7 April 2009 Monitoring and modeling the diffusion profile in a thermosetting resin
Author Affiliations +
At the previous SPIE conference in San Diego (2008), the authors presented and compared a range of low-cost optical fibre sensors for monitoring the cross-linking process of a thermosetting resin. The same sensor was used subsequently to monitor and quantify the diffusion of water in the cross-linked polymer. The current paper presents recent data on the deployment of an array of low-cost fibre-optic sensors to monitor the water diffusion front. The data obtained from the sensors are compared with conventional gravimetric measurements and theoretical predictions for the diffusion profile for water ingress in a cross-linked epoxy/amine resin system.
