Abstract

With the development of microelectromechanical system (MEMS) technology, the limitations of machining technology for silicon-based materials become more and more distinct. With its abilities on sub-micron structure machining, the pulsed laser micro-fabrication technology has an extensive application prospect in MEMS and many other materials. The thermal interaction process of polymer under laser irradiation is very complex, regularities on polymer target under laser irradiation between displacement and laser energy density can only be obtained through experiments. Based on finite element method (FEM), simulations have been performed and compared with experiment results. Relations among pulsed laser intensity, actuation duration and thermal shock loads were obtained from the comparison, and a formula for calculating the maximum ablation pressure of a carbon fiber epoxy resin polymer composites was proposed. This study provides theoretical basis to the pulsed laser micro-fabrication technology's application in the fields of MEMS.
