Assessment of the Microstructure and Mechanical Properties of a Laser-Joined Carbon Fiber-Reinforced Thermosetting Plastic and Stainless Steel

Abstract

The thermosetting plastic and stainless steel were joined with a fiber laser. The influence of processing parameters on the joint was studied. The laser scanning on stainless steel is shown to result in the formation of the heat-affected and fusion zones. In the first zone, lathy ferrite precipitates along the boundary, which modifies austenite, while in the second zone, ferrite forms the skeleton structure and separates austenite into a small cellular structure.

Выполнено соединение реактопласта и нержавеющей стали с помощью волоконного лазера. Изучено влияние технологических параметров на качество соединения. Показано, что сканирование поверхности нержавеющей стали лазерным лучом приводит к образованию зон термического влияния и проплавления.
