PREPARATION PROCEDURE FOR THE SAME
FIELD OF THE INVENTION
The present invention relates to the field of materials, and particularly relates to a ballistic resistance composite unit material and the process for the preparation thereof.
BACKGROUND OF THE INVENTION
A ballistic-resistant material is a high-modulus, high-resistance fiber-based compound and is generally applied in individual protection, such as body armor. Ballistic resistance materials are mainly classified as soft and hard ballistic resistance materials, which have different ballistic resistance mechanisms. The hard ballistic resistance material mainly uses its hardness to alter the shape of a bullet or fragment, which reduces its kinetic energy and produces a ballistic resistance effect, while the soft ballistic resistance material mainly uses the deformation of the soft ballistic resistance material to produce a damping effect, to absorb the kinetic energy of a bullet or shot fragment on it, thus achieving the purpose of ballistic resistance.
The ballistic resistant material may have a composite structure of high strength high modulus unidirectional fibers such as high strength fibers and high modulus polyethylene fibers or aramid fibers. Said ballistic resistance material has a ballistic resistance performance to a certain extent; however, since the resin adhesive used in each layer of the ballistic resistance material is a unique resin system, the ballistic resistance material is too soft, causing the material to be easily penetrated when subjected to the advancement of a steel core bullet; or it is too hard, which makes the user feel uncomfortable.

US7378147 has disclosed the use of a dynamic mechanical analysis (DMA) test procedure to test the modulus of loss of polyethylene threads. Dynamic mechanical analysis is a technology of applying a dynamic stress or deformation to a sample and the analysis of the response to obtain mechanical performance such as a storage modulus (E '), loss modulus (E' ') and damping ( as δ) as a function of temperature and / or frequency.
The storage module is a capacity by which a material is capable of storing the energy applied to it for later use or for use during rebound deformation. The loss modulus is a capacity by which a material is able to dissipate the energy applied to it, for example, the energy lost due to a failure to return to its original shape after the plasticine is stretched. tan δ is a ratio between the storage modulus and the loss modulus.
For the test on the loss modulus of patent US7378147, a maximum value of the loss modulus was obtained at a frequency of 10 or 100 radians / second, within a temperature range of -150 ° C to 125 <sup>0</sup> C and under a deformation value of 0.025 ± 0.005%.
Although the loss modulus of a ballistic resistance fiber is associated with ballistic resistance performance, there has been no report on the correlation between its loss modulus and the loss modulus of a resin adhesive.

The acrylic resin adhesive was replaced with a polyurethane resin adhesive with a tensile modulus of 8 MPa, and its loss modulus was adjusted by adding a crosslinking agent, so that it is the same as the loss modulus of the ballistic resistance fiber at 30 -40 ° C under the same conditions. Then, another unidirectional fiber tape was prepared, with an area density of 35 g / m<sup>2</sup> and a fiber content of 75%.
The unidirectional fiber tape comprising the acrylic resin adhesive was used as a continuous sheet, and the unidirectional fiber tape comprising the polyurethane resin adhesive was cut into sections with the
