Abstract:
Provided is a composite ballistic-resistant unit material, formed of an intersecting composite of N two layer structured units, 1≤N≥8, an organic thin film being attached to two sides thereof, the angle of intersection of each adjacent layer being 45°-90°; a first layer is a ballistic-resistant fibre unidirectional tape covered in a first resin adhesive, a second layer is a ballistic-resistant fibre unidirectional tape covered in a second resin adhesive, the tensile modulus of the first resin adhesive being lower than 6 MPa, and the tensile modulus of the second resin adhesive being higher than 6 MPa; the loss modulus of the first resin adhesive and the second resin adhesive, under the same conditions as the test frequency and strain value, at 30-40° C. is the same as the loss modulus of the ballistic-resistant fibre. When the strain sensitive rate of the ballistic-resistant fibre is at 2.4×103 s−1, the dynamic tensile stress is at least 2.4 GPa, and the sound-wave conduction speed is at least 10000 m/s. The composite ballistic-resistant unit material uses two kinds of resin adhesive, respectively coated onto adjacent layers, and the softness and hardness of ballistic-resistant materials produced therewith is appropriate, having excellent ballistic-resistant performance.
