abstract

Three-dimensional components which incorporate CFRP are molded by skilled workers manually. This makes quality control difficult. In this study, we aim to establish standardization of work and set a standard of quality examination. We focus on the eye movement to examine that the differences of worker’s proficiency level influence on the hand lay-up process. Carbon cloth prepreg was stacked in three layers in the mold. The fiber orientation of the carbon cloth was set using one edge of the mold as the plane of reference. The first layer was 0°, the second was 45°, and the third was 0°. The hand lay-up process was applied and subjects chose their own process and tools. Subject A had 13 years of experience, subject B had 1 year of experience, and subject C had no experience. The process was recorded with a video camera and results compared in an interview format, inspecting footage of the process together with the subject. Subject A’s movements were very smooth, his body and face close to the mold, whilst subject B’s movements were very awkward. Subjects’ use of tools and hands were analyzed. In the mold used for this study, there are roughly three elements. In order to obtain flat smoothness in corner R and the four deep corners of the edge, a high degree of skill was required. A significant gap in mechanical dexterity was clearly observed between an expert and beginners. We will repeat this study on a constant basis with more subjects, and further clarify the elements.
