Erosion of Composite Resins

The surface degradation of composite resins caused by accelerated aging was studied. Accelerated aging for 900 hours caused erosion of the resin matrices and exposure of filler particles. Differences in surface profiles after aging suggest that the materials eroded at different rates. Accelerated aging may model erosive wear of composites.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/67987/2/10.1177_00220345800590051101.pd
