The main objective of this study was to evaluate the dynamic mechanical thermal analysis (DMTA), mechanical, physical and wettability properties of hybrid composites developed from sustainable green materials, jute fiber and wood particles that were manufactured by using the vacuum-assisted resin transfer molding technique. The storage modulus, loss modulus and tan δ values of the hybrid composites were also determined to evaluate the DMTA performance. The results showed that the storage modulus of jute/polyester resin is superior to those of the jute–wood/polyester hybrid and wood/polyester up to the glass transition temperature (T _g). However, for temperature ranges higher than T _g, the stiffness of hybrid composites increased relatively. The T _g values from loss modulus and tan δ peaks support this effect of hybridization. Tests on mechanical properties showed that the jute/polyester specimens had a significant increase in tensile strength compared with the jute–wood/polyester hybrid and wood/polyester specimens. The results of tests of physical properties showed that the wood/polyester specimen had the lowest values of thickness swelling, water absorption and moisture content compared with the jute/polyester and jute–wood/polyester composites. The highest contact angle was obtained from composites made of wood/polyester. It could be concluded that the composites with enhanced performance could be used as novel green composites in various sectors.

可持续绿色材料混合复合材料的开发和表征

本研究的主要目的是评估由可持续绿色材料、黄麻纤维和木质颗粒开发的混合复合材料的动态机械热分析 (DMTA)、机械、物理和润湿性能，这些复合材料是通过真空辅助树脂传递成型制造的。技术。还测定了混合复合材料的储能模量、损耗模量和 tan δ值以评估 DMTA 性能。结果表明，黄麻/聚酯树脂的储能模量是优于黄麻木材/聚酯混合和木材/聚酯至玻璃化转变温度（的Ť _克）。然而，对于高于T _{g 的}温度范围，混合复合材料的刚度相对增加。损耗模量和 tan δ 峰的T _g值支持这种杂交效应。机械性能测试表明，与黄麻-木材/聚酯混合和木材/聚酯试样相比，黄麻/聚酯试样的拉伸强度显着增加。物理性能测试结果表明，与黄麻/聚酯和黄麻-木材/聚酯复合材料相比，木材/聚酯试样的厚度膨胀、吸水率和水分含量最低。从由木材/聚酯制成的复合材料中获得最高接触角。可以得出结论，具有增强性能的复合材料可用作各种领域的新型绿色复合材料。
