Characterization of traditional and fast-curing aeronautical material systems
Customer name :
Strategic material supplier: Syensqo; Major aerospace OEMs; Major aerospace Tier-2s
Completion date : 2020-2025
In brief
Characterization and modeling of traditional and fast-curing aeronautical material systems using our state-of-the-art instrumentation and materials science expertise.
Project summary
For our customers, we have characterized a wide range of thermosetting polymer matrix material systems, including prepreg systems for press, autoclave or out-of-autoclave molding, as well as aerospace-grade resins used in the context of injection (RTM) or vacuum infusion (VARI) processes. To achieve this, we drew on our fleet of state-of-the-art materials characterization instruments (DSC, rheometer-DMA, TGA and TMA) and customized data analysis tools. Subsequently, we developed predictive "materials" models that enabled our customers to simulate, adjust and optimize their composite manufacturing processes, regardless of the targeted implementation process. This modeling of the "in-process" behavior of composite materials was made possible by our expertise in thermochemistry, chemo-rheology and thermomechanics of polymers. Ultimately, we were able to deliver predictive analytical models to our customers, in the form of user-friendly MS Excel spreadsheets that can be queried directly and quickly by the user.
