Distribution of Carbon fiber (CF) in the composites matrix has a considerable effect on the functional properties to the composite material so it is necessary to research the electro-mechanical response of carbon fiber under off-axis tension. Two important perpendicular strain variables, strain along the CF orientation and strain vertical to CF, were found to be correlated with the CF resistance response under off-axis tension. The ratio of resistance change could be predicted quantitatively and simultaneously by a multivariate functional approach using multiple linear regression (MLR) in the procedure of data mining. The methodology proposed provides a means of simultaneously estimating the two perpendicular strains by CF resistance response tested instead of traditional strain gauge.
