TAILIEUCHUNG - Properties of Green Composites based on Polypropylene Reinforced by Bamboo Shoot Culm Sheath Fibers

Silane and NaOH were used to treatment bamboo shoot culm sheath fiber. After treatment, the interfacial shear strength of fiber with MAPP increased by 24% and 30% respectively. Alkali treatment has much effect on bamboo shoot culm sheath fiber than silane treatment. Washing NaOH treatment bamboo fiber with acetic acid was improved IFSS of bamboo fiber and polypropylene (PP) and strength of composite PP reinforced by bamboo fiber. | Journal of Chemistry Vol. 45 5A P. 190 -195 2007 PROPERTIES OF GREEN COMPOSITES BASED ON POLyPROPyLENE REINFORCED By BAMBOO SHOOT CULM SHEATH FIBERS Received 16 August 2007 NGUyEN Huy TUNG1 AND TQRU FUjII2 1Polymer Centre Hanoi University of Technology - Vietnam Mechanical Faculty Doshisha University - Japan SUMMARy Silane and NaOH were used to treatment bamboo shoot culm sheath fiber.

I - INTRODUCTION In the world and also in Vietnam the green composite has been paid more and more attentions because of their properties such as cheap available bio-degradable 1 2 . There were many published papers concerned these materials. However these papers were only covered few problems on the natural fibers composite 3 . Bamboo fibers were treated with isocyanate silane or sodium hydroxide to improve interfacial shear strength IFSS with maleic grafted polypropylene MAPP matrix. Microdroplet test was used to investigate IFSS of fibers with MAPP. II - COMPOSITE FABRICATION AND TESTING METHOD Bamboo culm sheath fiber reinforced polypropylene BsFRP was fabricated using hot press method at 190oC and 2 MPa. Interfacial strength was determined by using micro-droplet test under laboratory condition 21 3oC and 60 5 RH. The tensile speed was mm min. IFSS is calculated by the following equation IFSS Fp L1 L2 Here Fp is the maximum load to pull out the fiber from the matrix. L1 is the embedded length of the fiber. L2 is the circumference of the fiber. Fig. 1 Schematic drawing of micro-droplet testing III - RESULTS AND DISCUSSION 1. IFSS of bamboo shoot culm sheath fiber with MAPP 190 In composite material IFSS is an important part on
