Abstract
Abstract A compacted assembly of folded fiberglass fabric secured in a multiple pleated truss formation sewed between flat sheets of like material for inflation forming a building of predetermined volume. The interstices in the fabric contain uniform distribution of uncured plastic resin. The assembly is covered with sheet plastic secured thereto for inflation. Following inflation of the voids within the assembly, the uncured resin is responsive to the introduction of a curing agent to all inner surfaces for curing the resin into a solid, resulting in a rigid high-strength self-supporting building or housing resistant to external stresses in any direction.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
37 words
The process recited in claim 1 wherein said fabric is relatively coarse woven from fiberglass yarn with particulate resin impregnated therein for final curing by a gas catalyst diffused into and through the interstices of said fabric.
Claim 2
Dependent Claim
62 words
The process recited in claim 1 wherein said fabric is a coarse weave of fiberglass spun rovings provided with an impregnation of uncured particulate resin and foraminated therethrough for the passage of gas to cure said resin by the diffusion of a gas catalyst in said rovings and providing for said gas to cure uncured resin in other fabric within said enclosure.
Claim 3
Dependent Claim
66 words
The process recited in claim 1 wherein the three said sheet fabric members in said truss assembly are formed from a pair of laminated fiberglass shEets with said uncured resin distributed therebetween with said laminated sheet having a plurality of spaced holes therethrough for the dispersion of a gas catalyst therein and therethrough for curing said sandwiched resin and other uncured resin in adjacent fiberglass members.
Claim 4
Dependent Claim
29 words
The process recited in claim 1 wherein each said flexible thermo-plastic sheet is made from polyethylene material of predetermined thickness and secured adjacent said apex by compatible adhesive means.
Claim 5
Dependent Claim
33 words
The process recited in claim 1 wherein each said flexible thermo-plastic sheet is made from a vinyl copolymer thermo-plastic sheet of predetermined thickness and secured adjacent said apexes by a compatible adhesive means.
Claim 6
Dependent Claim
151 words
The process recited in claim 1 used to produce an elongated inverted U shaped building having an outward curved roof portion and outward curved side portions for mounting on the surface of a substantially planar base, said truss assembly including longitudinal pleats with inner and outer angles from the apexes of the said roof and said inner and all truss members corresponding to the outward curvature of said roof and said side portions including appropriate different angles of the pleats at each opposite side portion junction with said roof portion, the entire said truss assembly covered and hermetically sealed with thermo-plastic sheet material and secured to the inner and outer apexes of all said pleats and extending over the opposite base ends of said assembly and including means for the introduction of catalyst gas within the voids within the said thermoplastic covering for curing the un-cured resin in all fiberglass members.
