The testing process of carbon fiber multifilament is studies and analyzed.The tension,impregnation time,resin ratio,curing temperature,and resin content duting the testing process were investigated.It is found that,without damage to the fiber,higher tension should be applied during the sample preparation to maximize the strength of carbon fiber.The impregnation time should not be too short,to avoid the incomplete impregnation.The resin ratio should be appropriate to facilitate curing while considering the long-term operation of the equipment,strengthen the process.
