采用梯度功能材料力学方法, 通过改进层合板理论模型来预测材料的力学性能. 将饱和掺杂金属原子的外层作为表面镀层, 将无掺杂的基体作为中间层, 两层之间掺杂的金属原子含量逐渐变化, 作为梯度层;使用EDS方法得到了Pt型金属/离子聚合物复合材料(IPMC)沿厚度方向的Pt原子含量分布, 证明了模型分层的合理性;采用ASTM标准测定了IPMC材料的拉伸和弯曲弹性性能. 本模型采用Mori-Tanaka方法预测表面镀层和梯度层的弹性性能, 采用梯度力学方法, 最终得到IPMC材料整体的弹性性能. 用本文中模型预测常态下和含水饱和态下的IPMC拉伸性能与实验值相比, 误差分别为0. 69%和-2. 05%;预测常态下IPMC的表观弯曲弹性模量与实验值相比, 误差为-0. 99%.
An improved model of lamination theory was used to forecast the mechanical properties of ionic polymer metal composite(IPMC). The outer layer doped with saturated metallic atoms was used as the exterior plating layer, the pure polymer was used as the middle layer, and the material between the two layers, in which the metal content gradually varied, was a gradient layer. Because of Pt content in thickness of Pt-IPMC was detected using EDS method, the rationality of the model was proved. The tensile and bending modulus were tested by the ASTM standards. The elasticity properties of the outer and the gradient layers were predicted by Mori-Tanaka method. and the properties of IPMC were obtained by using gradient mechanics. The tensile performance of IPMC under normal and saturation conditions was estimated and compared with the experiment results, the error of tensile module under normal and swelling conditions is 0. 69% and-2. 05%respectively, while the error of apparent bending module under normal conditions is -0. 99%.
