- 3. The fibrous web of claim 1, said compound modulus comprising a first modulus low load elongation of greater than 10% @ the greater of 5 pli or 25% of the fibrous web stress limit, and a second modulus fibrous web stress limit of at least 15 pli.
- 4. The fibrous web of claim 1, said first yarn type comprising greater than 10% by weight of yarn used in selected said direction.
- 5. The fibrous web of claim 1, said second yarn type comprising fibers from among the group of fibers consisting of para-aramid, liquid crystal polymer, and UMW polyethylene.
- 6. A woven fabric with a compound modulus in the CM direction comprising one yarn type in the MD direction and at least two yarn types in the CM direction, the second yarn type of said two yarn types having a higher fiber modulus and greater fiber shrinkage crimp than the first yarn type of said two yarn types, said compound moduli comprising a first modulus low load elongation of greater than 5% @ 5 pli, and a second modulus fabric stress limit of at least 15 pli.
- 7. A fiber reinforced elastomeric material comprising a fibrous web with a compound fabric modulus in at least one of warp and fill directions, said fibrous web comprising at least a first yarn type and a second yarn type woven together in a common direction, said second yarn type having a higher fiber modulus and greater shrinkage crimp than said first yarn type.
- 8. The fiber reinforced elastomeric material of claim 7, said compound modulus comprising a first modulus low load elongation of greater than 5% @ 5 pli, and a second modulus fabric stress limit of at least 15 pli.
- 9. The fiber reinforced elastomeric material of claim 7, said second yarn type comprising fibers from among the group of fibers consisting of para-aramid, liquid crystal polymer, and UMW polyethylene.
- 10. A method for making a woven fabric with a compound modulus in at least one of warp and weft directions comprising the steps of:weaving a fibrous web with at least two yarn types in at least one of said warp and weft directions, said two yarn types having different fiber shrinkage characteristics and different fiber moduli, and processing said fibrous web for fiber shrinkage.
- 11. The method of claim 10, said fiber shrinkage characteristics being thermal, the second yarn type of said two yarn types having a higher said fiber modulus and lower said thermal shrinkage characteristic than the first yarn type of said two yarn types, said step of processing comprising thermal processing at a temperature greater than 100 F.
- 12. The method of claim 10, said at least one of warp and weft directions comprising both warp and waft directions.
- 13. The method of claim 11, said second yarn type having a fiber modulus of at least 100 pli and a thermal fiber shrinkage characteristic of less than 5%, said first yarn type having a fiber modulus low load elongation of greater than 5% @ 5 pli and a thermal fiber shrinkage characteristic of greater than 15%.
- 14. The method of claim 13, said compound modulus of said fibrous web after said step of thermal processing comprising a first modulus low load elongation of at least 5% @ 5 pli, and a second modulus fabric stress limit of at least 15 pli.
- 15. The method of claim 14, said yarn type comprising at least one from the group consisting of filament, spun, and intimate blend yarns.
- 16. The method of claim 15, said step of weaving comprising weaving a construction from the group of weave constructions consisting of plain, basket, and pattern weaves.
