ている。[Prior art and its problems] In general, when molding and manufacturing resin-based composite structures, it is possible to produce high-quality materials without internal defects by applying heating temperature and pressure conditions that match the curing progress of the matrix resin. It is known that structures can be molded, and for this reason various methods have been investigated to continuously monitor the progress of resin curing.

は、以下述べるような課題を伴つていた。 Conventionally, this curing reaction voltage has been measured by attaching two metal plates to the front and back surfaces of the molded product, or by
This was done by inserting two metal wires parallel to each other into a molded product to serve as electrodes, and measuring the potential difference that appears between the electrodes, but these methods have the following problems: He was accompanying me.

いう課題がある。 That is, to attach two electrode plates to the front and back sides of a molded product, first attach one electrode plate to the surface of the molding jig, then laminate prepreg on top of it to the required thickness. In addition, the other electrode plate must be attached to the top surface of the laminate, making it difficult to position both electrode plates, resulting in poor workability.If the distance between the electrodes exceeds several mm, electrical noise due to static electricity etc. may be generated. There is a problem in that the measurement accuracy is significantly deteriorated due to contamination.

つた。 In addition, when two electrode wires are inserted in parallel into a molded product, it is difficult to ensure a sufficient contact area between the resin and the electrodes, resulting in low detection sensitivity.Also, if the reinforcing fibers of the composite material are conductive, It is very difficult to avoid the short circuit caused by contact between the fiber and the electrode, and it is also difficult to remove the electrode after curing without damaging the molded product.

Furthermore, this electrode device A can detect the curing reaction voltage simply by attaching it to one side of the molded product.

A voltage change in which the generated voltage reached a maximum and then gradually decreased could be clearly detected. This curing reaction voltage showed a characteristic change tendency depending on the molding temperature conditions and the type of matrix resin, and it was sufficiently possible to correlate it with the change tendency of resin viscosity during the curing process.
