Abstract:
Disclosed are a high strength fiber composite material, which satisfies bulletproof performance to the level as required in the industry and has greatly improved lightweight properties, a manufacturing method thereof, and a helmet manufactured by using the same. The high strength fiber composite material includes: a high strength fiber material; and a resin film laminated on one surface of the high strength fiber material, wherein an amount of the resin film is 10 to 18 wt. % to a total weight of the high strength fiber material and the resin film, the resin film includes 20 to 70 wt. % of phenolic resin, 20 to 70 wt. % of polyvinyl butyral (PVB) resin, and the polyvinyl butyral (PVB) resin has a molecular weight of 30,000 to 120,000.
