Wood-plastic composite (WPC) is a very promising and sustainable green material to achieve durability without using toxic chemicals. The term WPCs refers to any composites that contain plant fiber and thermosets or thermoplastics. In comparison to other fibrous materials, plant fibers are in general suitable to reinforce plastics due to relative high strength and stiffness, low cost, low density, low CO2 emission, biodegradability and annually renewable. Plant fibers as fillers and reinforcements for polymers are currently the fastest-growing type of polymer additives. Since automakers are aiming to make every part either recyclable or biodegradable, there still seems to be some scope for green-composites based on biodegradable polymers and plant fibers. From a technical point of view, these bio-based composites will enhance mechanical strength and acoustic performance, reduce material weight and fuel consumption, lower production cost, improve passenger safety and shatterproof performance under extreme temperature changes, and improve biodegradability for the auto interior parts.
木塑复合材料（WPC）是一种非常有前景的可持续绿色材料，无需使用有毒化学物质即可实现耐久性。术语WPC是指任何含有植物纤维和热固性或热塑性塑料的复合材料。与其他纤维材料相比，由于植物纤维具有相对较高的强度和刚度、低成本、低密度、低二氧化碳排放、生物降解性和每年可再生性，通常适合增强塑料。植物纤维作为聚合物的填料和增强剂，目前是增长最快的聚合物添加剂类型。由于汽车制造商的目标是使每个部件都可回收或可生物降解，基于可生物降解聚合物和植物纤维的绿色复合材料似乎仍有一定的发展空间。从技术角度来看，这些生物基复合材料将提高机械强度和声学性能，减轻材料重量和燃料消耗，降低生产成本，提高乘客安全性以及在极端温度变化下的抗碎性能，并提高汽车内饰部件的生物降解性。
