汽车制造业看好天然纤维增强材料（） Author: Cheng Wei With the growing awareness of environmental protection, a variety of natural fibers have been further recognized, and once again entered the field of automotive components. Due to its advantages in weight and cost, natural fiber is becoming more and more popular in automotive interior decoration and has been used in automotive exterior parts. With the growing awareness of environmental protection, a variety of natural fibers have been further recognized, and once again entered the field of automotive components. Natural fiber as insulation / sound and damping materials, especially as the polymeric material filling and reinforcing material, because in terms of weight and cost advantages and in manufacturing automotive interiors in the greater, and has begun for exterior automobile parts (such as the fender liner and a spoiler etc.) try. Performance advantages The car with natural fiber mainly refers to plant fiber, such as kenaf, hemp, flax, jute and sisal, hemp fiber and coir fiber etc.. Compared with synthetic fibers, natural fibers and their composites have the following advantages in performance. Ecological protection: properties of hemp fiber short growth period, the growth of environmental requirements is not high; the growth process without pesticide and fertilizer; growth, harvest, processing power consumption; on carbon dioxide absorption ability, can mitigate the greenhouse effect; the production process has no pollution, the use of three wastes process is free harmful chemicals (such as the recent concern formaldehyde) and particles (glass fiber components); without chemical adhesive, forming bonding process and substrate heat in one step; instead of chemical fiber and synthetic materials such as plastics, can save the limited oil resources; no toxic emissions, biodegradable landfill after incineration when using renewable cycle; Application performance: hemp fiber composite insulation, sound-absorbing performance is goo
