Evaluation of mechanical properties of e-glass and aloe vera fiber reinforced with polyester and epoxy resin matrices

Abstract

Purpose The need for seeking alternate materials with increased performance in the field of composites revived this research, to prepare and evaluate the mechanical properties of e-glass and aloe vera fiber-reinforced with polyester and epoxy resin matrices. Design/methodology/approach The composites are prepared by hand layup method using E-glass and aloe vera fibers with length 5-6 mm. The resin used in the preparation of composites was epoxy and polyester. Fiber-reinforced composites were synthesized at 18:82 fiber–resin weight percentages. Samples prepared were tested to evaluate its mechanical and physical properties, such as tensile strength, flexural strength, impact strength, hardness and scanning electron microscope (SEM). Findings SEM analysis revealed the morphological features. E-glass fiber-reinforced epoxy composite exhibited better mechanical properties than other composite samples. The cross-linking density of monomers of the epoxy resin and addition of the short chopped E-glass fibers enhanced the properties of E-glass epoxy fiber-reinforced composite. Originality/value This research work enlists the properties of e-glass and aloe vera fiber-reinforced with polyester and epoxy resin matrices which has not been attempted so far.

Long Chopped Glass Fiber Reinforced Low-Density Unsaturated Polyester Resin under Different Initiation

“…Chopped glass fiber reinforced composite materials have been a focus of studies in reinforced composite materials of resin matrix. Chopped E-glass fiber and chopped aloe fiber (both in length of 5.0–6.0 mm) were applied in composites of epoxy resin matrix by Jenarthanan et al [ 11 ]. It indicated that more external impact energy absorbed by chopped E-glass fibers and those composite materials presented better mechanical properties.…”
