MEASURING DEVICE, REINFORCEMENT ROD, PROCESS FOR DETECTING MECHANICAL DEFECTS IN FIBER COMPOSITE BUILDING ELEMENTS AND APPLICATION OF THE PROCESS |
摘要 |
At least a pair (4) or a band of wires of an electrically conducting material is longitudinally embedded in the fiber composite material forming the building element (2) and firmly secured to the fiber composite material over the whole length of the wires. A weak current source (7) is connected to the free ends of the wires. The current conduction is then monitored, the capacitance is measured or the current conduction and the capacitance are measured. |
