Does carbon fiber need to be vacuum pressed?
碳纤维是否需要真空压制？
Sometimes, as a prepreg or in a bagging application, carbon fiber needs to be vacuum pressed. Vacuum pressing optimizes the fiber-resin ratio in the composite piece. And prevents air from getting trapped in layers. It also stops shifting during the orientation of the fiber.
作为预浸料或在袋装应用中，有时需要对碳纤维进行真空压缩。真空压制可优化复合件中的纤维和树脂的比率， 并防止空气滞留。此外，它还会在纤维取向期间停止移动。
