| Outline of Final Research Achievements |
Aramid fiber reinforce plastic (AFRP) with high mechanical strength, impact residence and lightweight is used such as repair and additional of structures. However the current recycling techniques are limited to landfill because it contains thermosetting resin such as epoxy resin. Therefore the proper recycling of waste AFRP is necessary. In this study, a new recycling technique of AFRP using supercritical fluid was studied. Epoxy resin in AFRP was decomposed using supercritical acetone. The aramid fiber was recovered from AFRP and examined for the mechanical strength. As compared with the virgin aramid fiber, the tensile strength of the recovered aramid fiber was reduced by 35%. On the other hand, the cut-through resistance did not change. As a result, the optimum conditions of the decomposition of epoxy resin in AFRP were use of acetone, 320oC, 10MPa and 7 min of reaction time.
