Effect of Surface Treatment on Interfacial Strength between Bamboo Fiber and PP Resin

Abstract

The interfacial shear strength (IFSS) between a bamboo fiber bundle and maleic anhydride polypropylene (MAPP) was examined for various kinds of surface treatments in conjunction with ultrasonic washing. Bamboo fiber bundles were extracted from Chinese bamboo by either mechanical scratching or steam explosion. The effect of fiber bundle diameter on IFSS was measured by using the micro-droplet test. The test results showed that higher IFSS was observed for bundles having smaller diameter. Isocyanate silane treatment improved IFSS in the case of raw bamboo fibers while it was less effective to improve IFSS for steam exploded fibers. The highest tensile strength of bamboo fiber reinforced polypropylene was obtained when steam exploded bamboo fibers were used as the reinforcement.

A new amino silane coupling agent for old corrugated container fibers/high density polyethylene composites

“…In comparison to non‐treated composite, the composites with 2 wt% silane coupling agent may increase both tensile strength and tensile modulus as high as 30% and 27%, respectively. This is contrary to other studies where silane coupling agent has a slight effect on the mechanical properties .…”

“…Most researchers have reported a similar increase in tensile properties with increasing silane coupling agent [10,31]. Adding silane coupling agent has improved fibers dispersal in polymer matrix surface, improvement in adhesion between OCC fibers and polymer matrix and consequently more restriction in polymer chain movement [24]. Proper adhesion between fibers and polymer can promote stress transfer from the matrix to cellulose fibers and result in significant increase in mechanical properties of the samples prepared by coupling agent [32].…”

Effect of Mimosa Grafting on Anatomy, Chemical Composition and Tensile Properties of Bamboo Fiber

“…Chen et al used cardanol as grafting agent in preparation for better performance of composite. In their experiment isocyanate silane and amino silane were used to modify the surface of bamboo fiber [15,16]. In present research mimosa was used for grafting the surface of bamboo fiber.…”

“…Li worked on Phyllostachys pubescens bamboo and found 5.14% hot water solubility, 22.11% lignin, 70.84% holocellulose, 47.30% α-cellulose, 1.94% ash [26]. Ghoshal et al worked on bamboo fiber and found 60% cellulose and 32% lignin [16]. During present chemical analysis, alpha cellulose was found to be 50.23±.18% indicating that homopolysacsride consist of β-D-glucopyranose linked together by β,1-4-linkage.…”

Acetylation of Chinese bamboo flour and thermoplasticity

“…Greenhouse effect has been becoming one of the most serious environmental concerns (Tung and Yamamoto 2004). Polymer composites based on fossil oil cause a heavy burden from the viewpoint of sustained development.…”
