Honda has developed a new “bio-fabric” that uses PPT (polypropylene terephthalate) as its base material. This plant-based fabric—the PPT is produced through the polymerization of propanediol, which is made from corn—is claimed to be both durable and resistant to sunlight, which means it is suitable for use in vehicle interiors. The expected uses are seat covers, door panels, headliners, and floor mats. Honda’s next fuel-cell vehicle—expected within the next three years—will be the first to use the bio-fabric. Honda hopes to expand its use into regular production from 2009, a timetable helped by the fact that the bio-fabric does not require any changes in the fabric production process. Honda estimates the use of this material will reduce energy used during the production process by 10% to 15%.
