本研究利用積層製造的方法製作出複合材料來探討異質材料機械性質，使用聚合物噴射(PolyJet)光固化成形的列印方式列印出軟質硬質材料的疊層試片，首先軟質材料以黏彈材料為模型，利用拉伸試驗以及應力鬆弛得到所需的參數，再將參數匯入於有限元素分析建立出黏彈模型使用的Prony series，接著利用動態實驗來撞擊雙材料的試片，量測結構振動頻率，再將所得到的頻率套入白努利-尤拉樑理論反算楊氏係數，接著利用有限元素分析模擬自然共振頻率以及利用動態撞擊模擬，分別驗證實驗的準確性以及黏彈材料的動態特性，由相互比較的結果可以清楚的發現，本研究的模型在有無考慮黏彈特性的情況下可以得到明顯的差異性，黏彈材料在低頻時因為較容易吸收震動而剛性較弱，反之在高頻時不易吸收震動而剛性較強，本研究也利用多種不同軟硬程度組合的黏彈材料複合硬質材料模型來驗證此特性，並比較對稱與非對稱異質材料組合以及不同材料厚度比來比較之差異性。

In this study, the hard and soft compounded, additive manufacturing is used to investigate the mechanical properties of composite materials. We use PolyJet method to print soft and hard material as the composite structural beam. First, the soft material with viscoelastic property used the tensile test and stress relaxation to obtain the parameters, and then using the parameters import the finite element analysis to establish Prony series, using dynamic experiments to impact the composite-material specimen, the equivalent elastic constant is measured by inversely calculation from the first natural mode, according to the Euler–Bernoulli beam theory. Recalculating by the finite element analysis to simulate the natural frequency and use dynamic impact simulation, the accuracy of the experiment measurement was verified in the dynamic properties of the viscoelastic material.
Viscoelastic materials at low frequency has a lower rigidity because of vibrating absorption. Contrary, the viscoelasticity at high frequency has a higher rigidity. This study also uses the differently compounded models to verify the dynamic characteristic of material property, The difference between symmetric and asymmetric heterogeneous materials, and different thickness ratios, respectively, is also discussed on the applicability material properties in accurately of structural natural frequencies.
