Abstract

The importance of creating and using green items made of natural fibers and natural fiber composites rather than conventional goods has increased as awareness of sustainability has grown. Stipa Tenacissima L., often known as alfa grass, is a tussock grass that is endemic to North Africa and southern Europe. This study investigated the effects of atmospheric aging through three months on the mechanical properties of polyester /alfa fibers reinforced with different proportions of natural fibers (10, 20, and 30 wt%). For this purpose, three-point bending tests were performed on pure polyester and polyester /alfa fiber composites specimens. Based on the mechanical tests of the composite specimens, a finite element model of flexural testing was developed to analyze the mechanical behavior of the Alfa/polyester composite. The test results showed that the alfa fibers have been demonstrated to have potential for natural fiber composites under a variety of environmental circumstances. The alfa coarse fibers with 30 wt % were capable to enhance the mechanical properties of the polyester/alfa composite.
