FIELD: chemistry.
SUBSTANCE: surface treatment of the fibred reinforced fillers is carried out with the solution of phenol-formaldehyde resin of resole type and non-ionic surfactant in isopropanol with slow stirring in the vacuum reactor. Further drying under the vacuum is carried out until the isopropanol is completely removed.
EFFECT: processing quality improvement.
