Durability thermodynamic considerations

Many industrial composite materials contain both fibres (often of different type or form) and particulates, so that their interaction with an environment can be complex. In order to discuss these issues, a simplistic approach will be used to indicate how a durable material can be achieved. One of the most important aspects is the chemical inertness of the polymer matrix. For most purposes, aqueous environments are of greatest significance and they will form the main part of the discussion in this chapter. In the case of non-aqueous environments, thermodynamic considerations can be used to assess the resistance of the matrix to solvent attack.
