Embodiment 1

[0033] Test materials: high-purity titanium foil thickness 30um, high-purity titanium foil thickness 100um, high-purity aluminum foil thickness 30um, SiC fiber, titanium alloy honeycomb, energy-absorbing and shock-absorbing high-elastic resin-based composite material; armor length and width are 100mm, The thickness is 30mm.

[0034] The specific implementation steps are as follows:

[0035] Step 1. First, surface-treat the high-purity titanium foil and aluminum foil, clean them, and then cut the titanium foil and aluminum foil into 100mm×100mm squares;

[0036] Step 2: Cut the SiC fiber into 100mm×100mm cubes after being wound by an automatic winding machine; a layer of transition metal can be deposited on the surface of the reinforcing fiber by means of magnetron sputtering, and then the fiber is wound by a fiber winding machine.

[0037] Step 3. Stack titanium foil (30um), aluminum foil (30um), titanium foil (100um), SiC fiber, titanium foil (100um) and aluminum foil (30um)...

Embodiment 2

[0043] Test materials: high-purity titanium foil thickness 50um, high-purity titanium foil thickness 100um, high-purity aluminum foil thickness 50um, SiC fiber, titanium alloy honeycomb, energy-absorbing and shock-absorbing resin-based composite materials; armor length and width are 100mm, and thickness is 30mm. The thickness of the high-purity titanium foil and aluminum foil used in step 1 was changed to 50um, and the remaining specific implementation steps were the same as in Example 1.

Embodiment 3

[0045] The thickness of high-purity titanium foil is 100um, the thickness of high-purity titanium foil is 100um, the thickness of high-purity aluminum foil is 70um, SiC fiber, titanium alloy honeycomb, energy-absorbing and shock-absorbing resin-based composite materials; the length and width of the armor are 100mm, and the thickness is 30mm. The high-purity titanium foil used in step 1 was changed to 100um and the thickness of the aluminum foil was changed to 70um, and the rest of the specific implementation steps were the same as in Example 1.

Abstract

The invention relates to a multi-component toughened bionic structural armor and a preparation method thereof. The armor is of three-layer composite structure, specifically, the upper layer and the lower layer of the structure refer to mixed arranged layers of ultra-hard intermetallic compound layer and fiber-reinforced composite layer, and the middle layer refers to an energy-absorbing and vibration-reducing layer formed by filling titanium honeycomb structure with high-elasticity resin-based composite material. Further, the upper layer and the lower layer are prepared by the steps of sequentially laminating titanium foil, aluminum foil, titanium foil, fiber-reinforced composite layer, titanium foil layer by layer sequentially gradually to obtain a preform and then sintering the preform;the armor is prepared by composing the upper layer and the lower layer with the titanium honeycomb structure, and then filling the titanium honeycomb structure with the energy-absorbing and vibration-reducing composite material. Since the rigid restraint structure that multiple material systems are utilized to achieve composition of toughness and hardness, similar materials are utilized as a matrix, and the honeycomb structure is filled with the energy-absorbing and vibration-reducing resin-based composite material is utilized, scientificity of the integral structure is guaranteed while the problem of difficulty in composition of heterogeneous materials is solved and protective capacity of the armor is improved.

Description

technical field [0001] The invention relates to a multi-component composite toughened bionic structural armor and a preparation method thereof, belonging to the technical field of metal matrix composite materials. Background technique [0002] Regarding the upgrading of armed helicopters, in addition to improving their weapons and equipment, it is also necessary to improve their body's anti-bullet capability to improve their battlefield survivability. For this reason, the key parts of modern armed helicopters, such as the bottom of the helicopter, around the cockpit, the fuel tank, the side walls of the cabin, and the wings, have adopted new protective materials. For example, the American AH-64 "Apache", its fuselage, cockpit, rotor, fuel tank and transmission system are all made of composite materials, which can ensure that the helicopter can continue to fly for 30 minutes after being hit by a 12.7mmAMP bomb and a 23mmHEIT bomb. Above, the helicopter can safely withdraw fr...
