Manufacturing method of polyimide composite

A manufacturing method of a polyimide composite includes mixing a polyamic acid solution and a fiber cloth, and baking it to form a prepreg. Next, stacking multiple the prepregs to form a prepreg stack. Next, performing a first hot pressing, which the prepreg stack is pressed by a first stress at a...

Zusammenfassung:	A manufacturing method of a polyimide composite includes mixing a polyamic acid solution and a fiber cloth, and baking it to form a prepreg. Next, stacking multiple the prepregs to form a prepreg stack. Next, performing a first hot pressing, which the prepreg stack is pressed by a first stress at a first heating temperature. Next, performing a second hot pressing, which the prepreg stack hot pressed by the first hot pressing is pressed by a second stress at a second heating temperature to form the polyimide composite. The second heating temperature is higher than the first heating temperature, and the second stress is higher than the first stress.
