Mechanical Properties of Jute Composite by Spray up Fabrication Method

Abstract In this study, the jute fiber was used to fabricate ecologically friendly composite by spray up molding technique. As the primal investigation , motion analysis of spray up method process was conducted, to obtain fixed quantity of expert's skills default value which is not actualized. Furthermore, dynamic characteristics and dimensional stability measurement was carried out of a specimen, and studies about a relation with an expert's operation was conducted. Thereby, the suitable education and technical tradition to advanced management engineering and inexperienced person are attained. The results suggested that 1) expert's motion data can be feed to jute/carbon spray up robot. And it is able to minimize the errors during fabrication of jute composite panels etc., 2) it is expected that the mechanical property and working efficiency could be improved with the improve of the advanced spray up method and 3) by making the combination of the optimal materials (jute fiber, kind of resin, etc.), high productivity and good elastic modulus are realized. Finally, spray up molding equipment is very flexibility, so it can make various composites easily.
