从目前玻璃钢拉挤产品的生产及应用情况看,预计美国拉挤产品的生产到1993年将达12000万磅,年均增长11%,市场销售将以每年15%的速度增长,到1993年可望达到36500万美元。拉挤生产的扩大主要取决于市场需要,目前在此方面起主要作用的仍然是热固性树脂材料。但热塑性材料也不容忽视,预计它将以年 Judging from the current production and application of FRP pultruded products, it is expected that the production of pultrusion products in the United States will reach 120 million pounds by 1993, with an average annual growth of 11%. Market sales will increase at a rate of 15% per year, and by 1993, Hope to reach 365 million US dollars. The expansion of pultruded production depends mainly on market needs, and the main role of this is still thermosetting resin materials. But thermoplastics can’t be ignored. It is expected that it will take years
