德国航空航天旅游研究所已评价了用各种天然纤维和天然热塑性聚合物(如淀粉或纤维素衍生物)生产增强复合材料的可能性,以开发能中和CO_2且能生物降解的复合材料,因它比玻璃纤维轻、便宜、粘合性更好,而且力学性能相似,并对外界环境有限定的稳定性,特别适合制作汽车及火车车箱内衬板等户外用品。目前Mercedes(梅塞代斯)E级小汽车内衬板已用亚麻—剑麻增强环氧树脂复合材料制作。 因纤维增强复合材料重量轻、有粘弹性并有胜过传统金属材料的力学性能,已被喷气飞机等高技术领域广泛采用。如喷气飞机壳体重50％,燃料重25％,有效负载仅25％;若使壳体减重10％,会使有效负载增加20％,能极大增加航空航天器的功能。若用高性能复合材料使
The German Institute of Aeronautics and Astronautics Tourism has evaluated the possibility of using various natural fibers and natural thermoplastic polymers such as starch or cellulose derivatives to produce reinforced composites to develop composites that are capable of neutralizing CO 2 and biodegradable, Because it is lighter than glass fiber, the adhesive is better, and mechanical properties are similar, and the stability of the external environment is limited, especially for the production of cars and train cars linings and other outdoor products. Currently, the Mercedes Class-E car liner has been made of linen-sisal reinforced epoxy composites. Due to the fiber-reinforced composite material is light weight, viscoelastic and has better mechanical properties than traditional metal materials, it has been widely adopted by high-tech fields such as jet aircraft. Such as jet aircraft shell weight 50%, fuel 25% weight, payload only 25%; if the shell weight loss 10%, the payload will increase by 20%, can greatly increase the function of the spacecraft. If using high-performance composite materials
