Abstract
This invention relates to methods of fabricating components of a pressure vessel using a dicyclopentadiene prepolymer formulation in which the purity of the dicyclopentadiene is at least 92% wherein the formulation further comprises a reactive ethylene monomer that renders the prepolymer formulation flowable at ambient temperatures and to pressure vessels that are fabricated by said methods.
Claims8
A method of fabricating a pressure vessel, comprising:
- providing a vessel liner;
- winding a filamentous material onto the vessel liner, wherein:
- the filamentous material is impregnated with a prepolymer composition prior to being wound onto the vessel liner, or
- the filamentous material is dry-wound onto the vessel liner and is then impregnated with a prepolymer composition;
- wherein:
- the prepolymer composition comprises dicyclopentadiene that is at least 92% pure, a reactive ethylene monomer and a curing catalyst, the reactive ethylene monomer comprising a weight percentage of the total monomer content of the prepolymer composition such that the prepolymer composition has a preselected viscosity at a preselected deposition temperature;
- and
- curing the impregnated, wound filamentous material to form a polymeric composite;
- wherein the reactive ethylene monomer comprises from about 1 wt % to about 10 wt % of the total monomer content;
- and
- wherein the reactive ethylene monomer is 5-hexylnorbornene, 5-decylnorbornene, or combination thereof.
