大尺寸多格栅复合材料框架共固化成型工艺

从铺层工艺优化设计、产品成型压力的保证等方面阐述大尺寸多格栅复合材料框架热压罐整体

成型的工艺方法。工程实践证明,将整体结构分解成多个工艺单元,先完成单元铺层,合模后完成剩余铺层的

方法可以完成该框架的坯件预成型;软硬模交替使用,软模传压、硬模保证框架几何尺寸的工艺方法能够实现

该框架的整体固化成型。制成的产品不仅上、下面平面度等形、位公差满足设计要求,产品的薄厚偏差、胶的含

量和产品质量偏差均能控制在允许的范围内。

Co-Curing Molding Technique of Large Size Multi LatticeStructured Composite Framework

This article elaborates on the integral forming in the autoclave of large size multi lattice structured composite

with particular emphasis on the optimistic design of overlay processing and assurance of forming pressure. It is

proved by engineering practice that the ware preforming of such frame can be realized by breaking down the overall

structure into multi technique units, in which unit overlay is first completed, followed by rest of overlay after matching

molds; and the technique of alternative use of soft and hard abrasives, pressure transmitting of soft abrasives, assurance

of frame geometrical size by hard abrasives, can achieve the integral co-curing molding. The products manufactured can

meet the designing requirements of deviation of shape and position in terms of flatness of upper and lower surface, and

its deviation of thickness, content of rubber and product quality can be also controlled within an allowable range.
