The nature of a fiber-matrix interface plays an important role in the mechanical properties of composites, such as their strength and toughness. In a casting fabrication route, discuss the issue of the bonding between fibres and matrix if the surface tension (C) between the solid (S), Liquid (L) and Vapour (V) are expressed as follows; OSL=oLv+osv-(1.55 – 14.38exp(-0.0029T)) VOLVOSV OLV = 875 – 0.18(T – TM) = 1043 – 0.18T (mNm-?) Osv = 2077-0.7083T The matrix alloy is aluminium and the fabrication temperature (T) is superheated to 100°C above the melting point of aluminium (TM), which can be found in your lecture notes.
