显微拉曼光谱被用来监测嵌入在环氧树脂基体中的碳纳米管的冷却引起的压缩变形。单壁和多壁纳米管的杨氏模量，然后可以从一个同心圆筒模型的热应力，使用D* 带位移为每个管类型。所得的弹性模量值与预测的理论值以及Treacy等人在Nature（伦敦）381，678（1996）中公布的实验数据集非常一致。
Micro-Raman spectroscopy is used to monitor the cooling-induced compressive deformation of carbon nanotubes embedded in an epoxy matrix. Young's modulus of single- and multiwall nanotubes may then be derived from a concentric cylinder model for thermal stresses, using the D*-band shift for each tube type. The resulting values of the elastic moduli are in very good agreement with predicted theoretical values, and with the published experimental data set of Treacy et at, Nature (London) 381, 678 (1996).
