现有的碳纤维布与树脂复合时会产生气泡和包气，影响所得碳纤维复合材料的美观性及使用寿命。
发明内容
本发明所要解决的技术问题是：本发明的目的在于提供一种糊剂有效包覆碳纤维布，不会产生气泡，性能好的碳纤维复合材料的制备方法。

(2)将碳纤维布的两个侧面分别涂覆第一层糊剂，烘干固化，再涂覆第二层糊剂，烘干塑化，压花，冷却，切边，收卷得碳纤维复合材料。
本发明的有益效果在于：本发明的碳纤维复合材料的制备方法，使用抽真空条件下搅拌糊剂原料，解决了碳纤维布复合涂布时会产生气泡和包气，导致透明度不够且影响性能的技术问题；且采用两道工艺涂层上糊，避免碳纤维易变形且脆，纤维易折断的问题。由本发明方法制备的碳纤维复合材料制备的产品较薄，气密性好，拉力性能及抗撕裂性能良好。
