Abstract
This invention relates to a non-mold method of forming articles and to the articles themselves wherein various configured articles may be fashioned with conformable material which may be easily fabricated as by sewing, or heat, or sonic welding to form the basic shape of or modular elements of a completed article, and wherein a thermal setting, flowable polymer or the like is introduced into the space between layers of the conformable material to thereby form the completed article or modular element.
Claims10
A method of forming composite objects comprising the combination of:
- a) forming two patterns of conformable material representative of a final shape of the object to be formed;
- b) sealing said two patterns together along the major periphery thereof to thereby form an intermediate space;
- c) introducing a flowable polymer into said intermediate space and allowing said flowable polymer to polymerize into a solid;
- said two sealed patterns unsupportedly providing said final shape of said object.
- d) obtaining the formed object whereby said conformable material and solid polymer are integral.
A method of forming a modular composite object comprising the combination of forming two layers of conformable material representative of the modular shape of the element to be formed;
- sealing the two layers along a major periphery thereof to thereby form an intermediate chamber;
- introducing a thermal setting flowable polymer into said chamber and allowing said flowable polymer to polymerize into a solid;
- said two sealed layers unsupportedly providing said modular shape of said element and obtaining the formed modular element whereby the layers of material and said polymer are integral with the outer surface of said conformable material which forms a part of the modular element itself.
