Abstract:

Isolated microfibers and isolated microflakes do not contribute to strengthening of the composite material. Stress concentrations arising at the ends of isolated microelements will easily reach proportions threatening to destroy the surface bond between microelement and matrix. Whenever this happens the end portions of the microelements become totally inactive. The same kind of inefficiency is inherent in a sequence of microelements aligned along a common line plane. Such arrangements will not help to build a strong composite material. It was intuitionally recognized, and has now been confirmed by mathematical elasticity analysis that the basis of strength of the composite lies in the staggered arrangement as shown in illustrations in the report and in force transfer by means of shearing stresses.
