The invention discloses a carbon fiber preform and a preparation process thereof, a brake disc and a vehicle, and the preparation process of the carbon fiber preform comprises the following steps: 1) carbon fiber traction: a plurality of carbon fiber filaments are pulled in parallel through a traction device, so that the pulled ends of the carbon fiber filaments are all located in a first arc; 2) cutting: cutting one end, deviating from the traction device, of the carbon fiber yarn through a cutting device, and enabling the cut end of the carbon fiber yarn to be located in the first arc to form a carbon fiber layer; (3) repeating the steps (1) and (2); 4) stacking: stacking a plurality of carbon fiber layers; and 5) needling: needling the plurality of stacked carbon fiber layers by using a needling machine to obtain the carbon fiber preform. According to the preparation process of the carbon fiber preform, generation of cutting waste is reduced, and the utilization rate of the carbon fibers is increased.
本申请公开了一种碳纤维预制体及其制备工艺、刹车盘和交通工具,所述碳纤维预制体的制备工艺包括步骤:1)、碳纤维牵引:通过牵引装置并列牵引若干碳纤维丝,使得碳纤维丝被牵引的一端均处于第一圆弧内;2)、切割:通过切割装置切断碳纤维丝背离牵引装置的一端,且碳纤维丝被切断的一端均处于第一圆弧内,形成碳纤维层;3)、重复步骤1)和2);4)、层叠:将若干碳纤维层层叠;5)、针刺:利用针刺机对层叠的若干碳纤维层进行针刺,并得到所述碳纤维预制体。本发明所述碳纤维预制体的制备工艺,减少切割废料的产生,提高碳纤维的利用率。
