Continuous fiber reinforced thermoplastic composite pultrusion with in situ polymerizable methyl methacrylate: A review

Abstract

Compared to thermosetting resins, thermoplastic polymers offer many advantages as fiber reinforced composite matrices, such as excellent toughness, superior corrosion resistance, weldability, and recyclable, etc. However, the processibility of thermoplastic composites is commonly considered as a challenge because of the high viscosity of polymer melts (e.g., polypropylene, polyetheretherketone, etc.), which remarkably hinders their applications. Using low viscosity and in situ polymerizable thermoplastic resins to manufacture continuous fiber reinforced thermoplastic composites have been deemed as a cost-effective emerging approach to surpass the processibility challenges. Therefore, this paper presents an overview of advancement in the engineering, high-performance and room-temperature-processible liquid methyl methacrylate (MMA) resins and their composites up to date. First, the polymerization behavior and kinetic modeling of the MMA resins are reviewed, and the effects of initiators on the polymerization are summarized. In the second part, the pultrusion process and modeling including impregnation, temperature distribution and pulling force are discussed. Next, the mechanical properties and durability of the carbon fiber-, glass fiber-reinforced MMA-matrix composites are presented. Finally, the challenges of the preparation and application of the MMA-matrix composites are identified.

Enhanced fracture toughness and tensile strength of 3D printed recycled ABS composites reinforced with continuous metallic fiber for load-bearing application

“…As a result, the production method of CFRTPC was believed to have a wide range of applications across various industrial sectors, including automotive, aviation and medicine. The common production of CFRTPC includes pultrusion (Tian et al , 2023), fiber winding (Boon et al , 2021), hot pressing (van de Werken et al , 2021) and automated fiber placement (Air et al , 2023). These methods typically require substantial investments for procuring expensive equipment and molds, thereby making it a challenging endeavor for part fabrication.…”

An acrylic resin system for in‐situ pultrusion: Curing performances and rheology

“…6 Acrylic resins with the low viscosities, can be polymerized at room temperature with compatible initiator systems and even supposed to be suitable for producing large composites with continuous fiber reinforcement. 25,26 The idea has aroused the generation of Elium ® , a series of thermoplastic acrylic resins produced by ARKEMA, which was employed in producing FRPs via in situ polymerization. The previous researches on the physical properties of MMA matrices and their composites are illustrated in Tables 1 and 2, respectively.…”

Durability of glass fiber reinforced thermoplastic polypropylene composite bars under the coupling effect of seawater and sea sand concrete environment and sustained bending

“…Therefore, the possible use of fiber reinforced thermoplastic polymer (FRTP) composites in civil structures is under investigation because FRTP composites have advantages like better recyclable potential and better abrasion and impact resistance. [15][16][17][18] Besides, FRTP composites can be reshaped in construction sites because of their linear molecular structures, 19 which is quite useful for producing FRTP stirrups and bendable FRTP reinforcements to carry shear force when reinforcing concrete. Glass fiber reinforced polypropylene (GFPP) bars have a high potential to be used in the SWSC environment because of the low cost of glass fibers and the excellent chemicals resistance of polypropylene (PP).…”
