Abstract:
Introduction: Composite research is adopting innovative materials in the current period
due to their better qualities, such as being lightweight, having excellent mechanical properties, being
relatively inexpensive, having a low coefficient of thermal expansion, etc.
Methods: Composite materials play a crucial part in this challenge, with the fast market growth for
lightweight and high-performance materials. In the present research, different weight percentages of
aramid fiber, glass wool, aluminum, and silicon carbide-reinforced high-density polyethylene hybrid
composite are introduced. The degree of adhesion between the matrix and reinforcement was determined
through microstructural investigation utilizing an optical and scanning electronic microscope.
Results: Mechanical properties (tensile behaviors, flexural behavior, impact strength and hardness
property) of the fabricated composites are investigated. Comparative study of mechanical properties
for different combinations of fabricated composites reveals an increase in elongation at break, flexural
strength, flexural modulus and hardness, while tensile strength and impact strength have decreased
sequentially from 5 to 40 wt.%.
Conclusion: The mechanical properties of HDPE-PPTA-GW-Al-SiC hybrid composites obtained at
40 wt.% PPTA (Poly (p-phenylene terephthalamide)), GW (glass wool), Al, and SiC powder loading
are superior as compared to other hybrid composites.
