A stab and ballistic resistant material and method of preparing the same, comprising a stab-resistant layer and a ballistic resistant layer, wherein the stab-resistant layer comprises at least one layer, wherein each layer is constituted of two structural units, each of which is formed from perpendicularly combined high strength and high module unidirectional fiber prepreg strips, adjacent structural units are rotated 45°, and the stab-resistant layer has membranes adhered to both sides; the ballistic resistant layer comprises at least one layer, wherein each layer is constituted of two structural units, each of which is formed from perpendicularly combined unidirectional fiber prepreg strips, adjacent structural units are rotated 90°, and the ballistic resistant layer has membranes adhered to both sides. The stab and ballistic resistant material of the invention makes stab and ballistic resistant vests lighter, more efficient in protection, and easy to produce.
