自从20世纪40年代复合材料商业化以来,美国复合材料业持续在发展、多种经营和技术竞争方面取得了显著的成绩。自1960年以来,当复合材料业开始统计市场交易数据的时候,复合材料业的平均增长率已达到6.5%,大约是同期美国经济增长率的2倍(见图1)。把复合材料业的增长率作为同期其它行业的相应基准的话,其增长率是美国钢铁消耗增长率的2倍,GDP增长率的3倍,铝消费增长率的4倍,复合材料销售量增长的15倍。尽管复合材料业已趋于成熟增长平缓,但我们还是预计复合材料业将成为持续增长的行业。材料的替代已成为复合材料业发展的动力。复合材料或增强塑料替代其它传
Since the commercialization of composite materials in the 1940s, the composite materials industry in the United States has made remarkable achievements in its development, diversification and technological competition. Since 1960, when the composites industry started to count market transactions, the average growth rate for the composites industry reached 6.5%, about double the U.S. economic growth over the same period (Figure 1). Taking the growth rate of the composites industry as the corresponding benchmark for other industries in the same period, the growth rate is twice that of the U.S. steel consumption growth rate, 3 times the GDP growth rate, 4 times the aluminum consumption growth rate, and the composite material sales growth rate 15 times. Although the composites industry has matured steadily, we expect the composites industry to continue to grow. Substitution of materials has become the driving force behind the development of the composites industry. Composite or reinforced plastic to replace other pass
