碳纤维复合材料具有比强度高,模量高,轴向热膨胀系数小等优点,在国际上越来越多的应用在航空工业。我国也开始进行试验性应用。在接触腐蚀试验中需采用碳纤维复合材料试件,该材料是含648酚醛环氧树脂30％的碳纤维米字型铺层多向板。此种材料的切割与钻孔,据资料介绍容易 Carbon fiber composite material has the advantages of high specific strength, high modulus and small axial thermal expansion coefficient, and is increasingly used in the aviation industry in the world. My country has also started experimental applications. In the contact corrosion test need to use carbon fiber composite material specimens, the material is containing 30% of the 648 phenolic epoxy resin m-shaped plywood multi-directional board. This material cutting and drilling, according to the information introduced easily
