Abstract
Composite materials have gained widespread application in modern industry due to their superior properties. This study focuses on the mechanical performance and applications of novel composite materials, aiming to explore their behavior under different environmental conditions and potential application fields. By screening and combining various matrix materials and reinforcements, advanced fabrication techniques including hot pressing and resin transfer molding were employed to prepare composite samples with specific structures. Mechanical property tests such as tensile, compressive, and flexural testing were conducted using universal testing machines and dynamic mechanical analyzers, complemented by microscopic structural characterization via scanning electron microscopy. The results indicate that this novel composite material exhibits high strength, high modulus, and excellent toughness, maintaining stable mechanical properties even under extreme temperature conditions, demonstrating significant advantages over traditional materials. Innovatively introducing nanoscale reinforcements effectively enhanced interfacial bonding strength, addressing the issue of interfacial weakening prevalent in conventional composites. Furthermore, optimizing fabrication process parameters enabled precise control of material properties. This research not only provides new insights into composite material design but also lays a theoretical foundation for its application in high-end fields such as aerospace and automotive manufacturing, possessing substantial academic value and broad application prospects.
