Special Issue Information

Dear Colleagues,

Fiber-reinforced polymer (FRP) composites have attracted significant attention due to their outstanding mechanical performance, lightweight nature, corrosion resistance, and adaptability for diverse applications ranging from aerospace and automotive to energy and infrastructure systems. The continuous evolution of stiff fiber and tough polymer matrices, advanced fabric architectures, and nano-/micro-modification strategies have expanded their potential for structural and functional integration in next-generation engineering systems.

This Special Issue, titled “Fiber Reinforced Polymer Composites: Preparation, Applications and Prospects”, aims to provide a comprehensive platform for disseminating recent advances in the design, processing, characterization, and application of FRP composites. Topics of interest include, but are not limited to, the following: innovative fabrication and surface modification techniques; interfacial engineering and toughening mechanisms; multifunctional properties such as thermal management, flame retardancy, or electrical conductivity; computational modeling and simulation of composite behavior; and industrial applications in space/aerospace, industrial applications, ballistic protection, sustainable mobility, renewable energy, and construction.

We particularly welcome contributions that highlight broad emerging research trends, novel experimental or theoretical approaches, and practical case studies that demonstrate the future prospects of FRP composites in addressing global technological challenges. Both original research articles and critical reviews are encouraged.

We look forward to your valuable contributions to this Special Issue and to advancing the field together.

Thermoplastic hybrid composites reinforced with flax and glass fibers offer a sustainable, high-performance alternative for structural applications by balancing stiffness and energy absorption. This study investigated the impact of low-pressure plasma treatment on the thermal, mechanical, and microstructural properties of two polypropylene-based laminate configurations, PFGFP (polypropylene–flax–glass–flax–polypropylene) and PFGGFP (polypropylene–flax–glass–glass–flax–polypropylene), to optimize fiber–matrix interfacial adhesion. Materials were characterized using differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), tensile testing, and scanning electron microscopy (SEM). The plasma treatment significantly enhanced the lignocellulosic fibers’ surface energy, reducing the flax contact angle from 93.5° to 56.1°. DSC analysis revealed a matrix crystallinity of 35.41%, while TGA confirmed flax thermal stability up to 250 °C. The PFGFP configuration exhibited superior mechanical performance (Tensile strength = 61.69 MPa; Young’s modulus = 518.62 MPa), attributed to its symmetric architecture and efficient fiber impregnation. Conversely, PFGGFP showed reduced strength and microstructural voids due to incomplete wetting in dense reinforcement regions. These findings conclude that the synergy between plasma surface modification and optimized laminate architecture is critical for the design of high-performance sustainable composites, providing an objective basis for improving interfacial compatibility in hybrid systems.
