Effect of Sugar Palm Fiber Surface on Interfacial Bonding with Natural Sago Matrix

Abstract

Palm fibers were immersed in sea water for 1, 2, 3, and 4 weeks prior to application as reinforcement of green biocomposite. Instead of common resin matrix, natural sago starch was applied as the matrix compound. The immersion treatments had significantly affected fibers surface morphology and interfacial bonds of fiber and the matrix as observed through Scanning Electron Microscopy (SEM). The quality of interfacial bonds became higher by additional duration of the sea water immersion. The best interlocking surfaces of fibers and matrix appeared in the composite with 4-week immersed fibers, indicated by disappearance of gaps between fiber and matrix. The morphology of fibers surface interlocking process was clearly seen during the duration of immersion.

Effect of liquid smoke on surface morphology and tensile strength of Sago Fiber

“…In recent years, natural fibers have been widely studied by experts as industrial materials such as mengkuang fibers, palm fibers, akaa (corypha) fibers, king pineapple leaf fibers, coconut fibers, carica papaya fibers, albizia amara fibers, and juncus effuses L fibers [1][2][3][4][5][6][7][8][9]. This study discusses the treatment of Sago fiber (SF) using acetic acid in liquid smoke from coconut shell which is more eco-friendly than other alkali treatment.…”

“…Treatment with NaOH removed hemicelluloses and lignin in natural fibers and decreased the moisture content [11]. Seawater immersion of straw fibers also degrades lignin layer while providing harder surfaces [5,12,14]. Heating treatment of akaa (corypha) midrib fiber with turmeric solution increased the level of cellulose compound and reduced lignin content, increasing fiber's strength [6].…”

“…For example, akaa (corypha) midrid with turmeric solution treatment greatly affect the ability of C=C and O=H absorption [6],the lignin and hemicelluloses content in the KPLF (King pineapple leaf fibers) were reduced after fumigation [4]. In an XRD test of sugar palm fiber, a consistent emergence phenomenon of crystal peak diffraction occurred as reaction to seawater [5]. Chemical treatment leads to crystallization on the surface of the fiber, where alkali treatment improves the crystallinity and exhibits new chemical bond formation in the sponge-gourd fiber (SGF) [18].…”

Determinação Da Tenacidade Ao Impacto Izod De Compositos De Matriz Poliéster Reforçados Com Fibras De Bucha

“…Diante do constante avanço da sociedade, exige-se cada vez mais o uso de materiais naturais biodegradáveis, dando maior ênfase à consciência ambiental, visto que, materiais convencionaisutilizam fontes de energia não renováveis e causam impactos a meio ambiente, como poluição a longo prazo e mudanças climáticas. Diante do exposto, a utilização de materiais compósitos com incorporação de fibras vegetais mostra-se uma solução viável para o planeta [1][2].…”

“…O Brasil tem grande potencial em fibras naturais, estando situado em uma região tropical com vastas florestas e clima propício para as plantas [1,5]. A incorporação de fibras naturais em compósitos tem sido vastamente investigada por pesquisadores uma vez que, materiais reforçados com estas fibras mostram ter maiores limites de resistência, modulo de elasticidade, baixo custo,biodegradabilidade,boas propriedades mecânicas e seu desempenho pode ser igual ou superior, quando comparadas às fibras convencionais sintéticas, como vidro, aramida e carbono [4,6].…”
