Description
Technical Field
The invention relates to a device and a method for processing a continuous folding type vibration-damping and auxetic textile composite material, belonging to the field of textile materials and technologies.
Background
"auxetic materials", also known as "negative poisson's ratio materials", differ from traditional positive poisson's ratio materials in that they expand laterally when stretched longitudinally; when compressed longitudinally, a pinching effect occurs in the transverse direction. Below the pressure point, the conventional material collapses and thins, while the "auxetic material" compresses and hardens more quickly. The material actually becomes thicker, rather than thinner, when stretched. One of the structural properties of the auxetic material is improved by the indentation resistance. When the material is impacted, the "flow" and density of the material in the impacted area increases for non-auxetic materials, resulting in a decrease in the stiffness of the material. But for a dilatant material, the impact causes expansion of the material in the surrounding area, which action results in an increase in the density of the material below the impact. As a result, the hardness (indentation resistance, H) of the material increases to resist impact ". In recent years, researchers have noticed that even if a pomelo falls from a high place, the pomelo cannot crack, and the pulp is hardly damaged, because the honeycomb-shaped pomelo peel has good impact resistance, and the self-weight is light, which is equivalent to a self-damping effect, and the structure of the pomelo peel is called as an "auxetic material" in materials science.
Researchers in BMW groups improve the layered structure and the fiber trend in the existing fiber composite material according to the principle structure of the 'auxetic material' of the grapefruit, produce a new material with excellent protection effect, and creatively combine the functions of anti-collision, anti-impact, shock absorption and the like. The results of current research have been beyond expectations, with new materials being lighter, stronger, more stable than those currently used, with performance improvements of up to 20%. The innovative material can be produced and processed in an economic way, and has good industrial production application prospect.
With the continuous development of science and technology, new materials come out one after another, and composite materials required in the fields of bulletproof, aviation, navigation and the like are changed from initial metal materials, polyamide composite materials, glass fiber composite materials and the like to ultrahigh molecular weight polyethylene fiber composite materials, high-strength high-modulus carbon fiber composite materials, aramid fiber composite materials and the like. The high-performance fiber is mainly applied to materials in special fields in four types of one-dimensional fiber, two-dimensional fabric, three-dimensional fabric and weftless fabric.
The application of the negative Poisson's ratio effect to the fields of bulletproof, stab-resistant, earthquake-resistant, noise-reducing, marine navigation and the like is a great development trend in the future. The folding type auxetic textile composite material prepared by the invention not only has excellent mechanical property and noise reduction function, but also has the advantages of light weight and ventilation, can save energy consumption when being used in the field of aerospace, and can enable athletes to freely move when being used in sports goods. Helmets made with the composite material of the invention weigh much less than conventional products on the market, but provide the same level of protection.
At present, most of foams in China market are petroleum-based foams such as Polyethylene (PE), polypropylene (PP), Polystyrene (PS), polyvinyl chloride (PVC), polyethylene terephthalate (PET) and the like, and the foams are widely applied to packaging of industrial products such as electronics, precision equipment and the like and living goods. However, these petroleum-based foam packaging materials are difficult to degrade and have been used in some foreign restrictions. In addition, the raw materials for the preparation of these foamed packaging materials are derived from petroleum, which is a non-renewable energy source. With the development and utilization of people being increasingly reduced, the search for new materials to replace petroleum-based foam packaging materials is urgent.
The biomass foam packaging material has the advantages of rich sources, reproducibility, degradability and the like. Therefore, the adoption of biomass materials instead of petroleum-based materials in the field of packaging has become a hot spot of research in various countries. The foam used in the invention does not need to have excellent mechanical properties, and is discarded after being used for a certain number of times, so that degradable biological foam is selected.
