Abstract: An abrasive article comprises: a substrate comprising strands forming first void spaces between strands; a laminate joined to the substrate, wherein the laminate comprises a surface opposite to the substrate; a resin composition joined to the surface of the laminate. First and second portions of the surface of the laminate have respective first and second surface free energies that are different. Another abrasive article comprises: a substrate comprising strands forming first void spaces between strands; a laminate joined to the substrate, wherein the laminate comprises a first polymer and a second polymer; a resin composition joined to the laminate; In both embodiments, abrasive particles are joined to the resin composition, and a plurality of second void spaces extends through the laminate coinciding with first void spaces in the porous substrate. A method of making abrasive articles is also disclosed.
