Abstract

Longitudinal strength σc of an epoxy reinforced with one layer of long aligned and equally spaced glass fibers has shown that for a certain fiber spacing λ, σc√λ = κ, where κ is a constant. A similar expression was suggested for the strength of a borosilicate glass - SiC fibers composite under bending and the maximum fiber spacing. Steady crack growth under fatigue was observed in the glass - epoxy system. Using experimental data and a simple analysis, the forces on the fibers in the bridging zone were found equal. Analysis indicated that the total stress intensity factor was constant at the steady growth mode. Power relations were used to correlate steady speed with the stress intensity factor and the rate of debonding with the applied stress.
