Textiles serve several important functions in cars, including upholstery, tires, composites, reinforcement of rubber parts, seat belts, and airbags. Upholstery requires abrasion and UV resistance as well as an attractive design. Tire cords and fabrics need tensile strength and adhesion to rubber to withstand fatigue. Composites must be stiff, strong, lightweight, energy absorbing, and thermally stable. Rubber reinforcement like hoses and belts require heat resistance, tensile strength, dimensional stability, and adhesion to rubber. Seat belts need tensile strength and abrasion resistance. Airbags must withstand high temperatures during inflation and remain durable when stored in a compacted state for many years.
