目前,许多导弹系统所采用的树脂多是1965年初所选择和签定的。先进的芳香/杂环聚合物(如聚酰亚胺)树脂,在60年代初、中期还处于不成熟的研究阶段,所以没有考虑它的应用。近几年来,由于芳香/杂环聚合物的重要性能和加工王艺的改进,以及聚酰亚胺的工业化生产,使这些聚合物成为许多导弹应用的重要备选材料。所选用的聚酰亚胺能够克服目前导弹部件中所采用的树脂材料所存在的某些缺点。例如,常温固化和热熔加工适用性好的聚酰亚胺可用于纤维缠绕制造坚韧的整体发动机结构壳体或防潮的衬里等。线性和交联性芳香聚酰亚胺之所以可以使用,这是由于它能显著地提高碳/碳结构件的加工重现性,并且可能比酚醛和沥青节约成本。本文将叙述和讨论一些可用的聚酰亚胺聚合物类型和技术数据,以及加工参数.
At present, many of the missile systems used are mostly selected and signed by the early 1965s. Advanced aromatic / heterocyclic polymer (such as polyimide) resin, in the early 60s, the middle is still immature research stage, so did not consider its application. In recent years these polymers have made these polymers an important candidate for many missile applications due to the important properties of aromatic / heterocyclic polymers and their improvements in processing, as well as the commercial production of polyimides. The choice of polyimide overcomes some of the shortcomings of the resin materials currently used in missile components. For example, at room temperature curing and hot melt processing good polyimide can be used for filament winding manufacturing tough overall engine structural shell or moisture-proof lining and so on. The reason why linear and cross-linkable aromatic polyimides can be used is because it significantly improves the process reproducibility of carbon / carbon structures and may save costs compared to phenolic and pitch. This article describes and discusses some of the available polyimide polymer types and technical data, as well as processing parameters.
