Компания SGMW начала массовое производство автомобильных интерьеров из бамбуковых композитов

SGMW Industrializes Bamboo Fiber Composites for its Automotive Interiors SGMW is replacing conventional plastics with locally sourced and manufactured high-performance bamboo fiber composites across 11 part categories in 20+ vehicle models. Automotive company SAIC‑GM‑Wuling (SGMW, Liuzhou, China) has introduced bamboo fiber‑reinforced composites into interior trim components across more than 20 of its production vehicle models, covering 11 part categories including headliners, seatback panels, trunk trim, sun visors and central floor carpets. The initiative was a collaborative effort with the International Centre for Bamboo and Rattan (ICBR) and other partners. The program addressed three core technical areas: lightweight bamboo fiber manufacturing, fiber‑resin interface bonding and air‑flow/mechanical uniform fiber mat forming. SGMW has established a full industrial chain integrating bamboo growers, fiber processing bases, parts suppliers and vehicle assembly, and has achieved volume production of high‑performance bamboo fiber composite materials. The bamboo fiber composite is manufactured from locally sourced bamboo in Guangxi. An interfacial toughening approach using low‑melting point polymers improves fiber‑matrix adhesion, with stepped pressure profiles during molding reducing void content. An air‑flow and mechanical spreading technique enables uniform mat forming for continuous production. The finished panels contain 75% or more bamboo fiber by weight, with density ≤0.5 gram/cubic centimeter — significantly lower than conventional engineering plastics, SGMW reports — and a flexural modulus of 257.3 megapascals, meeting automotive interior requirements. A deep‑draw compression process enables forming depths exceeding 25 centimeters, addressing the limited flowability of natural fibers in complex 3D geometries. The material also exhibits near‑zero formaldehyde emissions, reduces carbon emissions by approximately 0.55 kilogram per kilogram of material compared with conventional plastics and degrades more than 90% within 360 days under natural conditions. SGMW operates one bamboo fiber line and two composite panel lines in Guangxi, with combined annual capacity of 200,000 square meters of finished panels and more than 4,000 tons of fiber raw material. Bamboo interior parts are currently in production on SGMW high‑volume models including Hongguang MINIEV, Binguo, Xingguang, Yunhai and Huajing S, with plans to extend to the full vehicle lineup from 2026.
