Resumo: Knitted reinforced single polymer laminate composites based on polyamide 6 (KSPCsPA6) were produced bycompression molding of polyamide 6 microparticlesMPs()PA6powder-coating annealed PA6 Rib or Jersey knittedtextile structures. TheMPsPA6were synthesized by solution/precipitation activated anionic ring-opening poly-merization ofε-caprolactam. The tensile properties ofKSPCsPA6were studied in relation to the knitted re-inforcement architecture,fiber volume fraction, ply orientation and stacking orders. The tensile stiffness andstrength of the newly preparedKSPCsPA6withfiber content of 15% showed significant improvements as com-pared to the neat anionic PA6 matrix and to commercial hydrolytic PA6 (HPA6). The mechanical behavior of theKSPCsPA6was correlated with the geometry parameters of the knitted reinforcements, the polymorph content ofthe samples and their crystallinity indexes determined by differential scanning calorimetry and wide-angle X-raydiffraction. The fracture behavior of KSPCsPA6was investigated by electron microscopy complemented by si-mulation studies.
