Description
Technical Field
The present invention relates to a method of reinforcing fibers.
Background
Since ancient times, human life is closely related to fiber, and natural fibers such as cotton and hemp are used worldwide. The development of chemical fiber goes through three stages of artificial fiber, synthetic fiber and chemical fiber, and along with the improvement of fiber production technology, not only fiber products occupy greater and greater specific gravity in the market, but also the application of the fiber is deep in various fields. As an important basic engineering material, the performance of the fiber needs to be higher standard while the chemical industry and the material science develop.
In recent years, the development of composite disciplines and the development of nanocomposites have made tremendous progress, mainly thanks to the increasing development of nanomaterials and nanotechnology. The emergence of nanomaterials with a variety of shapes, sizes and compositions lays a solid foundation for the design, research and development of multifunctional composites. Composite materials composed of nanomaterials such as nanotubes, nanoflakes, nanofibers, etc. may combine two or more of the excellent properties of the raw materials used, such as good mechanical or thermal stability after the inherently unstable materials are compounded with the nanomaterials. When the nano material is used as a reinforcing phase, the matrix material can be endowed with outstanding properties, and some characteristics inherent to the material can be maintained or improved.
Kevlar fiber is a high performance fiber material developed by Dupont, Inc. in the twentieth sixty years. It belongs to para-type aromatic polyamide organic fiber, and has the advantages of high strength, low density, high temperature stability, chemical corrosion resistance, etc. The specific gravity of the Kevlar fiber is only 1.44g/cm3Only 1/5 of steel and 1/2 of glass fiber, but the strength is 5 times of steel and 2 times of glass fiber. These properties are outstanding among known fiber materials, but the tensile strength of kevlar fibers is still not usable in specific applications, and the tensile strength of kevlar fibers needs to be further improved, but the kevlar fibers have low reactivity and are difficult to further improve by a surface chemical modification method.
