用相移阴影莫尔法（PSSM）测量了不同环氧树脂涂层的聚对苯二甲酸乙二醇酯（PET）微悬臂梁的杨氏模量。环氧树脂涂料的填料材料是铝和石墨粉末，以不同的百分比与环氧树脂混合。根据挠度计算结果，从理论上计算了材料的杨氏模量。结果表明，随着铝环氧比的增加，PET微悬臂梁的杨氏模量逐渐增大。PET微悬臂梁上的石墨-环氧涂层也显示出相同的趋势。实验结果还表明，在相同配比下，石墨-环氧涂层的杨氏模量比铝-环氧涂层的杨氏模量高。
Young′s moduli of various epoxy coated polyethylene terephthalate (PET) micro-cantilevers were determined from the deflection results obtained using the phase-shift shadow moiré (PSSM) method. The filler materials for epoxy coatings were aluminum and graphite powders that were mixed with epoxy at various percentages. Young′s moduli were calculated from theory based on the deflection results. The PET micro-cantilever coated with aluminum-epoxy coating showed increasing value of Young′s modulus when the ratios of the aluminum-epoxy were increased. The graphite-epoxy coating on the PET micro-cantilever also showed the same trend. The experimental results also show that Young′s modulus of the graphite-epoxy coating is higher than aluminum-epoxy coating in comparison at the same mixing ratio.
