Influence of Resin Content on Composite Materials Railway Sleepers for Physical and Mechanical Properties
It studies the influence of resin content on composite materials railway sleepers for physical and mechanical properties,which is for the preparation of composite materials railway sleepers.It used resol resin setting hot pressure at 2.5Mpa, hot pressing temperature at 170°C, pressing time at 5-6min. The results showed that as the resin content increases, the static bending strength (MOR) first increased and then decreased, the internal bond strength (IB) rised, 2h thickness swelling (2h TS) decreased. Through the analysis of experimental data by using DPS data processing system, resin content had a significant impact on 2h TS.It also affected MOR, IB.But it had little effect on measured density (D), water content (W) and impact strength (IL).
