Composite insulation system
Embodiments of the present invention provide a self-molding composite system for insulation and covering operations. The self-molding composite system may be cured to form any desired shaped for insulation and covering operations. The composite system comprises one or more layers that may create a rigid layered composite when cured. The one or more layers of the composite system may include a base layer that is a braided, knit, or non-woven fiber based substrate, an interstitial matrix layer, and customizable top coat. The customizable top coat may be a solvent based polymer solution that includes various additives that may include color pigments, additives for additional abrasion protection, additives for thermal protection, and/or additives for creating various textures or visible appearances to the composite system.
1. A method for producing a composite insulation system, the method comprising:
providing a braided tape;
wrapping the braided tape around an exhaust component so that the braided tape conforms to the exhaust component;
wrapping and tucking ends of the braided tape into adjacent wraps of the braided tape;
positioning a self-molding fiber cover comprising an elastic structure over the braided tape to provide compression around the exhaust component;
providing a composite matrix solution comprising a dispersion of ground thermoplastic polymer in an organic or non-organic solvent;
applying the composite matrix solution to at least a portion of the braided tape and the self-molding fiber cover such that the composite matrix solution permeates the braided tape and the self-molding fiber cover; and
heat-curing the composite matrix solution to thereby mechanically and chemically bond the braided tape and the self-molding fiber cover to form the composite insulation system.
2. The method of claim 1 , wherein wrapping the braided tape around the exhaust component further comprises wrapping the braided tape such that the braided tape forms an abutment with at least a portion of an adjacent braided tape wrap, wherein the braided tape and the adjacent braided tape wrap do not overlap, wherein the abutment is a tight junction.
3. The method of claim 1 , wherein method further comprises opening a planar portion of the braided tape and inserting one or more flanges of the exhaust component into the opened planar portion of the braided tape.
4. The method of claim 1 , wherein the method further comprises wrapping the braided tape around a bend in the exhaust component such that the braided tape forms an abutment with at least a portion of an adjacent braided tape wrap, wherein the braided tape and the adjacent braided tape wrap do not overlap.
5. A composite insulation system comprising:
a braided tape, the braided tape positioned on an exhaust component and conforming to the exhaust component;
a self-molding fiber cover comprising an elastic structure covering the braided tape positioned on the exhaust component and providing compression around the exhaust component; and
one or more composite matrix solutions permeating at least a portion of the braided tape and the self-molding fiber cover positioned on the exhaust component, the one or more composite matrix solutions comprising a dispersion of ground thermoplastic polymer in an organic or non-organic solvent, the one or more composite matrix solutions being heat-cured to thereby mechanically and chemically bond the braided tape and the self-molding fiber cover to form the composite insulation system.
6. The composite insulation system of claim 5 , wherein the braided tape comprises at least one of glass fibers, thermoplastic fibers, and elastic fibers.
7. The composite insulation system of claim 5 , wherein the braided tape is wrapped around the exhaust component such that the braided tape forms an abutment with at least a portion of an adjacent braided tape without overlap, wherein the abutment is a tight junction.
8. The composite insulation system of claim 5 , wherein the braided tape is wrapped around the exhaust component and secured without external clamps.
9. The composite insulation system of claim 5 , wherein a planar portion of the braided tape comprises at least one aperture structured to receive one or more flanges of the exhaust component therein.
