註釋It was shown that a single recrystallization of m-phenylenediamine (MPDA) was most effective in generating optimum crack propagation values in the MPDA cured epoxy system. It was also shown that stoichiometric quantities (14.5 phr) of MPDA PROVIDED THE HIGHEST CRACK PROPAGATION VALUES. Fillers were examined and a flat platelets (aluminum silicate) and rounded, granular (zirconium silicate) particles were utilized at various particle sizes and concentrations. The highest crack propagation value was obtained at 50 phr with the 1.5 micron aluminum silicate. As the size of the filler particles increased, crack propagation approached crack propagation indicating that large particles were more effective as crack stoppers in filled adhesive systems.
