Carbon fiber composite autoclave molding method for rail control console
By using an elastic pressure compensation pad and independent temperature-controlled thermocouples for monitoring during autoclave molding, combined with a resin curing kinetic model, the uniformity of the temperature field in the thickness abrupt change region and the precise matching of pressurization timing were achieved. This solved the problem of asynchrony between the resin viscous flow state and the gel point, and improved the molding quality of the track control console.

Abstract
本发明属于复合材料热压罐成型技术领域，涉及轨道司控台碳纤维复合材料热压罐成型方法。本发明通过在厚度突变区设弹性压力补偿垫，埋入热电偶，在升温阶段基于最大温度偏差对负偏差区域进行局部热补偿并降升温速率至收敛；基于树脂固化动力学模型计算实时黏度曲线，于黏度局部极小值且偏差收敛时加压操作；保温降温阶段以最小化温度场均匀度偏差为目标动态调节各独立温控回路介质流量；脱模操作以整体温度变化率趋近零且最高温度低于实时玻璃化转变温度为条件。本发明解决了因厚度突变导致的温度场不均、树脂固化不同步及加压失配问题，从而达到了消除温度差异、抑制构件翘曲变形、减少孔隙与分层缺陷、提升成型精度的效果。
