Carbon fiber reinforced plastic (CFRP) is a lightweight material with excellent mechanical properties that is being used in high-value-added industries such as automotive and aviation. However, as CFRP has gained popularity as a lightweight material that can replace steel, it has also led to a surge in waste emissions, which has resulted in high social costs. Therefore, researchers proposed to remanufacture CFRP by applying recycled carbon fibers derived from CFRP waste instead of virgin carbon fibers to CFRP. In particular, among the various rCFRP manufacturing processes, the FDM(Fused Deposition Modeling) process has been attracting attention for manufacturing rCFRP, but the mechanical strength is reduced due to the low interfacial adhesion of rCF(recycled Carbon Fiber) and the inherent low interlayer bonding of the FDM process. Therefore, this study applied Isostatic Pressure method to improve the mechanical strength of rCFRP and analyzed the mechanical behavior according to pressure and time. rCFRP pellets were produced by twin screw process using rCF/ABS, and composite filaments were produced by single extrude process. After the rCFRP specimens were produced through 3D printing, post-processing was performed according to pressure and time. To evaluate the quality of the post-treated rCFRP, morphology analysis was performed using SEM(Scanning Electron Microscope), followed by mechanical strength analysis using a UTM(Universal Testing Machine). The results of this study can be used as a reference for improving the strength of rCFRP materials.
