Process study of hand lay-up method to clarify implicit knowledge of professionals

Abstract

Hand-lay-up method is superior as the molding method for FRP in terms of small lot production of many products. However, there is potentially the problem that mechanical property of molding products depend on technique of workers. Therefore, if tacit knowledge those experts have, early growing of that non-experts and automation of hand-lay-up method are hoped. The purpose of this study is to clarify the tacit knowledge and to change it explicit knowledge. In order to this purpose, process analysis, measurement of thickness and pressure of molding production and many subjects were examined to clarify correlation to mechanical properties. As a result, it was established that the guide of technique for hand-lay-up enabled non-expert to mold the FRP which has similar mechanical property to expert by clarifying the explicit knowledge of experts.
