| description | Fiber reinforced (FRP) composite materials have high strength-to-weight ratios and excellent corrosion resistance. Cost reduction manufacturing through methods like Vacuum Assisted Resin Transfer Molding (VARTM) is impressive. This paper deals with composite materials reinforcement of railway tank cars via VARTM to enhance safety, improve fuel efficiency, and reduce adverse environmental impact during derailments aligning with industry goals for safer, sustainable solutions in relation to new railway tank car safety standards. This study investigates different performance aspects of various fiber/fabric configurations (glass, aramid) used as reinforcement with vinyl ester or epoxy. Additionally, core materials like polyurethane and polypropylene have been researched to enhance energy absorption. Effects of through-thickness stitching on mechanical integrity are evaluated for improved puncture resistance. Testing revealed that Kevlar fibers increased energy absorption by increasing strain to failure. Epoxy resin lowered maximum tensile strength by 22% compared to vinyl ester and increased the total energy absorption by 8%. Through-thickness stitching (z-direction) increased tensile strength by 13% and improved interlaminar shear strength. |
