Contexte de travail

At present, the ablative composite materials used in the space industry are primarily based on phenolic resins derived from formaldehyde. With the aim of ensuring sustainability and eco-design, this project seeks to formulate thermosetting epoxy resins derived from bio-based phenols as substitutes for phenolic resins, in accordance with specific requirements defined by the industrial partner. The targeted applications concern rocket nozzles developed by ArianeGroup, which are subjected to intense aerothermal fluxes. Bio-based resins developed specifically for this project will be formulated to produce composite materials capable of maintaining high performance at elevated temperatures. Additives such as flame retardants may be incorporated to tailor the material properties. Achieving a high carbon yield and optimising the resin processing will be key objectives of this study.
This post-doctoral position is part of a collaboration between LCPO and the companies ArianeGroup and GTT, offering a stimulating scientific environment at the interface between academic research and industrial innovation. This collaboration takes place within the framework of an industrial ANR Chair: the SPACE-MAT project (Sustainable Polymers for Advanced Materials in Aerospace and Transport)
