Abstract
Polymer-based composite materials have been widely developed as alternatives to conventional materials due to their advantages such as low density, corrosion resistance, and tailorable mechanical properties. This study aims to analyze the effect of hot press temperature variations on the mechanical and physical properties of polypropylene (PP) composites reinforced with cotton fabric. The composites were manufactured using the hot press method at temperatures of 160°C, 170°C, and 180°C, and compared with pure polypropylene specimens. Mechanical properties were evaluated through tensile testing to determine tensile strength, strain, and elastic modulus, while physical properties included density, water absorption, and thickness swelling. The results indicate that hot press temperature significantly influences the composite characteristics. The highest strain value of 3.18% was obtained at 170°C, while the optimum tensile strength of 4.18 N/mm² was achieved at 160°C. Increasing the temperature to 180°C tended to reduce certain mechanical properties, likely due to thermal degradation of the matrix and reinforcement. Overall, proper control of hot press temperature plays a crucial role in enhancing the interfacial bonding between polypropylene matrix and cotton fiber, resulting in composites with improved mechanical and physical performance.
