Layered self‐resistance electric heating to cure thick carbon fiber reinforced epoxy laminates

Abstract: Curing of thick carbon fiber reinforced thermosetting composite laminates has been a major challenge due to the undesired through-thickness temperature gradient. In this paper, a novel layered self-resistance electric heating (L-SRE) method to cure thick laminates was proposed. The thick laminate was divided into multiple independent sub-layers, and the temperature of each sub-layer was controlled individually. The experiment's results revealed that L-SRE was able to achieve highly homogeneous temperature dist… Show more

“…Nevertheless, due to high melting point and viscosity of thermoplastic resin, and the heating methods of external thermal source, the traditional molding methods mentioned above are excessively high energy consumption, low efficiency and even poor impregnation degree [11]. Self-resistance electric (SRE) heating [11][12][13], which conducts current directly to the carbon fiber (CF) and heats the surrounding resin by the joule heat generated, provides an effective way to fabricate cCFRTs.…”

“…Another promising method for energy-efficient and cost-effective curing of FRPCs is direct conductive heating of composite laminates via a resistive heater. , In contrast to conventional autoclave- or oven-based curing approaches, where a large fraction of the consumed energy is used to heat the gas inside an autoclave or oven to transfer the heat to the composite laminate via convective heat transfer, resistive heating allows for direct heating of the composite layup through conduction, resulting in substantial energy saving . Metal meshes, carbon fibers, and various conductive nanomaterials have been used as resistive elements for conductive heating and curing of composites. , Nanostructured films and papers of carbon nanomaterials (e.g., buckypaper, graphene paper, and laser-induced graphene) are particularly promising for Joule heating of composites due to their excellent Joule heating properties, deformability, ease of integration into composite layups, and low thermal mass and density. ,, Another advantage of using nanostructured heaters is that they can be integrated into composite laminates and impart new functions to the host composite such as self-heating, deicing, lightning strike protection, and self-sensing of damage and strain …”

“…[29] To be specific, Fukuda et al [30] firstly introduced SRE heating technology to the curing process of carbon fiber reinforced epoxy resin and evaluated mechanical properties of the laminate. Liu et al [31,32] optimized SRE heating process parameters to improve the mechanical performance of carbon fiber reinforced thermoset composites. Besides, some researchers introduced SRE heating technology to welding process, hot stamping process, injection overmolding process and printed selfheating coating [33] which can be used for deicing and anti-icing devices.…”
