視する電極装置に関する。Generally, when manufacturing resin-based composite structures, it is known that high-quality structures without internal defects can be molded by applying heating temperature and pressure conditions that match the curing progress of the matrix resin. For this reason, this device is designed to electrically monitor the progress of resin curing without applying air energy, and is particularly designed to monitor resin whose viscosity has decreased during the curing reaction process. Detects a type of electrochemical electrode voltage (hereinafter referred to as curing reaction voltage) that occurs between the metal electrode and changes its value as the resin hardens, thereby monitoring the progress of resin hardening. The present invention relates to an electrode device.

あられれる電位差を測定することによって行われていた
が、これらの方法は、以下述べるような欠点を伴ってい
た。Conventionally, this curing reaction voltage was measured by attaching two metal plates to the front and back surfaces of the molded product, or by inserting two metal wires into the molded product in parallel to serve as electrodes. This was done by measuring the potential difference between the electrodes, but these methods had the following drawbacks.
即ち、コ個の電極板を成形物の表裏に貼りつけるには、
先づ、一方の電極板を成形治具面に貼り決めが困難で、
作業性が悪いとともに、電極間距離が数Ｕを超えると、
静電気などによる電気雑音が混入し、測定精度が著しく
悪化してしまう問題点がある。In other words, in order to attach the electrode plates to the front and back of the molded product,
First, it was difficult to attach one electrode plate to the molding jig surface.
In addition to poor workability, if the distance between the electrodes exceeds several U,
There is a problem in that electrical noise due to static electricity etc. gets mixed in and the measurement accuracy deteriorates significantly.

った。Also, if several electrode wires are inserted in parallel into the molded product,
Detection sensitivity is low because it is difficult to secure a sufficient contact area between the resin and the electrode, and if the reinforcing fibers of the composite material are conductive,
It is very difficult to avoid short circuits caused by contact between the fibers and the electrodes, and it is also difficult to remove the electrodes after curing without damaging the molded product.

きる装置を提供せんとするものである。The present invention has been made in view of the above circumstances, and uses simple and rational means. Specifically, the present invention provides a long and flat electrode and an external lead terminal on one side of an electrically insulating substrate. In addition, by configuring the above-mentioned spear 1 and spear 2 electrodes with different metals, the problems of the conventional technology can be solved, noise generation due to static electricity can be reasonably prevented, and measurement accuracy and reliability can be improved. It is an object of the present invention to provide a device that can improve the performance of the molded product and detect the progress of curing using only the upper surface of the molded product on the molding jig.

is a substrate made of an electrically insulating material, and on one side of the substrate (1), a flat spear/electrode (2) that is elongated and has a certain width is provided. Adjacent to the spear electrode (2), a flat spear electrode (3) with a certain width is placed along both longitudinal sides of the spear electrode (2).

The substrate [1] is attached to the surface of the molded product (path shown) stacked on the molding jig (path shown) so that the surfaces of the second electrodes (2) and (31) are in contact with each other. If necessary, fix the substrate (11) to the surface of the molded product using adhesive tape or the like, and connect the lead wires (4) and (5), or (4) and (6), as the process of bonding and separating progresses. When the viscosity of the matrix resin decreases and becomes fluidized, the resin and the two electrodes (2), (2), (
During 3), a curing reaction voltage corresponding to each metal is generated, and the potential difference can be continuously measured by the voltmeter or recorder mentioned above throughout the curing process of the resin.

とができるので、作業性が格別に良くなる。In this case, since the spear/electrode (2) is surrounded by two spear electrodes (3), generation of static electricity voltage gradient is suppressed, and highly accurate curing reaction voltage detection is possible. A higher voltage can be obtained than when the electrode rods are simply arranged in parallel, as in the conventional case. Furthermore, since this electrode device (Al) can detect the curing reaction voltage simply by attaching it to one side of the molded product, the workability is extremely improved.

As shown by the imaginary lines in Figure 3, it is best to cover and fix with an electrically insulating and heat-resistant woven fabric (7). In this way, the fluidized resin will penetrate through the woven fabric (force weave),
Although it can come into contact with the spear lambda electrodes (2) and (3), the reinforcing fibers do not come into contact with the hair and tooth electrodes (2) and (3), so there is no short circuit.

It is convenient to use a woven fabric that has good releasability from the resin because it facilitates the removal of the electrode device (1), specifically the substrate (1), after curing.

It showed a characteristic change tendency depending on the molding temperature conditions and the type of matrix resin, and it was possible to fully correlate it with the change tendency of resin viscosity during the curing process.

度の硬化反応電圧の測定が可能となる特長がある。As explained above, the electrode device (m) of the present invention has the following problems:
Since the spear electrodes are made of different metals, the difference in electrode voltage that occurs between each electrode and the resin can be detected as the curing reaction voltage of the resin. Therefore, the curing of the resin can be performed without using an external power source. The reaction situation can be monitored electrically, and 2.
Since the two electrodes are arranged so as to closely surround the 2.l electrode, it has the advantage of preventing the generation of noise due to static electricity and making it possible to measure the curing reaction voltage with high accuracy.
