This work is devoted to the study and predictive modeling of the effects of thermo-oxidation on the mechanical behavior of a polymer (an epoxy resin) and of the associated continuous carbon fiber-based composites.
The study consists of three parts. The first part focuses on the development of specific experimental methodologies such as micro-indentation and interferometric microscopy (i) for the characterization of the local mechanical behavior of the polymer dependent on the oxidation level, and (ii) in the composites for the quantitative characterization of thermo-oxidative induced matrix shrinkage.
The second part develops a local mechanical behavior law dependent on the ageing of the polymer – integrating the inelastic matrix strains of chemical origin and related to thermo-oxidation – based on the thermodynamics of irreversible processes with internal variables (TIV).
Lastly, the book covers the implementation, development and validation of inverse analysis approaches for the identification of the parameters of the local mechanical behavior law of the polymer and of the strains of chemical origin. The identified models are used to calculate the internal stresses associated with thermo-oxidation phenomena in composites.
