PHYSICAL AND MECHANICAL PROPERTIES OF PARTS MADE FROM POLYMER COMPOSITE MATERIALS USED IN MECHANICAL ENGINEERING

Abstract

Polymer composite materials have become increasingly important in mechanical engineering applications due to their unique physical and mechanical properties, which offer a combination of high strength, low weight, corrosion resistance, and flexibility. These materials typically consist of a polymer matrix reinforced with various fibers, such as glass, carbon, or aramid, and are engineered to achieve specific performance characteristics. This paper examines the key physical and mechanical properties of polymer composite materials, focusing on aspects such as density, tensile strength, modulus of elasticity, impact resistance, and fatigue behavior.
