FRP and the FRP of non-destructive inspection equipment

摘要

PURPOSE:To preliminarily grasp the fatigue state of FRP with high accuracy by arranging carbon fiber aggregates in FRP in an almost matrix-like state and providing electrode terminals to both end parts of each of the carbon fiber aggregates. CONSTITUTION:A measuring device 102 can measure the resistance value between carbon fiber aggregate 12 and a memory device 104 storing the resistance values measured by the measuring device 102 at every carbon fiber aggregates 12 is provided. A microcomputer 106 compares the resistance value of each of the carbon fiber aggregates 12 with that of each of the carbon fiber aggregates 12 newly measured by the measuring device 102. This compared value is compared with a preset value and, when the compared value is equal to or more than the preset value, the coordinates code of the carbon fiber aggregate 12 is displayed on a display device 108.
