Název v původním jazyce

Epoxy resin curing monitoring in industrial production

Popis výsledku v původním jazyce

The online monitoring of resin curing process is described in the presented artícle. There exists several monitoríng technique useful for resin curing monitoring and consequently for the curíng technology improving, at the present. The advantage of the descríbed monitoring system and monitoring method is in the using a uníque sensors directly inserted into the tested resin or technology part which allows observing the resin characteristics as well as the local temperature directly at the sensor area. The data acquisition ís processed by the in-house developed portable curing monitoring device and wirelessly transferred to the PC for further analysis. The study describes the experimental work of using the monitoring system and sensors and also the curing process of resins and composites using electrical mpedance magnitude. There are identífied and described the typical phase transitions of resin as lowest viscosity point, gel point and vitrification of the cured system. These points are necessary to know online for curíng process control. The monitoring system could be useful for pure resín diagnostics as well as for the fibre reinforced composites even for fibre reinforced composites using conductive fibres (for example carbon fibres). The developed system is more sensitíve than RLC method.
