Problems solved by technology

These reinforcements are not only expensive, but even strategic materials (such as silicon carbide fibers) are not easy to obtain; moreover, there are also wetting problems with the matrix zinc alloy, which makes the preparation process of composite materials too complicated
For a long time, this high cost has greatly restricted the application of zinc-based composites

Embodiment 1

[0020] Take 100 μm high-strength steel fibers as the warp direction, and 10 μm steel fibers as the weft direction of the fixing effect, and make the volume content of steel fibers reach 80% by weaving, and at the same time carry out four-roll prefabricated woven two-dimensional mesh-like reinforcements. For hot-dip galvanizing treatment, the four composite foils that have just come out of the galvanizing liquid surface are rolled and quickly blown to cool, then immersed in a cooling pool, and cooled to below 100°C by water to obtain a 1mm composite sheet.

Embodiment 2

[0022] Both the warp direction and the weft direction take 38 μm stainless steel fibers, and weave them according to the 350-mesh screen process, so that the volume content of stainless steel fibers reaches 30%. Hot-dip galvanized aluminum alloy treatment to the prefabricated woven 350-mesh mesh reinforcement to obtain a composite foil, and wind the composite foil just out of the plating solution into a rod shape (the winding direction is the radial direction of the rod, the prefabricated body or composite The width direction of the foil is the length direction of the rod). Quickly immerse the bar into a cooling pool, cool it below 100°C, and obtain a composite bar with a diameter of 3mm.

Embodiment 3

[0024] Both the warp direction and the weft direction are 25 μm stainless steel fibers, which are woven into a 500-mesh sieve. At the same time, two rolls of prefabricated woven 500-mesh screens are hot-dip galvanized aluminum alloy to obtain composite foils, and the two composite foils are wound into pipes with an outer diameter of Φ15mm×Φ10mm through a winding shaft, and the rods are quickly immersed in the cooling pool and cooled to Below 100°C, a composite pipe with a volume content of stainless steel fibers reaching 50% is obtained.

Abstract

The invention relates to a continuous-steel-fiber-reinforced zinc-base composite material and a preparation method thereof. The composite material is composed of 30-80% of continuous high-strength steel fiber or stainless steel fiber and zinc alloy base. The preparation method comprises the following steps: weaving steel / stainless steel fiber into a two-dimensional grid according to the fiber content and reinforcement direction of the designed composite material; carrying out hot galvanizing on the alloy, and compacting the meshes to obtain a composite foil; and carrying out rolling, winding and the like to press the incompletely condensed composite foil into a plate, rod, tube or the like, and finally, quickly cooling to obtain the composite material. The composite material provided by the invention enhances the strength and application temperature of the zinc alloy, lowers the linear expansibility of the zinc alloy, and improves the fatigue resistance and creep resistance of the zinc alloy; and the zinc-base composite material has the advantages of low production cost, simple preparation technique and the like.

Description

technical field [0001] The invention relates to the technical field of new materials, in particular to a continuous steel fiber reinforced zinc-based composite material and a preparation method thereof. Background technique [0002] Zinc alloy has superior mechanical properties, good low temperature casting performance and processing performance, and has been more and more widely used in many fields such as machinery, electronics and chemical industry. However, its heat resistance is poor, and it can only be used below 100°C, which greatly limits its scope of application and life. Zinc-based composite materials overcome the shortcomings of zinc alloys in the high temperature range, such as large loss of strength and hardness, and large linear expansion coefficient, and obtain high high temperature strength, excellent wear resistance, high hardness and elastic modulus, and significantly improve Improve the fatigue life and high temperature creep resistance, reduce the coeffi...
