Manufacturing of a natural fiber/glass fiber hybrid reinforced polymer composite (PxGyEz) for high flexural strength: an optimization approach

Abstract

Due to their low density, natural fibers have increasingly found application in the development of systems such as wind turbine blades, airplane wing spar where flexural strength is a strong criterion for material selection. Although different researchers have studied the mechanical properties of such natural fiber composites, none has focused on the optimization of the flexural strength of pineapple leaf fiber (PALF)/glass fiber (GF) reinforced epoxy hybrid composite. This study applied the Taguchi and general regression analysis method in the optimization and modeling of the flexural strength of the P x G y E z composite. Flexural strength of 144.5 MPa at an optimum development parameter of PALF at 20% volume content, GF at 20% volume content, and fiber length of 25 mm. Analysis of variance and regression analysis was also employed to describe and model the flexural behavior of the developed composite. The PALF fiber showed to have a higher contribution to the flexural strength of the material. The equation developed to model the flexural behavior of the material showed a good correlation between the simulated value and the experimental values of the flexural strength at different combinations of manufacturing parameters.

A Study of the Flexural Properties of PA12/Clay Nanocomposites

“…The mechanical properties of composites have been studied extensively, mostly through experiments but also through additional computational methods [ 10 , 11 ]. Modelling and optimization techniques used allow researchers to find the best combination of constituent materials and processing parameters for obtaining optimal properties of the resulting composites [ 12 , 13 , 14 ]. Several statistic-based techniques are used for the optimization of processing variables; one of these is the response surface method (RSM).…”
