Abstract
A heat curable, circular knitted fabric includes reinforcing and meltable resin fibers that can be cured to form a more rigid material form. In one embodiment, the fabric includes a core spun yarn, wherein the core may be made from glass, carbon, basalt, aramid or metal. The wrap surrounding the core may include resin type fibers such as Poly(p-phenylene sulfide) PPS, Polyetherimide (PEI), Polyether ether ketone (PEEK), Polysulfone (PES), Polyphthalamide (PPA), nylon, polyester, or polypropylene.
Claims21
An insulated exhaust component, the component comprising:
- a hollow tubular member;
- an insulating sleeve positioned around at least a portion of the hollow tubular member, wherein the sleeve comprises:
- a first sleeve portion comprising sleeve reinforcing fibers;
- and
- a second sleeve portion comprising a core spun yarn made, at least in part, from a heat curable material;
- wherein the insulating sleeve is configured to form a rigid, heat resistant, and non-flammable cover for at least the portion of the hollow tubular member when the sleeve is heated to a predetermined temperature.
A method of manufacturing an insulated exhaust component, the method comprising the steps of:
- providing a hollow tubular member;
- forming a rigid, heat resistant, and non-flammable cover positioned around at least a portion of the hollow tubular member, wherein forming the cover further comprises:
- providing an insulating sleeve positioned around at least a portion of the hollow tubular member, wherein the sleeve comprises a first sleeve portion comprising sleeve reinforcing fibers;
- and a second sleeve portion comprising a core spun yarn made, at least in part, from a heat curable material;
- cutting the insulating sleeve into a desired shape;
- wrapping and covering at least the portion of the hollow tubular member with the insulating sleeve;
- heating the hollow tubular member wrapped in the insulating sleeve to a predetermined temperature;
- and
- allowing the hollow tubular member and the insulating sleeve to cool, so that the insulating sleeve hardens maintains its shape about the hollow tubular member to form the rigid, heat resistant, and non-flammable cover.
A method of manufacturing an insulated exhaust component, said method comprising the steps of:
- providing a hollow tubular member;
- forming a rigid, heat resistant, and non-flammable cover positioned around at least a portion of the hollow tubular member, wherein forming the cover further comprises:
- providing an insulating textile positioned around at least a portion of the hollow tubular member, wherein the textile comprises a first sleeve portion comprising sleeve reinforcing fibers;
- and a second sleeve portion comprising a core spun yarn made, at least in part, from a heat curable material;
- cutting the insulating textile into a desired shape;
- placing the insulating textile into a mold;
- heating the insulating textile to a predetermined temperature;
- allowing the insulating textile to cool, so that the insulating textile hardens maintains its shape about the mold to form an insulating sleeve;
- and
- attaching said molded insulating sleeve to the hollow tubular member to form the rigid, heat resistant, and non-flammable cover.
