COMPOSITE BULLET-RESISTANT UNIFORM MATERIAL AND METHOD OF ITS MANUFACTURE Russian patent published in 2018 - IPC F41H1/02 F41H5/04 B32B27/12 

FIELD: weapons and ammunition.

SUBSTANCE: material is formed as an intersecting composition of N double-layered structured unit elements, where 1≤N≤8, an organic thin film attached to both sides thereof; wherein the intersection angle of each adjacent layer is 45-90°. The first layer is a fibrous bullet-resistant tape with a unidirectional fibre orientation coated with the first polymeric adhesive. The second layer is a fibrous bullet-resistant tape with a unidirectional fibre orientation coated with the second polymeric adhesive. The tension modulus of the first polymeric adhesive is less than 6 MPa, and the tension modulus of the second polymeric adhesive is greater than 6 MPa. The loss modulus of the first polymeric adhesive and the second polymeric adhesive under the same conditions is the same as the loss modulus of the bullet-resistant fibre.

EFFECT: invention ensures creation of a soft composite bullet-resistant uniform material that has acceptable hardness and increased bullet resistance.
