摘要

Prevalently, the light has shed on the green composite from the view point of environmental protection. Jute fibers are natural fiber superior on light weight, low cost and environmental friendly corresponding to the green composite materials. Meticulously, fibers of polylactic acid (PLA) thermoplastic biopolymer were micro braided around jute spun yarns and paralleled configuration with jute. The pultrusion experiments were done with jute/PLA yarns and combined with glass fiber yarns to fabricate the tubular composite. Impregnation quality was evaluated by microscope observation of the pultruded cross-sections. The flexural mechanical properties of the beams were measured. The jute/PLA tubular pultrude composite using the parallel configuration of yarn showed the highest bending strength 28.3 MPa and modulus 15.4 GPa with the filling ratio 130% and volume fraction 52%.
