Fabrication of lightweight and high-strength carbon fiber-reinforced poly(ethylene-2,6-naphthalene) solid and foam composites

Abstract

Poly(ethylene-2,6-naphthalene) (PEN) is one of the most important engineering polymers with high performance. However, the effects and foaming behavior of carbon fiber (CF)-reinforced PEN (CFRPEN) remain to be explored. In this study, PEN was used as the matrix for CF-reinforced composites, and its foaming behavior and mechanical properties were investigated. High mechanical properties can be evaluated through comparison with other similar CF-reinforced thermoplastic composites. A fabrication method to generate lightweight and high-strength CFRPEN composites is hence proposed.

“…Figure 1 shows the experimental schematic diagram of the preparation of the FRPC pellets, which included the three types of FRPC pellets, that is, SGFPC, LCFPC, and SGFLCFPC. The general preparation process of SGFLCFPC can be described as follows, which can also refer to other composite fabrication 38 . PC resin and SGF were added proportionally to the hopper of a twin‐screw extruder (SHJ‐35, Lianjiang, Zhangjiagang, China).…”

The PC resin was melted in the barrel and mixed with the SGF to form a uniform melt.…”
