Phenol-formaldehyde resin composites filled with modified phlogopite reinforced with hybrid glass and basalt fiber meshes used as grinding wheels

The research on obtaining composites based on phenol-formaldehyde resin (PFR) with modified phlogopite quaternary ammonium salt (QAS) reinforced with hybrid glass and basalt fiber was carried out. The influence of the reinforcement structure (glass mesh weave) and the type of fiber on the performance properties of the obtained composites were assessed, especially in terms of their use a grinding wheels reinforced with modified hybrid glass and basalt fiber meshes. Based on the obtained research results, it was found that composites reinforced with a glass fiber layer mesh with a matrix of phenol-formaldehyde resin filled with modified phlogopite are characterized by higher mechanical strength, abrasion resistance and dynamic strength of the disk compared to unmodified composites.
