Models proposed so far for the relationship between mechanical strength (stress to fracture) and filler content (volume fraction) of rigid matrix particulate composites are briefly reviewed. In the case of no adhesion between matrix and filler particles, for which regular, semiregular and random models have been formulated, a new semiempirical equation, based on the more realistic random structural view, is suggested as an attempt towards a unifying treatment of the subject. It is also shown that the same equation, properly modified on purely empirical grounds, can be used when adhesion between matrix and filler is present. |
