摘要
从二氧化碳排放量的角度,分析了以玻璃纤维增强热塑性塑料为材质的车体,旨在大量减少二氧化碳的排放量。汽车车体的重量大大减轻,从而节约了30%的燃油消耗。实验室采用玻璃纤维增强的聚丙烯为材质,并且以应力应变的时间关系为模型,制造出用来生产尺寸合适的车体的混合物。实验室采用单螺旋杆挤压机来制备测试品,并采用数学模型来确定增强测试品的应力应变关系。在混合物中加入30%的玻璃纤维,可以按照规定的应力大小来生产汽车车体。
Body cars produced from fibber-glass reinforced thermoplastics is investigated in this paper from carbon dioxide emissions point of view. The objective is to reach major reductions in the amount of carbon dioxide emitted. This was achieved due to the considerable weight re-duction of the automobile body reaching to 30% saving in fuel consumption. Polypropylene reinforced with fibber-glass is prepared in our lab-oratory. The stress strain time correlation is modelled in order to produce the blend appropriate for the production of body cars with acceptable specifications. A single screw extruder is used to prepare the required samples. Mathematical models are used to evaluate stress strain correla-tions of the reinforced samples. Additions of 30% fibber-glass to the blend lead to produce cars with the required stress specifications.
