Detection of composite material, such as tensile strength, plasticity, impact toughness properties found, mechanical properties of composite substrates improve to a certain extent. By means of metallographic observation, SEM observation showed that moderate aluminum substrate with interfacial bonding strength of carbon fiber fabrics, interface interface belongs to the Exchange reaction, although the interface reactions, but not strongly, has little effect on the mechanical properties of composite materials.

SEM的应用范围

生物：种子、花粉、细菌医学：血球、病毒动物：大肠、绒毛、细胞、纤维＞材料：陶瓷、高分子粉末、环氧脂化学、物理、地质、冶金、矿物、污泥（杆菌）、机械、电机、及导电性样品如半导体（IC、线宽测量、断面、结构观察）电子材料等。

SEM的优点具有较光学显微镜好的解析度具有较大的景深，利于观察样品表面形态和尺度。能提供具实体感的立体影像。
