Resin Behaviour During Processing: What are the key resin properties to consider when developing a manufacturing process?

During manufacturing the resin undergoes significant transformations: thermoset resins evolve from a low molecular weight liquid to a highly cross-linked solid. A thorough understanding of this liquid-to-solid transition is critical when developing, optimizing or troubleshooting a manufacturing process. For example, the impregnation and consolidation of the fiber bed must be completed before the resin transforms from a viscous liquid to a rubbery gel, and demolding must happen when the resin reaches a glassy solid state.

This webinar will discuss the key manufacturing properties of thermoset resins such as viscosity, gelation, glass transition temperature, and degree of cure. Short videos will be used to demonstrate the different techniques used today to characterize these manufacturing properties. The content of this webinar will be extracted live from the Knowledge in Practice Centre (KPC) – an open resource for composites manufacturing knowledge and best practices, available online at https://compositeskn.org/knowledge-in-practice-centre/.
