Description

Bulletproof composite material designed according to modulus matching and preparation method thereof
Technical Field
The invention relates to a bulletproof composite material designed according to modulus matching and a preparation method thereof, belonging to the field of bulletproof composite materials.
Background
The bulletproof composite materials used in the prior bulletproof helmets and bulletproof clothes mainly comprise high-performance fiber reinforced resin matrix composite materials. The fiber reinforcement is mainly composed of aramid fiber, ultra-high molecular weight polyethylene fiber, etc. The composition of ballistic resistant composites is often composed of a reinforcing fiber and a resin matrix, such as an aramid fiber reinforced polyurethane resin ballistic resistant composite, which results in the mechanical properties of the layers in the composite being exactly the same.
Studies have shown that [ Kong Chunfeng, tian Wei, weng Puying, kang Lingfeng, zhou Chengyan ] the impact resistance study of high performance fiber laminate composites [ J ]. University of Zhejiang university (Nature science edition), 2016,35 (03): 367-371], the face-facing fibers are prone to shear failure and the back-facing fibers are prone to tensile failure, so that the differential layering structural design of the face-facing and back-facing can effectively improve the ballistic performance of the composite. Therefore, there are studies on the preparation of ballistic composites [ Sun Jie, zhao Juan ] by using two or more fibers through a lay-up combination design, the application of fiber reinforced ballistic composites and the current research state [ J ]. Chemical fiber and textile technology, 2021,50 (01): 7-11+53], but only the characteristics of different types of fibers in mechanical strength, such as the high specific strength and high specific toughness of ultra-high molecular weight polyethylene fibers, the high strength characteristics of para-aramid fibers, and the like, are utilized to absorb energy only by using the deformation, fracture, debonding of the fibers.
Ballistic performance is a function of both energy absorption and energy diffusion transmission, but the prior art does not adequately consider the material design for another factor affecting ballistic performance, namely the rate of transmission of stress waves. The prior art does not combine designs based on the impact and stress wave transmission characteristics of the penetration body.

the reinforcement structure is unidirectional cloth (UD cloth) or fabric;
the thermoplastic resin is polyurethane and/or polyvinyl butyral and modified resin thereof.
The invention also provides a method for preparing the bulletproof composite material.
The method for preparing the bulletproof composite material provided by the invention comprises the following steps:
1) Respectively preparing a thermoplastic resin-based composite material taking high-strength high-modulus fibers as reinforcements and a thermoplastic resin-based composite material taking high-strength high-toughness fibers as reinforcements;
2) Layering the laminated plates: paving a plurality of layers of thermoplastic resin matrix composite materials taking high-strength high-modulus fibers as reinforcements to serve as an elastic facing surface, paving a plurality of layers of thermoplastic resin matrix composite materials taking high-strength high-toughness fibers as reinforcements to serve as a back elastic facing surface, and forming a laminated plate;
3) Placing the obtained laminated plate in a mould, and performing hot press molding to obtain the laminated plate;
In the step 1), the reinforcement is fiber UD cloth with the surface density of about 100g/m 2;
In the step 2), the design is carried out according to the modulus matching design requirement in a [0 degree/90 degree ] orthogonal layering structure;
In the above method step 3), the hot press forming temperature may be 100 to 150 ℃, preferably 125 to 135 ℃, more preferably 128 ℃, the hot press forming pressure may be 0.5 to 5MPa, preferably 0.5 to 2MPa, more preferably 1MPa, and the heat preservation time may be 5 to 50min, preferably 20 to 40min, more preferably 30min.
The tensile deformation and fracture of the fiber are the main energy absorption modes of the composite bulletproof target plate, and the size of the energy absorption modes depends on two aspects: one is the ability of the fiber to absorb energy. The energy absorption capacity of different fibers can be compared by the Cunnif energy absorption empirical formula [MIAO M.Dynamic modulus and strain wave velocity in ballistic fibre strands[J].Journal of Materials Science,2016,51(12):5939-47], and in general, the larger the tensile strength of the fibers is, the higher the breaking elongation is, and the better the energy absorption effect is. Thus, ballistic resistant composites require the use of high performance fibers. And secondly, the number of fibers involved in energy absorption. The bullet contacts the target plate, the fiber yarn directly contacting the bullet is the main yarn, and the other yarns are the secondary yarns. The primary yarn directly absorbs energy but occupies smaller space, and the secondary yarn occupies larger space, but the secondary yarn needs stress wave transmission to participate in energy absorption. The stress wave transmission rate depends on the density and modulus of the fiber, with the smaller the density and the greater the modulus, the faster the stress wave transmission. The invention considers the stress wave transmission and fiber energy absorption capacity simultaneously, uses high-strength and high-toughness fiber energy absorption, uses high-strength and high-modulus fiber to transmit stress waves, and makes the composite material fully play the anti-bullet capacity.
There have been many studies in the prior art regarding the absorption of energy. The invention focuses on solving the problem that the prior art does not fully consider the energy transmission and diffusion in the design of the composite material, and the faster the energy diffusion, the more yarns the surface of the target plate can participate in energy absorption, so the composite material designed in the way has higher specific absorption energy.
According to the invention, the high-strength high-modulus PI fiber is laid on the elastic face, the high-strength high-toughness PI fiber is laid on the back elastic face, and the high-strength high-modulus PI fiber and the back elastic face are combined through hot pressing to prepare the laminated board, so that the advantages of high stress wave transmission rate of the high-strength high-modulus PI fiber and high bulletproof efficiency of the high-strength high-toughness PI fiber are fully exerted.

Detailed Description
The preferred embodiments of the present invention will be described below with reference to the accompanying drawings, it being understood that the preferred embodiments described herein are for illustration and explanation of the present invention only, and are not intended to limit the present invention.
Example 1
In the embodiment, the high-strength high-modulus PI fiber is selected from the S30M type (tensile strength 3.1GPa, modulus 164GPa, elongation at break 2.1%, density 1.44g/cm 3, stress wave velocity C of 10691M/S calculated by formula (1)), the high-strength high-toughness PI fiber is selected from the S35 type (tensile strength 3.5GPa, modulus 123GPa, elongation at break 3.2%, density 1.44g/cm 3, ballistic performance calculated by formula (2)712 M/s).
The preparation method of the composite material bulletproof target plate with the modulus matching design comprises the following steps:
a. preparation of fiber UD cloth
Uniformly and parallelly arranging the S30M type fibers/S35 type fibers impregnated with polyurethane on a support film by using a winding machine to prepare S30M type fiber UD cloth/S35 type fiber UD cloth, wherein the surface density is about 100g/M 2;
b. Cutting sample wafer
Cutting the UD cloth prepared in the previous step into a sample wafer with the size of 300 multiplied by 300 mm;
c. Laminate ply
The [0 °/90 ° ] orthogonal ply structure design (i.e., the angle between each ply is 90 °) is performed according to the modulus matching design requirements, as shown in fig. 1. Number I: laying 60 layers of S35 type fiber UD cloth; II: laying 60 layers of S30M type fiber UD cloth; III and IV: the 12 layers of S30M type fiber UD cloth and 48 layers of S35 type fiber UD cloth are added, wherein the III sample adopts the S30M type fiber UD cloth side as an elastic facing surface, and the IV sample adopts the S35 type fiber UD cloth side as the elastic facing surface.
D. Laminated board hot pressing
And respectively placing the laminated plates I, II, III and IV in a die, performing hot press forming in a hot press, wherein the hot press forming temperature is 128 ℃, the hot press forming pressure is 1MPa, and the heat preservation time is 30min.
Table 1 shows the effect of the target board prepared in example 1
As can be seen from the data in table 1: the elastic resistance of the target plate I is better than that of the target plate II. This is because the tensile strength and elongation at break of the S35 type fiber are both higher than those of the S30M fiber, and the ballistic performance of the S35 fiber is higher than that of the S30M fiber according to the Cunniff ballistic performance empirical formula. After modulus matching design, the bulletproof efficiency of the III target plate is higher than that of the I target plate, and the III target plate is paved with part of S30M type high-strength high-modulus PI fibers on the bullet-facing surface, so that when a bullet contacts the target plate, the stress wave transmission speed is high, energy is rapidly diffused in the plane range of the target plate, and the number of the secondary yarns participating in energy absorption is increased. Meanwhile, the high-strength high-toughness S35 type PI fiber with the back elastic surface can play a very good role in energy absorption, so that the V50 value and the SEA value are obviously improved compared with those of a pure S35 fiber target plate and an S30M fiber target plate. However, when the bullet-facing surface adopts S35 type fiber and the back bullet-facing surface adopts S30M type fiber (sample plate IV), the bulletproof effect is obviously reduced, which is only slightly higher than that of a pure S30M type fiber target plate (sample plate II), and both fibers do not fully play respective roles.
Fig. 2 is a slice of a micro-nano focus CT scan in the thickness direction of the target plate. The preparation method of the target plate is the same as that of the embodiment 1, wherein a1, a2, a3 and a4 are high-strength high-modulus fiber welcome bullets, and the specific preparation method refers to the III target plate in the embodiment 1; b1, b2, b3 and b4 are high-strength high-toughness fiber welcome bullets, and the specific preparation method refers to the IV target plate in the example 1.
As can be seen from fig. 2, when the PI fiber with high strength and high model is on the bullet-facing surface, the layering of the target plate is spread in a fan-shaped manner, and more layering phenomenon is shown; when the high-strength high-toughness PI fiber is on the elastic face, the layering of the target plate is diamond-shaped, the layering area is obviously reduced, and the energy absorption effect is also reduced. More notably, when the face is a high strength, high modulus PI fiber, the fiber on the face side is substantially deformed and broken, indicating that there is sufficient fiber to participate in energy absorption and thus has a higher ballistic performance.
Fig. 3 is a graph showing a CT scanning pore distribution of a micro-nano focus on the bullet facing surface of a target plate. The preparation method of the target plate is the same as that of the embodiment 1, wherein (a) is high-strength high-modulus fiber welcome bomb, and the specific preparation method refers to the III target plate in the embodiment 1; (b) The specific preparation method refers to the IV target plate in the example 1 for the high-strength and high-toughness fiber welcome bullet
As can be seen from fig. 3, when the high-strength high-modulus PI fiber is on the spring-facing surface, the target plate is layered and radially and circumferentially spread around the impact point; when the high-strength high-toughness PI fiber is on the bullet-facing surface, the target plate is layered by taking the impact point as the center, and the cross-shaped layered morphology is presented along the fiber direction of the main yarn. The former was more damaged when the bullet was penetrated, indicating more fiber and resin involved in energy absorption.
The modulus matching design scheme provided by the scheme is proved by V50 test and micro-nano focus CT scanning: the high-strength high-modulus PI fiber is laid on the side of the elastic face, the high-strength high-toughness PI fiber is laid on the side of the back elastic face, and the performance advantages of the high-strength high-modulus PI fiber and the back elastic face can be fully exerted, namely the high-strength high-modulus fiber is beneficial to energy transmission, and the high-strength high-toughness fiber is beneficial to energy absorption. The two are well matched, and compared with other layering structure designs, the scheme has higher SEA value.
It will be apparent to those skilled in the art that various modifications and variations can be made to the present invention without departing from the spirit or scope of the invention. Thus, it is intended that the present invention also include such modifications and alterations insofar as they come within the scope of the appended claims or the equivalents thereof.
