The composite had a maximum damping ratio of 0. 2 percent when the curing temperature was 110°C, while the composite cured at 130 u00b0C had a minimum damping ratio of 0. 83 percent, which decreased by 35. 89%. In addition, the composite's damping characteristics were also worse when the curing temperature was higher than that of the composite cured at lower temperatures. The curing temperature was different, the disfiltration ability of resin in the fiber was variable, and the energy dissipation methods in the composite material were different, as shown by the damping properties.

By changing the parameters of electrochemical treatment, carbon fibers with different electrochemical treatment temperatures were obtained, and the effect of electrochemical treatment levels on CF's surface characteristics were investigated by scanning electron microscope, atomic force microscopy, and X-u2010ray photoelectron spectroscopy. The effects of electrochemical treatment on the mechanical properties of CF were investigated by monofilament tensile test and composite laminate 0u00b0 tensile test. The electrochemical treatment had no effect on the mechanical properties of CF, according to a monofilament tensile test and composite laminate 0 u00b0 tensile test. With the improvement of the electrochemical treatment, the CAI of the composite laminates increased first and then stayed relatively unchanged, according to a compression after impact study.

U2010mats are used in this article to produce glass-u2010fiber epoxy reinforced nanocomposites by using electrospun fiberspun as a reinforcing step. Polyacrylonitrile and multiwalled carbon nanotubes solutions have been used to make these fibers. With a fracture strain up to 500 MPa, it has been shown that GFECs made using GF800 glass fiber show an improvement/enhancement of the mechanical properties. Following the ISO 1302's specifications, it has also been reported that GFECs made using GF3M glass fiber showed a decrease in the roughness down to 56%, which corresponds to a roughness decrease from N8 to N7.
