High-Strength Materials for Tire Manufacturing

Composite material with enhanced integration between a high modulus fabric and thermoplastic elastomer. The composite has a woven fabric made of high modulus fibers sandwiched between thermoplastic elastomer layers. The thermoplastic elastomer penetrates the fabric openings and exposes at the other side. This anchors the fabric and thermoplastic. The fabric can have multifilament or monofilament yarns, but with specific weave characteristics. The thermoplastic elastomer softens and pushes through the fabric openings. The exposed area rate of the thermoplastic on the opposite side is 10% or more. This allows the thermoplastic to anchor the fabric and enhance integration.

Preparing composites from solid elastomers and wet fillers with improved filler dispersion and rubber composite properties. The method involves charging a mixer with solid elastomer and wet filler (filler in liquid form), mixing at elevated temperatures to evaporate the liquid and discharging the composite with dispersed filler at high loading. The elevated mixing temperatures and liquid removal aid filler dispersion. The composite has reduced liquid content compared to wet mixing. This provides better filler dispersion in solid elastomer compared to traditional wet mixing.

Method to prepare composites from solid elastomer and wet filler that provides high filler dispersion quality and functionality in the composite and vulcanized rubber. The method involves charging a mixer with solid elastomer and wet filler (liquid filler), mixing at elevated temperatures to evaporate some of the liquid, and discharging the composite with filler dispersed in the elastomer.
