摘要
In the industrial sector, ultra-high molecular weight polyethylene (UHMWPE) fibers are often recognized as superlative reinforcement owing to their unmatchable characteristics like impressive toughness, exceptional weight-to-strength ratio, low density, excellent wear, and chemical resistance. The remarkable features of UHMWPE fiber/polymer composites have gained substantial attention, rendering them ideal for advanced engineering materials. Despite this, advancements in developing high-performance UHMWPE fiber polymer composites have been constrained by the fiber's smooth and chemically inert surface, resulting in a weak interface between UHMWPE and the polymer matrix. Numerous techniques have emerged to enhance the surface of UHMWPE fibers, aiming to bolster the fiber-polymer matrix interface. These modifications amplify surface chemical activity and roughness, thus achieving robust mechanical interlocking and chemical bonding. This review paper aims to elucidate how the physical and chemical surface modifications of UHMWPE fibers fortify the interface with polymer matrices. Researchers can leverage the presented techniques to design advanced composites with improved performance and durability. This article provides a concise overview of current developments in various surface modification techniques for UHMWPE fibers and their role as polymer reinforcements. Last, ongoing challenges and potential research directions in UHMWPE reinforced FRPCs are also discussed.
