Abstract

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.
