4.8 Summary of Results for Multiphase Composites
It is useful to bring together the results that have been derived for multiphase fibre-reinforced composites. The values of the effective properties κAeff, κTeff, EAeff, ETeff, νAeff, νteff, kTeff, μAeff, μteff, αAeff and αTeff of the transverse isotropic unidirectionally fibre-reinforced composite may be obtained from the following set of formulae, obtained from relations (4.10), (4.13), (4.66)–(4.69), (4.91), (4.147), (4.152) and (4.160)
