The interface adhesive properties and mechanical properties of shape memory alloy composites were experimentally investigated. The two diameters of shape memory alloy (SMA) wire were surface modified by sandpaper, acid corrosion and alkali corrosion. Pull-out tests of single fiber and tensile tests of composite laminates were carried out. The results show that SMA after acid corrosion is the most effective to improve interface adhesive properties. With the increase of SMA diameter, the contact area between the matrix and SMA increases, so the degree of interfacial bonding is more obvious. The mechanical properties of SMA-modified composite laminates polished by sandpaper have been fully improved. SMA plays a full role in tensile resistance as long as the interface adhesive strength is large enough. Scanning electron microscopy shows that the surface roughness of the SMA wire treated in H₂SO₄ is more obvious than the other two.

实验研究了形状记忆合金复合材料的界面粘合性能和力学性能。两种直径的形状记忆合金（SMA）线材通过砂纸、酸腐蚀和碱腐蚀进行表面改性。进行了单纤维的拉拔试验和复合层压板的拉伸试验。结果表明，酸腐蚀后的SMA对提高界面粘合性能最有效。随着SMA直径的增大，基体与SMA的接触面积增大，界面结合程度更加明显。砂纸打磨后的SMA改性复合层压板的力学性能得到了充分的提高。只要界面粘合强度足够大，SMA就可以充分发挥抗拉强度的作用。₂ SO ₄比其他两个更明显。
