RIGID WATER TIGHT REPAIR WRAP
A repair wrap for repairing or strengthening an inanimate object. The repair wrap includes a fabric, where the fabric includes one or more fibers. The repair wrap also includes a hardening material. The fabric is configured to be wrapped around a portion of an inanimate object. Curing the hardening material is configured to form a shell about the portion of the inanimate object.
1 . A repair system, the repair system comprising:
an inanimate object having first and second portions and a broken portion positioned between the first and second portions;
a fabric, wherein the fabric includes one or more fibers; and
a hardening material, wherein the hardening material:
is pre-impregnated in the fabric in an inactivated state; and
the amount of pre-impregnated hardening material is sufficient to completely saturate the fabric;
wherein the pre-impregnated fabric is wrapped around the first and second portions of the inanimate object in direct contact with the inanimate object; and
wherein curing the hardening material forms a shell about the first and second portions of the inanimate object, wherein the shell:
has high impact strength; and
is water tight.
2 . The repair system of claim 1 , wherein completely saturating the fabric includes:
adding sufficient hardening material to eliminate portions of the fabric without hardening material; and
refraining from adding an amount of hardening material that will create one or more channels through the hardening material during curing.
3 . The repair system of claim 1 , wherein no channels exist that extend through the cured hardening material.
4 . The repair system of claim 1 , wherein the hardening material includes:
a resin.
5 . The repair system of claim 4 , wherein the resin includes:
a two part epoxy.
6 . The repair system of claim 4 , wherein the resin includes:
methylene diphenyl diisocyanate.
7 . The repair system of claim 1 , wherein the one or more fibers include:
fiberglass.
8 . The repair system of claim 1 , wherein the one or more fibers include:
carbon fiber.
9 . The repair system of claim 1 , wherein the one or more fibers include at least one of:
aramid fibers; or
para-aramid fibers.
10 . The repair system of claim 1 , wherein the one or more fibers include:
basalt fibers.
11 . The repair system of claim 1 , wherein the one or more fibers include at least one of:
polyester; or
nylon.
12 . The repair system of claim 1 , wherein the one or more fibers include:
natural fibers.
13 . The repair system of claim 1 , wherein the thickness of the fabric is such that it has a weight of between 180 grams per square meter and 450 grams per square meter.
14 . The repair system of claim 1 , wherein the one or more fibers are woven to form the fabric.
15 . The repair system of claim 1 , wherein the one or more fibers are knit to form the fabric.
16 . A repair system, the repair system comprising:
an inanimate object including first and second portions and a broken portion positioned between the first and second portion;
a fabric, wherein the fabric includes:
one or more fibers; and
the one or more fibers are knit to form the fabric; and
a resin disposed in the fabric, wherein:
the resin is pre-impregnated in the fabric in an inactivated state; and
the amount of pre-impregnated resin is the amount that just barely but completely saturates the cloth;
the resin is water activated; and
the resin is configured to cure in exposure to air;
wherein the fabric is wrapped around the first and second portions of the inanimate object and in direct contact with the inanimate object;
wherein curing the resin forms a shell about the first and second portions of the inanimate object, wherein:
the shell has high impact strength; and
the shell is water tight;
no channels exist that extend through the cured hardening material; and
wherein a ratio of resin to fabric by weight is 0.29:1 to 0.44:1.
17 . The repair system of claim 16 , wherein the resin includes an additive disposed in the resin.
18 . The repair system of claim 17 , wherein the additive includes at least one of:
rubber;
sand;
wood particles; or
sawdust.
19 . The repair system of claim 16 , wherein the inanimate object comprises at least one of:
wood;
metal;
glass;
plastic;
rubber;
composites;
fiberglass;
ceramic; or
concrete.
20 . The repair system of claim 16 , wherein the ratio of resin to fabric by weight is approximately 0.365:1.
