Abstract
In this study, effects of surface treatment on tensile and flexural creep properties
of jute fiber reinforced composite were investigated. The reinforcement was
plain woven jute fiber cloth and matrix was polylactic acid (PLA). The jute fiber
cloth and PLA are naturally-derived materials. So, the jute fiber reinforced
composites have a poor interfacial adhesion. Therefore, the silane coupling agent
treatment was used to improve the interfacial adhesion. The alkoxy group of
silane is hydrolyzed and changed by silanol group (Si-OH). And interface
adhesion improvement is expected by covalent bond with the hydroxyl group of
the jute fiber surface. As a result, the interfacial adhesion between jute fiber and
matrix was improved by the silane treatment, and the tensile and flexural creep
strains of composite decreased. The creep compliance of composite was
improved by using silane treated jute fiber except for flexural creep compliance
at high temperature.
Keywords: natural fiber, PLA, silane coupling agent, creep, surface treatment.
1 Introduction
Glass fiber reinforced plastics (GFRP) have high specific strength, stiffness and
corrosion resistance. GFRP has been used for bathtub, marine applications and
so on. GFRP has an environmental problem about waste disposal after use.
However, GFRP generates CO2 at disposal processing. In order to solve this
environmental problem, new composite materials were required instead of
GFRP．Recently, the researches on natural fiber reinforced plastic (NFRP) that
combines the natural fibers and biodegradable polymer were actively conducted
[1–4].
Keywords
natural fiber, PLA, silane coupling agent, creep, surface treatment.
