洛克希德导弹空间公司计划采用杜邦公司的低密度、高强度、高模量PRD——49——Ⅲ纤维,研制一种三叉戟Ⅰ(C_4)导弹第三级所需的高性能纤维缠绕燃烧室,计划分三步进行:(1)确定材料的基本性能的特性数据;(2)用小尺寸的燃烧室试验来评定设计和制造设想;(3)用全尺寸壳体的爆破和结构试验来验证和确定设计与制造技术。本文提供了材料的基本性能以及小尺寸和全尺寸壳体的数据,数据证实了PRD—49—Ⅲ纤维燃烧室要比S—901玻璃纤维燃烧室轻35%,且复合材料的环向模量增加70%。
Lockheed Martin Missile Space Company plans to use DuPont ’s low density, high strength, high modulus PRD - 49 - Ⅲ fiber to develop a Trident I (C_4) missile third stage high performance filament wound combustion Room, the plan is divided into three steps: (1) to determine the basic properties of the material properties of the data; (2) small-scale combustion chamber test to assess the design and manufacturing ideas; (3) full-size shell blasting and structural testing To verify and identify design and manufacturing techniques. This document provides basic material properties as well as data for small and full-size housings. The data confirm that the PRD-49-III fiber combustor is 35% lighter than the S-901 fiberglass combustor and the composite’s hoop modulus Increase by 70%.
