A comprehensive review on fiber-reinforced polymer composites: Raw materials to applications, recycling, and waste management

Aluminum/epoxy resin interpenetrating phase composites (IPCs) were directly strengthened by adding glass fiber of varying content (80 wt.%, 100 wt.%, 120 wt.% and 140 wt.%) inside the epoxy resin. The macro and micro structures of IPCs were intact, and the interface between aluminum and epoxy resin was well combined. As the content of glass fiber increased, the compressive strength of epoxy resin increased, but the failure was advanced, while IPCs displayed the opposite trend. IPCs exhibited three compression deformation modes, namely plastic deformation of aluminum, resin fracture and interface debonding. The digital image correlation and infrared thermal imager were used to characterize the apparent principal strain distribution and temperature distribution of IPCs to verify the deformation modes. The surface temperature damage evolution of IPCs included the rapid temperature rise stage, steady temperature stage and slight temperature drop stage, respectively, mainly corresponded to the linear elastic stage, plateau stage and densification stage in the stress-strain curves.

Due to their outstanding properties, bamboo-based fiber composites are gaining significant traction in the fields of construction and decoration. Among the crucial process steps in their production, hot pressing stands out as a pivotal one. Temperature, being a key parameter in hot pressing, and its stability of control exert a profound impact on the finished mechanical properties and associated indices of bamboo-based fiber composites. In this investigation, we introduce an active disturbance rejection control (ADRC) methodology specifically tailored for the hot-pressing temperature of bamboo-based fiber composites. A mathematical model encompassing the motor, steam regulating valve, and, ultimately, the hot-pressing temperature is formulated, with the transfer functions at each level being precisely determined through parameter identification techniques. The simulation outcomes reveal that in the absence of signal interference, sinusoidal signal interference, or random signal interference, the ADRC method outperforms the traditional PID algorithm in the realm of hot-pressing temperature control for bamboo-based fiber composites. This approach effectively reduces the temperature fluctuations of the PID algorithm, thereby averting issues such as premature curing or board bursting. In summary, this study holds significant implications for enhancing the mechanical properties of bamboo-based fiber composites.
