    • An intelligent control system for directing a process for curing parts made of fiber-reinforced composite material in an autoclave. The system uses data gathered during the curing processing to calculate repetitively the temperature of the autoclave required to establish and maintain a predetermined cure temperature. The system accounts for heat generated by the exothermal reaction of the resin during polymerization. The control recalculates an optimal autoclave temperature at periodic intervals during the cure cycle on the basis of temperature data from the part being cured and temperature within the autoclave. The optimal autoclave temperature is determined from calculated values representing resin heat, maximum offset, lag time and degree of cure of the resin. Control signals produced by a computer that executes control algorithms stored in electronic memory accessible to the processor cause corresponding changes in the temperature of the autoclave needed to cure the part without overheating and in less time than with a conventional autoclave temperature control.
    • 一种智能控制系统,用于引导在高压釜中固化由纤维增强复合材料制成的部件的工艺。 该系统使用在固化处理期间收集的数据来重复地计算建立并保持预定固化温度所需的高压釜的温度。 该系统考虑到聚合期间树脂的放热反应产生的热量。 基于来自固化部分的温度数据和高压釜内的温度,该控制在固化循环期间以周期性间隔重新计算最佳高压釜温度。 最佳的高压釜温度由表示树脂热量,最大偏移,滞后时间和树脂固化程度的计算值确定。 由执行存储在处理器可访问的电子存储器中的控制算法的计算机产生的控制信号导致固化部件所需的高压釜温度的相应变化而不会过热,并且在比常规的高压釜温度控制下更短的时间内。
