Abstract: A bulletproof panel includes: (i) a ceramic plate A; (ii) at least one phenol resin impregnated aramid fabric laminate C having phenol resin impregnated aramid fabrics C1, C2 and C3 which are laminated thereon; and (iii) an epoxy resin impregnated fabric B disposed between the ceramic plate A and the phenol resin impregnated aramid fabric laminate C, and impregnated with an epoxy resin. The phenol resin impregnated aramid fabrics C1, C2 and C3 may be aramid fabrics impregnated with a phenol resin, and aramid fabrics impregnated with a phenol/polyvinyl butyral mixture resin. The ceramic plate A and the phenol resin impregnated aramid fabric laminate C are not delaminated from each other even under a high-temperature environment, and thereby greatly enhancing the bulletproof performance.

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.
