Abstract
Spray up fabrication has been used for forming composite structures since ancient times as it can be performed as long as the mold, skills, and materials are available. Hence highly specialized control technique and the tradition of skill are required to ensure the consistent stability of product quality. In this study, the authors thus conducted a motion analysis experiment using hand lay-up fabrication experts as subjects. The experiment, seemingly a new and only attempt in Japan, quantified techniques that are not visibly apparent and considered to be tacit knowledge. The dimension stability of samples was measured, and their relationships with the motions of experts were also evaluated. It was also suggested that highly specialized control techniques, the appropriate training of non-experts, and technical tradition are possible.
