The effect of pre-impregnation of short fibers on the dispersion, distribution,and mechanical properties of short carbon fiber/ABS composites

Fused deposition modeling (FDM) is a widely accessible additive manufacturing technique for polymericmaterials. However, the anisotropic microstructure and layer-by-layer nature of FDM can sometimes result inweaker mechanical properties than traditional manufacturing methods. To address this issue, this researchinvestigates the addition of short carbon fibers as reinforcements to strengthen the mechanical properties ofAcrylonitrile Butadiene Styrene (ABS). Short carbon fibers were added in varying amounts (۵, ۱۵, and ۲۵%wt),with pre-impregnation used to improve fiber-matrix interaction and achieve proper fiber dispersion. Tensiletests on the composite filaments revealed that adding ۱۵% short carbon fibers increased the tensile strength byapproximately ۲۵%.
