ABSTRACT

In response to the problem of interlayer performance degradation caused by insufficient fiber/resin interface bonding and fiber relaxation during the molding process of Glass Fiber Reinforced Polymer (GFRP) composites, a preparation strategy of "nanoscale interface modification molding tension synergy" is proposed. Firstly, a chemical grafting method promoted by silane coupling and coupling agents was used to stably graft aminated carbon nanotubes (CNTs) onto the surface of glass fibers to enhance interfacial bonding; Secondly, design and manufacture a hot press mold that integrates a dual-mode tensioning mechanism (double-sided synchronous displacement tensioning and center guided anti deviation) and a uniform heating scheme to achieve stable tensioning and uniform temperature field control of short fibers during the curing process. Prepare GFRP laminates using the same raw materials and curing system, and conduct short beam shear tests in accordance with JC/T 773-2010. The results showed that the interlaminar shear strength (ILSS) of CNT modified laminates increased from (53.46 ± 2.36) MPa to (68.89 ± 2.90) MPa, an increase of 28.9%. Research has shown that the multi-level interface structure formed by CNT grafting can enhance mechanical interlocking and chemical bonding, while tension forming and uniform heating provide stable process guarantees for interface infiltration and curing. This study provides an engineering implementation path for the controllable molding and interface enhancement of GFRP components for automotive lightweighting.
