Monitoring method of damage in hole processing of carbon fiber reinforced plastic.

摘要

The present invention is a carbon fiber reinforced plastic, two electrodes disposed at a predetermined distance apart from the carbon fiber reinforced plastic and a conductive line is connected to prepare a specimen, A database (DB) construction step of drilling a plurality of holes, measuring the resistance change of the electrodes according to the hole drilling, and storing data on the change in resistance, two electrodes in carbon fiber reinforced plastic spaced a predetermined interval A manufacturing step of manufacturing a test carbon fiber reinforced plastic having the same structure as the test specimen by arranging and connecting a conductive line. A single or multiple holes are drilled in the test carbon fiber reinforced plastic, and the test carbon fiber Reinforcement of the test carbon fiber by comparing the resistance measurement step of measuring the resistance change by supplying current to the electrodes of reinforced plastic and the resistance measured in the resistance measurement step with the data on the change in resistance prepared in the database building step It provides a method for monitoring damage during hole processing of a carbon fiber reinforced plastic, comprising a monitoring step of determining whether a hole perforated in the plastic meets a required condition. Therefore, by measuring the resistance that changes due to the hole processed in the carbon fiber reinforced plastic, it is possible to know whether the hole has been processed suitably to the required condition.
