Full definition
Woven or knitted fabric layers embedded within an elastomer matrix to increase tensile strength, reduce elongation, improve dimensional stability, and enhance tear and puncture resistance. Common reinforcement fabrics: nylon (PA6, PA66 — high strength and flexibility), polyester (PET — low elongation, good dimensional stability), aramid/Kevlar (highest strength-to-weight, minimal elongation), cotton (good rubber adhesion, limited use in modern products), and fiberglass (for timing belt cords). Fabric construction: plain weave (balanced properties), twill (better drape and flexibility), or bias-cut (45° orientation for conformability). In neoprene and rubber sheets: 1-ply or 2-ply reinforcement transforms a stretchable sheet into a dimensionally stable diaphragm or gasket material with 2-5x higher tensile strength. In conveyor belts: EP (polyester-nylon) fabric plies form the carcass carrying all belt tension. Adhesion between textile and rubber: achieved through RFL (resorcinol-formaldehyde-latex) dip treatment of the fabric. Per ISO 14890 for conveyor belt reinforcement specification.
