Detailed Description
In order to solve the problem of high mass of the vibration absorbing material, the vibration absorbing material is designed into a honeycomb structure, and the energy absorption and vibration reduction effects of the material with the honeycomb structure are poor.
Bird feathers show excellent capability of absorbing flight vibration in the process of bearing complex pneumatic load, do not generate obvious noise phenomenon similar to that generated by wind blowing flags or leaves, and show excellent mechanical property. Bionic research shows that the characteristics of light weight, high strength, vibration absorption and noise reduction of the bird feather greatly benefit from the material and structural characteristics of feather shaft medulla. The medulla is the core in the feather shaft, is a closed foam-like structure, has a hierarchical structure of porosity and very small mass on the micro-scale and nano-scale. The foam structure is composed of hollow ball chambers, the chambers are formed by weaving keratin fibers (the fiber diameter is about 40-130 nm), chamber walls are formed, the chambers are tightly connected, and nanoscale pores are reserved among the connected fibers, so that the density is further reduced. The cavity walls are connected and reinforced through the fiber support plates to form a fiber core body vibration absorption structure similar to a grid shape, light foams are filled in cavities of the grid structure, namely the cavity, the foams have strong telescopic capacity, can absorb most of energy generated in a loading process, conduct part of energy back to the grid fiber structure, and absorb and dissipate vibration energy through microcracks, crack deflection and fiber bridging among the cavity wall fibers forming the grid structure in a medullary part.
Inspired by the material and structural characteristics of feather shaft medullary of bird feather, the inventor intends to adopt the mutual coupling and synergistic effect of a unique energy-absorbing structure and light energy-absorbing filler to improve the overall performances of the material, such as mechanical property and the like. Therefore, the invention provides a bionic vibration-absorption composite material and a preparation method and application thereof, and the invention is further described in detail below in order to make the purpose, technical scheme and effect of the invention clearer and clearer. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Referring to fig. 1 to 3, an embodiment of the present invention provides a bionic vibration-absorbing composite material, where the composite material includes a vibration-absorbing core 1 and two unidirectional fiber cloth layers 2, and the two unidirectional fiber cloth layers 2 are respectively laid on an upper surface and a lower surface of the vibration-absorbing core 1; the vibration absorption core body 1 comprises a grid-shaped core body 11, light vibration absorption fillers 12 and reinforcing fibers 13, wherein cavities are distributed in the grid-shaped core body; the light-weight vibration-absorbing filler 12 is filled in the cavity of the lattice-shaped core 11, and the reinforcing fiber 13 is continuously inserted into the lattice-shaped core 11 filled with the light-weight vibration-absorbing filler 12 to reinforce the lattice-shaped core 11 and the light-weight vibration-absorbing filler 12.

Referring to fig. 4a-4b, in one embodiment, the lattice core 11 includes a plurality of intersecting fiber-resin layers 111, an array of transverse fibers 112 passing through the intersecting fiber-resin layers 111, and an array of longitudinal fibers 123 distributed between adjacent intersecting fiber-resin layers 111. The net-shaped core body with the structure has the effects of homogenizing stress, transmitting load and preventing local over-stress.
In one embodiment, the unidirectional fiber cloth layer 111 is formed by spreading unidirectional fiber cloth impregnated with resin in the axial direction; the thickness of the unidirectional fiber cloth layer 111 is 1-2 mm (such as 1mm, 1.5mm and 2 mm); and/or
The thickness of the latticed core body 11 is 3-5 mm; such as 3mm, 4mm, 5 mm.
In particular, a unidirectional fabric refers to a fabric having a large number of filaments in one direction (usually the warp direction) and only a small number and usually fine filaments in the other direction, so that the full strength of the unidirectional fabric is in the same direction. Therefore, the unidirectional fiber cloth layers with the thickness in the axial strength direction are paved on the upper surface and the lower surface of the grid core body, and the bending resistance and the tensile resistance of the bionic vibration absorption composite material are enhanced.

That is, the reinforcing fibers 13 may reinforce the lattice-shaped core 11 and the light-weight shock-absorbing filler 12 in a stitch-type (i.e., reciprocating perpendicular to the intersecting fiber-resin layers 111 as shown in fig. 1 to 3 and 5a to 5 d) or a cover-type (i.e., reciprocating parallel to the intersecting fiber-resin layers 111 as shown in fig. 6a to 6 c). Specifically, the two reinforcement modes can enhance the structural stability of the vibration absorption core body and prevent the vibration absorption core body from structural damage when absorbing vibration energy. The two modes of reinforcement lead to different attenuation paths of the vibration waves: in the suture type reinforced vibration absorption core structure, the attenuation of vibration waves is mainly dissipation, the fiber layers (namely cross fiber-resin layers) of the vibration absorption core are sutured through reinforcing fibers to form a unified whole, when the core load deforms, the reinforcing fibers participate in the transmission of the vibration waves through fiber bridging, and the vibration energy is homogenized and dissipated, so that the strength of the bionic vibration absorption composite material is improved, the high specific strength characteristic of the fibers can be fully exerted, and the bionic vibration absorption core structure is more suitable for engineering fields with strict requirements on the strength of the vibration absorption material and high vibration energy, including aerospace, rail transit and the like; in the reinforced core structure that shakes of cladding formula, the weakening of vibration wave is with absorbing as leading, become whole with core fiber and internal packing cladding through continuous reinforcement fibre, the vibration wave is in the internal transmission of shaking filler and core structure of shaking, through the fibrous cladding effect of reinforcement, keep shaking the major structure that shakes and be the core and shake the holistic stability of filler, guarantee that vibration energy is absorbed and weakened at core structure and between shaking the filler, outwards transmit, full play the energy-absorbing characteristic of the internal vibration absorption filler, be applicable to vibration intensity low, require harsh engineering field to the noise, like precision machine tool, the vibration absorption of precision instrument is fallen and is fallen.
