Abstract:

 

Matrix polymer composite materials are increasingly required  especially for high-performance applications.  Sadly, these materials  are subjected to degradation in a given environment.  Indeed, the  aromatic structure of the matrix makes it not only sensitive to the  effects of certain solvents, but also susceptible to the  reorganization of chains over time.  This last phenomenon is known as  ageing and leads to the loss of initial physical and mechanical  properties of the matrix.  Degradation problem due to the exposure to the environment is one of the   most critical affecting phenomena in the use of composite materials in   various structures.  The objective of this work is to present a study of temperature and humidity   effects on plates of polymer matrix materials. The hygrothermal effects are   analysed in a study of water concentration evolution through the plate   thickness (Fick's model). The second part of this work deals with the   determination of water concentrations in composite material plates using a   probabilistic method. It also aims to demonstrate the importance of   probabilistic methods in the field of composite materials and to study   uncertainty regarding the unpredictable variables.
