【摘要】 采用纤维缠绕技术成型的复合材料壳体具有耐腐蚀、高比刚度与比强度,以及优越的抗震性能等诸多优点,在航空航天、船舶运输等领域具有广阔的应用前景,但是用于成型复合材料壳体的芯模设计优劣以及脱模成败是壳体最终精度好坏的关键。论述分析了现有复合材料壳体芯模的设计特点和应用条件,对大长径比、端口小内腔大复杂壳体的芯模设计和脱模具有重要的指导意义。更多还原

【Abstract】 Composite shell molded by filament winding technology has many advantages such as corrosion resistance,high specific stiffness and strength,excellent seismic performance,which has broad prospects in the aerospace,marine transportation applications.However,the manufacturing and demolding of core mold for forming a composite shell are the key and challenges to its ultimate precision.In this paper,we discusses and analyses features and applications of existing core molds such as metal core mold,plaster core mold,water-soluble core mold,rubber core mold.The paper has important guiding meaning in core mold design and demolding of high aspect ratio,small point large cavity complex shell.更多还原
