Finite Element Analysis of Flexural Property of Short Flax Fiber Reinforced Polypropylene Composites

Abstract

Recycled general-purpose plastic, polypropylene gained general acceptance because of its excellent properties. At the moment, most of experimental tests of short-natural fibers reinforced polymer composites have been concentrated on macro level, lead to un-matured of fine, micro mechanics research work. In this paper, flexural property of short flax fiber-reinforced polypropylene composites was numerical estimated using a FEM model. It has been observed that initial modulus of the composites increases with the rise in fiber volume fraction, while short fiber orientation distribution has little effect on composites; the stress-strain curves almost have no change.

“…In the works of researchers, new technologies in the field of filter materials, filter structures, raw materials are considered most often [12][13][14][15][16][17][18][19][20]. Also, attention is paid to the very process of filtering the liquid through the filter element [10][11][12][13].…”

“…In this work, it is stated that the screw profile of a twin-screw extruder can be designed to contain elements that cause different levels of degradation in the polymer melt. The paper [18] considers the unique properties of polypropylene and gives attention to the structure of elements from «foamed» polypropylene. It is noted that the initial modulus of composites increases with increasing fiber fraction, while the short fiber orientation distribution has little effect on composites; the stress-strain curves do not practically change.…”
