本发明涉及波纹碳纤维预制体的制备方法和包含该波纹碳纤维预制体的碳-碳复合材料。在一个实例中,所述方法包括在液体载体中混合多个碳纤维以形成混合物,使该碳纤维混合物沉积成层,在该碳纤维层中形成多个波纹,和使该波纹碳纤维层硬化以形成波纹碳纤维预制体。在另一个实例中,所述方法包括使第一波纹碳纤维预制 The present invention relates to a process for producing a corrugated carbon fiber preform and a carbon-carbon composite material containing the corrugated carbon fiber preform. In one example, the method includes mixing a plurality of carbon fibers in a liquid carrier to form a mixture, depositing the carbon fiber mixture into a layer, forming a plurality of corrugations in the carbon fiber layer, and hardening the corrugated carbon fiber layers to form corrugated carbon fibers Preform. In another example, the method includes prefabricating the first corrugated carbon fiber
