Interfacial properties of windmill palm (Trachycarpus fortunei) fiber reinforced laminated veneer lumber (LVL) composites under high voltage electrostatic field (HVEF)

The acid/alkali pretreatment of windmill palm fiber (WPF) and the application high voltage electrostatic force (HVEF) technology were used to prepare WPF-reinforced laminated veneer lumber (LVL). effects on surface morphology, chemical composition, crystallinity mechanical properties WPF investigated. Moreover, intensity HVEF composition wettability analyzed. Based experiment reinforced LVL composites, mechanism for reinforcement composite was systematically clarified. results showed alkali treatment efficiently removed silica particles cuticles produced with relatively Young’s modulus tensile strength (increased by 167.07% 26.52%, respectively). After treatment, increase surface-active groups (- OH - CHO) led oxidation degree water contact angle WPF. Under synergistic effect HVEF, interfacial between adhesive improved. This study that not only broaden scope WPF, but also provide insights into engineering production.
