed is:

1. A composite mold structure comprising a multi-layered member including:
(a) at least one heating layer;
(b) at least one metal heat distribution layer;
(c) at least two laminate composite layer; and
(d) at least one surface layer comprising a quasi-isotropic laminate material, wherein the at least one metal heat distribution layer is disposed under the surface layer and the at least one metal heat distribution layer distributes heat uniformly throughout the surface layer of the composite mold structure and wherein the at least one heating layer is embedded between at least two said laminate composite layers;
and wherein the surface layer comprises fabric materials impregnated and cured with thermosets or thermoplastic materials.

2. The composite mold structure of claim 1 , wherein the at least one heating layer comprises heating wire, heating tube or heating mat encapsulated with cured laminate composite.

3. The composite mold structure of claim 1 , wherein the at least one metal heat distribution layer comprises a perforated metal plate, sheet, foil or combination thereof or a non-perforated metal plate, sheet, foil or combination thereof.

4. The composite mold structure of claim 3 , wherein metal plate, sheet, foil or combination thereof comprises steel, cooper, aluminum or metal alloys.

5. The composite mold structure of claim 3 , wherein the perforated metal layer is a mesh type metal layer.

6. The composite mold structure of claim 1 , wherein at least one of the laminate composite layer comprises fiber or fabric materials impregnated and cured with thermosets or thermoplastic materials.
