Abstract
A flexible composite expansion joint material comprises a fluoropolymer containing woven fabric substrate with mutually perpendicular warp and fill yarns. The substrate is subdivided into plural segments which are arranged successively in a longitudinally extending assembly with the warp and fill yarns of each segment extending obliquely with respect to the assembly length. At least one other component extends over the assembly length. The successively arranged substrate segments are spliced together and integrally joined to the other component by lamination under conditions of elevated temperature and pressure.

A flexible composite expansion joint material comprising:
- plural segments of a fluoropolymer containing woven fabric substrate, said substrate having mutually perpendicular warp and fill yarns, said segments being arranged successively in a longitudinally extending assembly with said warp and fill yarns extending obliquely with respect to the length of said assembly;
- and
- at least one other component extending over the length of said assembly, successive segments of said assembly being spliced together and integrally joined to said other component by lamination under conditions of elevated temperature and pressure.
A method of fabricating a flexible laminated composite expansion joint material comprising:
- a) providing a length of a fluoropolymer containing woven fabric, said fabric having mutually perpendicular warp and fill yarns;
- b) longitudinally subdividing said fabric into plural segments;
- c) arranging said segments successively in a longitudinally extending assembly with said warp and fill yarns extending obliquely with respect to the length of said assembly;
- d) overspreading the length of said assembly with at least one other component;
- e) splicing the successive sections of said assembly together;
- and
- f) integrally joining the thus spliced sections to said other component.
