AI Technical Summary
Technical Problem
In existing autoclave processes, carbon fiber composite prepregs suffer from problems such as uneven resin and fiber distribution, numerous pores, insufficient interlayer bonding, and many surface defects, leading to unstable composite material performance.
Method used
An ultrasonic-assisted autoclave device is used to apply ultrasonic vibration during the prepreg layering process, combined with heated roller pressing, to achieve uniform resin distribution in the fiber gaps, reduce interlayer and intralayer porosity, and improve the bonding strength between fibers and resin.
Benefits of technology
This method achieves uniform prepreg layering, reduces porosity, and improves interlayer bonding strength and the forming quality of composite materials.

Abstract
本发明涉及碳纤维复合材料热压成型领域，具体涉及一种超声波辅助热压罐制备碳纤维预浸料铺层方法和装置。为解决热压罐工艺的预浸料铺层质量差等问题，该装置利用超声波振动改变熔融状态下树脂的粘度和流动性，再通过加热辊辊压促进预浸料层间树脂和纤维的均匀结合。该装置包括工作平台两侧丝杠导轨连接辊压模块，丝杠螺母上螺栓连接升降模块和超声波模块，升降模块转动连接电磁加热的加热辊。升降模块调节预浸料铺层过程中超声波距离和辊压压力，超声波装置的均匀排布促进整个预浸料平面纤维间隙熔融树脂均匀分布，辊压模块减少层间及层内的孔隙和碳纤维预浸料表面缺陷，这一方法和装置为下一步的热压罐固化成型提供了成型质量更好的预成型件。
