Abstract
An improved fabric backing for the manufacture of glass-reinforced thermoplastic panels that exhibits significantly greater foam adhesion than its scrim counterpart. That fabric backing includes a plurality of looped section extending upwardly (and inwardly) from its base for enhancing adhesion thereto. The combination is subjected to lamination for making an improved glass-reinforced thermoplastic interior wall panel. That wall panel can be used in a storage unit, such as a refrigerated trailer, railcar, shipping container and/or box truck.
Claims20
An improved fabric using loops for connecting to a back side of a wall during manufacture of a glass-reinforced thermoplastic wall panel, said loop fabric comprising:
- a plurality of fully looped sections adhered at both loop ends into a polymer woven wall substrate, said looped sections adapted for extending outwardly above the polymer woven wall substrate prior to having a thermoplastic resin injected thereabout to form an improved, laminated wall panel therefrom.
A composite sheet comprised of:
- a) a base layer of reinforcing woven or non-woven fibers for impregnating with a thermoplastic resin, said base layer having a substrate into which a plurality of fully looped sections are interwoven for extending about 0.5 to 6 mm outwardly beyond the substrate;
- and
- b) a thermoplastic resin injected about the base layer to create an improved mechanical bond between the injected thermoplastic resin and the base layer.
An improved storage unit made from a plurality of glass-reinforced interior wall panels, said interior wall panels being made from a thermoplastic foam adhered to a wall backing having a substrate which includes a plurality of fully looped sections which extend outwardly beyond the wall backing for greater adhesion of the thermoplastic foam thereto.
