Abstract
Example embodiments relate to methods and systems for generating and using abrasive articles. An abrasive article includes an open cell foam body and an abrasive composition disposed homogenously throughout the open cell foam body. The abrasive composition includes a resin and a plurality of abrasive particles, where each abrasive particle has a threshold hardness (e.g., a hardness of at least 6 on a Mohs scale). As such, the abrasive article has an effective grit that depends on a pressure applied to the article and can have a variable grit that depends on the properties of the open cell foam body and abrasive particles.
Claims17
An abrasive article comprising:
- an open cell foam body;
- and
- an abrasive composition disposed homogenously throughout the open cell foam body, wherein the abrasive composition comprises a resin and a plurality of abrasive particles,
- wherein each abrasive particle has a hardness above a threshold hardness level;
- wherein the abrasive article has a pressure dependent effective grit and a pressure independent average grit wherein the pressure dependent effective grit is lower than the average grit at a pressure of greater than 3.75 kPa and wherein the pressure dependent effective grit is greater than the average grit at a pressure of less than 3.75 kPa.
