The invention is shown to achieve uniform deposition of particulate types on carbon fiber fabric. This approach enhances the fabrication of vacuum assisted resin transfer molding (VARTM) laminates with improved mechanical properties.The method enables rapid and uniform deposition of functionalized graphene platelets onto carbon fiber fabric. It was observed that uniform deposition of particulates on the fabric facilitates effective resin impregnation during composite manufacturing and increases the interphase thickness of fibers, thereby enhancing the mechanical properties of the composites.
- Carbon fiber fabrics obtained has improved tensile and flexural properties
- Carbon fiber fabric further used in composite fabrication to improve the interfacial properties
- Carboxyl functionalized graphene (G-COOH) platelets dispersed in a solution, prepared by adding Mg (NO3)2 in DI water
- Individually deposited particles with no agglomerations
- Achieved uniform deposition of G-COOH particles on carbon fibers fabric
- Helps to reduce the time of deposition, and the weight of G-COOH platelets
Before deposition, pristine carbon fiber (CF) fabric was cut into 150mm × 150mm pieces, and copper tape was wrapped around all four edges. A dispersion solution was then prepared. The CF fabric was immersed into the suspension in the middle slot of the container and connected to the cathode (-) working electrode. Two stainless steel plates, each measuring 150mm × 150mm with a thickness of 0.6-1.4mm, were placed on either side of the working electrode and connected to the anode (+) counter electrode. The gap distance between the working electrode and the counter electrodes was set between 0.6-1.4cm. The optimized process parameters for achieving uniform particulate deposition involved applying a constant direct current voltage of 9-21V and a deposition time of 12-28 minutes.
The invention has a proof of system and is ready for deployment. Carbon fiber fabrics underwent sonication-assisted EPD with uniformity of deposition and were compared with pristine carbon fiber specimen. They showed improved tensile and flexural properties over the specimen.
