Fabrication of Unidirectional Whisker reinforced Micro Part

本文研究了用激光光刻法制备单向晶须增强微结构零件。在该方法中，通过向液态光聚合物和晶须的混合物施加直流电（DC），使晶须的轴沿着电场的方向排列。在施加直流电的过程中，通过UV激光束写入使聚合物固化。用该方法制备了单向晶须增强聚合物微构件。光聚合物固化期间的收缩导致激光光刻中的制造误差。具有单向晶须的聚合物的拉伸强度也增加。

This research work deals with the manufacturing of unidirectional whisker reinforced micro part by laser photolithography. In this method, by applying direct current (DC) to a mixture of liquid photopolymer and whiskers, the axis of the whiskers is aligned along the direction of the electric field. The polymer is solidified by UV laser beam writing during the application of the direct current. Micro parts of polymer reinforced by unidirectional whiskers are produced by this method. Shrinkage during the solidification of the photopolymer causes manufacturing errors in laser photolithography. The tensile strength of the polymer with the unidirectional whiskers also increases.
