摘要
针对碳纤维增强塑料的纤维取向测量中制样复杂、基体和纤维对比度不高的现状,提出了基于叉指电容的纤维取向介电测量方法。本文建立了各向异性材料的介电-取向理论模型,完成了叉指电容(IDC)传感器的结构设计与优化,最后通过单向碳纤维增强聚醚醚酮(CFR/PEEK)板材的电容测量实验和超景深显微观测结果,验证了该方法的可行性。
A new fiber orientation measurement method was proposed based on dielectric anisotropy for the reason of tedious sample preparation procedures and inconspicuous contrast between the fiber and the matrix. In this paper, the dielectric-orientation measurement mechanism of anisotropic materials was theoretically derived. Then the structural design and optimization of interdigital capacitor( IDC) sensor were completed. Experimental verification was conducted by the capacitance measurement of uniaxial carbon fiber reinforced polyether-ether-ketone( CFR/PEEK) and the observation of super deep scene 3 D microscope.
