摘要 The dissipative processes occurring in rosin of rosin–copper and rosin–cellulose composite systems have been studied by dynamic relaxation spectroscopy at temperatures from –150 to +250°C. Internal friction spectra and temperature-frequency dependences were obtained for pine and tall oil rosin. Regions of inelasticity caused by local dissipative processes were determined in rosin and used to substantiate increased wear resistance of rosin-containing composite materials.
