本发明公开了一种碳纤维复合材料、无人机机翼及其制备方法,碳纤维复合材料包括碳纤维预浸料、碳粉末、液态环氧树脂、固化剂和表面活性剂,所述碳粉末与碳纤维预浸料的质量比为1:(50~78),所述液态环氧树脂与固化剂的质量之和与碳纤维预浸料的质量比为1:(10~22),所述表面活性剂的质量为碳纤维预浸料、碳粉末、液态环氧树脂、固化剂质量之和的1%~5%;还包括应用所述碳纤维复合材料的无人机机翼及其制备方法。本发明的制备方法具有一次成型的特点,克服了传统的碳纤维多次拼接工艺,导致接缝处容易断裂的情况,得到的碳纤维复合材料无人机机翼的表面均匀性好、表面平整度高,无明显的气泡和孔隙,整体抗冲击力较好。

    The invention discloses a carbon fiber composite material, an unmanned aerial vehicle wing and a preparation method thereof. The carbon fiber composite material is prepared from carbon fiber prepreg,carbon powder, liquid epoxy resin, a curing agent and a surfactant, the mass ratio of the carbon powder to the carbon fiber prepreg is 1: (50-78), the ratio of the mass sum of the liquid epoxy resin and the curing agent to the mass of the carbon fiber prepreg is 1: (10-22), and the mass of the surfactant is 1%-5% of the mass sum of the carbon fiber prepreg, the carbon powder, the liquid epoxy resin and the curing agent; the invention further discloses an unmanned aerial vehicle wing applying the carbon fiber composite material and a preparation method of the unmanned aerial vehicle wing. The preparation method disclosed by the invention has the characteristic of one-time molding, the situation that a joint is liable to break due to a traditional carbon fiber multi-time splicing process isovercome, and the obtained carbon fiber composite material unmanned aerial vehicle wing is good in surface uniformity, high in surface flatness, free of obvious bubbles and pores and relatively good in overall impact resistance.
