CFRP has been applied in various fields where it is mostly used as laminates. CFRP laminates are likely to fracture between the interlaminar surfaces. To resolve this problem, we proposed a self-healing system for CFRP using optical fibers and UV-curable resin. In this study, self-healing CFRP samples were prepared and the effectiveness of repairing the inter-laminar fractures was confirmed by using optical fibers and UV-curable resin. In addition, we have also clarified the factors that affect the repair rate by determining the bonding strength of epoxy resin and UV-curable resin. From the experiment results, we were able to confirm the feasibility of the proposed self-healing system.

Through sensory evaluation, the fabric hands and values of various textiles were ascertained. The relationship between fabric hands and values were also investigated. Two sensory evaluations, comprising of a visual evaluation and visual with tactile (visual-tactile) evaluation, were carried out using verbal expressions that people generally use. When asked to give their judgement about the quality and aesthetics of the textiles used in this study, most of the subjects shared common views. Some of fabric hands were found to be related with the quality and aesthetics values of textiles and the results were similar in both visual and visual-tactile evaluations. Tactile impression is often associated with the fabric hands of the textiles, but in this study, many of the visual impressions of the textiles were found to be similar to the visual-tactile impressions. This study also showed that subjects associated “High-grade” and “Feels beautiful/fine” with the characteristics of the physical properties of the textiles such as bending, compression and surface friction.
