Effect of Long Basalt Fiber on Flexural/Tensile/Impact Strength Behavior of Low-Density Polyethylene Composite

The main motto of the present research comprises investigating flexural/tensile/impact strength properties of low-density polyethylene (LDPE) embedded with long basalt fiber (BF) through a hand layup technique associated with compressive force, and their values are related to LDPE lamina without long basalt fiber. With specific benefits, the LDPE and basalt fiber are used as polymer matrix and reinforcement. The LDPE polymer matrix is embedded with a 4–12 weight percentage of long basalt fiber. The fabricated LDPE/BF composite’s flexural/tensile/impact performance is evaluated by ASTM standards like S790, D3039, and D7565, respectively. Here, the flexural/tensile/impact strength of the composite is noted by an uptrend in the inclusions of long basalt fiber as 0, 4, 8, and 12 wt% respectively, and the highest flexural/tensile/impact strength of LDPE with 12 wt% of BF is recorded by 22.4 ± 1 MPa, 10.8 ± 0.4 MPa, and 37 ± 1 J/cm2, respectively. LDPE’s maximum flexural, tensile, and impact strength behavior with 12 wt% of long basalt fiber is suggested for automobile roof frame applications.
