Process parting design and forming method of composite material oil tank

The invention provides a process parting design and forming method of a composite material oil tank, and belongs to the technical field of composite material cabin section forming. According to the method, firstly, the oil tank is divided into a plurality of box sections through process parting, each box section is formed by paving multiple layers of fabric prepregs, curing forming and parallel production are conducted through an autoclave, the cured box sections are bonded into a whole, and curing forming is conducted through the autoclave after one-way fiber prepregs are wholly paved on the outer layer of the box sections. The oil tank formed through the method is not limited by the appearance and the size, the sealing performance and the bearing capacity are achieved, meanwhile, the production efficiency is high, and the process quality is controllable. 本发明提出了一种复合材料油箱的工艺分型设计与成型方法，属于复合材料舱段成型技术领域。本方法首先通过工艺分型将油箱分割为多个盒段，盒段由多层织物预浸料铺贴，采用热压罐固化成型，并行生产，固化后的盒段相互粘接连成整体，在其外层整铺单向纤维预浸料后热压罐固化成型。本方法成型油箱可不受外形和尺寸限制，兼具密封性和承载
