“…The wear on the glass-fiber polyester composite decreases due to the effect of increasing temperature removal from the surface as illustrated. The epoxy-based composite exhibits lower wear loss than that of polyester-based composite [18,20]. The mass loss is lower in glass fiber-epoxy resin composite specimens than in fiberglass-polyester resin composite under 0,390 m/s speed and 5N load according to the sliding distance in Fig.…”

“…When the temperature increases from 10 • C to 35 • C, the MDD increases by 0.052 kg/m 3 and the OWC decreases by 0.26%. This is mainly because the increasing temperature leads to the content of sodium sulfate solution increasing, which reduces the friction between the aggregates, makes the aggregates cemented tightly [32][33][34]. In this condition, the CSMBM can be compacted at low water content.…”

This paper describes an experimental investigation into the compaction characteristics of cement-stabilized macadam base materials (CSMBM) in a saline soil area. Through the field tests, the main causes of arch expansion in an existing road were analyzed. Based on this, the compaction tests and microscopic tests were designed to analyze the impacts of temperature, sodium sulfate content and cement content on the compaction characteristics of CSMBM. Then, the orthogonal test was designed to analyze the effects of the degree of the temperature, the cement content, and the sodium sulfate content on the compaction results of the CSMBM. Feld tests results show that the temperature, sodium sulfate content and cement content may be the main causes of arch expansion. The compaction tests show that with the temperature increasing, the optimal water content (OWC) decreases, but the maximum dry density (MDD) increases; with the sodium sulfate content increasing, the OWC increases, but the MDD decreases; with the cement content increasing, both MDD and OWC increase. The microscopic tests show that the increase of temperature and cement content is beneficial to the compactness between cementitious materials and aggregates, while the increase of sodium sulfate content makes the whole structure of cementitious materials and aggregates increasingly rough. The orthogonal test shows that the temperature has the greatest influence on the MMD, and the sodium sulfate content has the greatest influence on the OWC. Thus, in a sulfate saline soil area, the construction temperature, the sodium sulfate content and the cement content should be controlled to ensure the compaction quality of CSMBM.

“…The polymers can be shaped by molding, extrusion or machining [5]. Many polymers are widely used in sliding coupling against a metal [6][7][8][9][10][11][12][13][14], polymer or other materials; they are used as pure materials, polymer composite [11], composite polymer metal, coating, solid lubricant, and thin monolayer [15][16][17][18][19].…”

The Tribological behavior of Polystyrene Crystal disc sliding against a steel 100Cr6 ball with a radius of 5mm over a range of loads (1-5N) and speeds (12.5-63mm/s) was investigated using a ball-on-disc tribometer under unlubricated conditions. All the specimens were used as obtained from injection molding. For this purpose, we monitored the evolution of the friction coefficient and the wear rate as a function of sliding speed and normal load applied. The worn surfaces were examined by Scanning Electron (SEM) and optical microscope. Several wear mechanisms were observed: plastic deformation, abrasion in the track, and adhesion at the edge of the track. The mechanisms were found to depend on speed and load. The wear rate is of the order of 10-2mm3/N.M, which may explain that the wear is of a severe type.
