Shear strength interfacial bulk

Applying this model to MWNT/PVA composites resulted in a predicted interfacial shear strength, t, of 348 231 MPa, about an order of magnitude higher than expected. Thus, Eq. (35.5) was modified to allow for the observed interfacial failure at the boundary between the bulk polymer and the ciystalline polymer layer (thickness = b) adhering to the MWNT surface. 

The wetting kinetics of sized glass fibers by melt changed due to acid-base interactions and compatibility between the film former and surrounding bulk polymer matrix. The highest interfacial shear strength values corresponded to the... 

Fig. 1 Schematic description of cohesive and interfacial wear processes from the two terms non interacting model of friction (from [96]). Bulk ploughing involves the dissipation of the frictional work within a volume of the order of the cube of the contact radius. Interfacial shear corresponds to the dissipation of the frictional energy in much thinner regions and at greater energy densities. Cohesive wear processes (cracking, tearing, microcutting...) are governed by the cohesive strength of the polymer. Mechanisms such as transfer film formation correspond to interfacial wear and do not readily correlate with accessible bulk failure properties...
