摘要:
A pneumatic tire comprises a carcass (12), a tread (19) disposed radially outward of the carcass (12) and a crown reinforcing structure (14) interposed between the tread (19) and the carcass (12) in circumferential relation to the carcass (12). The crown reinforcing structure (14) includes a belt assembly having at least one belt ply (15, 16) with reinforcement cords extending parallel to one another and an overlay structure (18) including an aliphatic polyamide reinforced layer. The aliphatic polyamide reinforced layer makes an angle of between -5 degrees and +5 degrees with an equatorial plane (EP) of the tire (10), the aliphatic polyamide reinforced layer including aliphatic polyamide cords having a 1900/1 to 3000/1 Dtex, 1 to 10 turns per 2.54 cm cord construction.
摘要:
The present invention is directed to a pneumatic tire comprising at least one component, the at least one component comprising a rubber composition, the rubber composition comprising a diene based elastomer and from 1 to 100 parts by weight, per 100 parts by weight of elastomer, of a polybenzobisoxazole (PBO) short fiber having a length ranging from 0.5 to 20 mm and a thickness ranging from 1 to 80 microns, and from 1 to 30 parts by weight, per 100 parts by weight of elastomer, of an epoxidized palm oil.
摘要:
A pneumatic tire comprising at least one component selected from the group consisting of apex(16), flipper (24) and chipper (26), the at least one component comprising a rubber composition, the rubber composition comprising a diene based elastomer and from 1 to 50 parts by weight, per 100 parts by weight of elastomer (phr), of a polybenzobisoxazole (PBO) fiber having a length ranging from 0.5 to 20 mm having a thickness ranging from 10 to 30 microns, and from 1 to 50 phr of an epoxidized polyisoprene having a number-average molecular weight of in a range of from 5000 to 100000.
摘要:
The invention relates to the treatment of yarns for use in reinforcement of rubber products. Such treatment comprises application to the yarn of an aqueous emulsion of polyester and/or epoxy adhesive, or an aqueous alkaline dispersion of rubber latex and resorcinol-formaldehyde resin adhesive, wherein said adhesive contains a minor amount of particulate, water insoluble starch composite of starch and water insoluble plasticizer therefor. Such yarns may be in a form of a cord comprised of a plurality of yarns. The invention further relates to such treated yarns. The invention additionally relates to such treated yarns and a composite of rubber and said treated yarns. The invention additionally relates to an article of manufacture such, as for example, a rubber tire, having at least one component comprised of said composite.
