Abstract

Strengths of a composite when determined by actual tests shows a lower value than those obtained through theoretical estimation by applying the simple rule of mixtures. This discrepancy has been attributed largely to the presence of defects in the composite like debonding, porosities, cracks etc. To establish a design criteria to a more practically closer strength values an empirical formulae is presented. The formulae accounts for defect level upto 30%. The results were obtained through computational facilities using IBM (360/44) Computer. The drop in strength with increasing defect level is shown to occur and the effect is more predominant when defects are more in fibres than in matrix.
