The HTT treatment consisted of subjecting the WS particles to a steam explosion process for 8 min at 180 degrees C. The HTT and UT WS particles were mixed with the wood particles at 10, 20, 30, and 40% ratios. The physical properties, including density, water absorption (WA), and thickness swelling (TS), were determined for the bio-based composites. The mechanical properties evaluated included the modulus of rupture, modulus of elasticity, and internal bond strength. Statistical analyses showed that the hydro-thermal treatment and the WS ratio had significant effects on the dimensional stability and mechanical properties of the bio-composites. The WA of the composites after 2-h and 24-h rose significantly when the HTT WS particle ratio was increased from 10 to 40%. The 2-h and 24-h WA values of HTT10 were 6.3% and 5.3% lower than those of UT-10, respectively. Improvements in the 2-h TS value were achieved by the HTT WS particles at the 10% ratio, and in the 24-h TS value at the 10 and 40% ratios. The mechanical properties of the composites were higher in the HTT group, but decreased in both the UT and HTT groups as the WS ratio increased.en10.15376/biores.16.4.7901-7915info:eu-repo/semantics/openAccessHydro-Thermal Treatment; Composite; Wheat Stalks; Dimensional Stability; Mechanical PropertiesHelianthus-Annuus L.; Raw-Material; Physical-Properties; Needle Litter; Bonded Reed; Particleboard; Wood; Manufacture; Suitability; HuskArticle164790179152-s2.0-85137271909WOS:000748249200002Q3Q2
