N2 - Two sets of unidirectional composites of aramid fibre reinforced Nylon 66 were prepared, by quenching and by crystallizing, respectively. Each set covered a wide range of fibre volume fractions, from 0.005 in microcomposites to 0.65. It was confirmed that the crystallization conditions employed for the crystallized set produced a substantial transcrystalline layer. Mechanical testing of the longitudinal strength and modulus revealed a significant transcrystallinity induced improvement which was fibre-content dependent. That observation was taken as a valid proof of the assumption that an effective contribution of the transcrystalline layer is generated only when the c-axis (chain axis) of the polymer in the transcrystalline layer is parallel to the fibre.
