Abstract: The invention relates to hybrid fabric comprising: a high-performance polyethylene (HPPE) fiber having a tensile modulus of at least 110 GPa, preferably higher than 135 GPa, as measured according to ASTM D885M-2014; and a non-polymeric fiber, wherein the cross-sectional area of the HPPE fiber is equal to or smaller than the cross-sectional area of the non-polymeric fiber, the cross-sectional area being defined as the linear density of the fiber divided by volumetric density of the fiber. The invention also relates to a composite comprising the hybrid fabric and to an article comprising the composite.
