Tough interphases slightly reduce the effectiveness of stress transfer and may be less resistant to water attack, however, they provide significant enhancement of damage tolerance of the FRC part. Moreover, the tough interphases are less sensitive to the direction of the external loading compared to the stiff ones. As it has already been shown, one can design hybrid FRCs with reinforcing fibers coated with both stiff and tough interphases in order to tailor the performance and reliability of the final FRC part. Nano-scale interphase One has to bare in mind, however, that when the length scale considered reaches few nanometers, which is equal to the size of individual polymer chains, the very term ‘‘interphase’’ becomes un-umbigious due to the fact that the discrete nature of the matter has to be taken into account. Originally, the term interphase has been defined in the framework of continuum mechanics. However, the continuum mechanics in the Euler form may no longer be valid on the nano-scale due to very large non-locality in Fig. 5 A typical example of the micro-scale organosilane interphases of various composition deposited on glass fibers using various deposition techniques and translation of the phenomenological properties of the interphases into mechanical response of multifiber compsoites with unidirectiolly aligned fibers 6752 J Mater Sci (2008) 43:6747–6757 123
