The invention also provides a method of manufacturing a tool, a method of moulding articles using such a tool, and elastomeric material for use in forming a tool. One particular application of the tools of the present invention is in the formation or manufacture of moulded articles using curable, resinous composite materials.
Claims16
A moulding tool, the tool comprising a tool body formed of foamed material, a resinous material on the tool body and elastomeric material located between said tool body and resinous material to inhibit the movement of resin from the resinous material into the tool body and to provide a compliant layer or interface between the tool body and the resinous material, wherein the elastomeric material comprises a fluoroelastomer.
A method manufacturing a molding tool, the method comprising forming a tool body of foamed material, applying an elastomeric material to be between the tool body and a resinous material of the tool such that the elastomeric material acts to inhibit the absorption of resin from the resinous material into the tool body and to provide a compliant layer or interface between the tool body and the resinous material, wherein the elastomeric material comprises a fluoroelastomer.
