The invention provides a high-strength fabric and a manufacturing method thereof. The manufacturing method includes: connecting at least one group of single yarns according to a certain law to manufacture a fabric body, wherein the high-strength fabric includes at least the fabric body, and each single yarn is manufactured by converging or converging and twisting an ultra-high molecular weight polyethylene thin film or strip. The high-strength fabric has the advantages of good structural integrity, simple manufacturing process, high production efficiency, high strength, high strength utilization ratio, light weight, no pollution and good bulletproof performance.
