Embodiment 1

[0034] The continuous bundle SiC ceramic fiber is pretreated, the fiber is placed in a box-type resistance furnace, the holding temperature is 650-700°C, and the holding time is 1.5h to remove the thermal decomposition coating on the surface of the fiber, and then the surface of the fiber is cleaned with alcohol. Then use an ultrasonic cleaning machine to clean the fibers (15-20 min) at a temperature of 30° C. to 40° C. to remove remaining coating particles and impurities, and finally dry the fibers. The 0.15mm Al foil was cut into 24mm×800mm aluminum strips. After drying treatment, they are stacked in the order of "Al tape-SiC bundled fiber-Al tape", and the bundled SiC fibers are laid along the length direction of the aluminum tape.

Embodiment 2

[0038] Al 2 o 3The ceramic fiber is pretreated, the fiber is placed in a box-type resistance furnace, the holding temperature is 600-650°C, and the holding time is 0.5h to remove the thermal decomposition coating on the fiber surface, then clean the fiber surface with alcohol, and then use an ultrasonic cleaner The fibers are cleaned (15-20 min) at a temperature of 30°C to 40°C to remove remaining coating particles and impurities, and finally the fibers are dried. The 0.15mm Al foil was cut into 24mm×800mm aluminum strips. After drying according to "Al belt-Al 2 o 3 Bundle fiber-Al ribbon" stacked sequentially, bundle Al 2 o 3 The fibers are laid along the length of the strip.

[0039] Consolidate the aluminum strip with an ultrasonic consolidation device to prepare aluminum strips with uniform fiber distribution: at room temperature, the pressure of the indenter of the ultrasonic consolidation device is 125-150kgf, the amplitude of the ultrasonic wave is 20-40μm, and th...

Abstract

The invention relates to an ultrasonic consolidation rapid manufacturing method for a continuous ceramic fiber uniform-distribution aluminum strip. According to the pretreatment technological parameters of SiC ceramic fibers and Al2O3 ceramic fibers, the holding temperature ranges from 600 DEDG C to 700 DEG C, and the holding time is 1.5 h and 0.5 h. According to the manufacturing technological parameters of the pretreated bundle ceramic fiber uniform-distribution aluminum strip, at normal temperature, the added load ranges from 125 kgf to 150 kgf, the amplitude ranges from 20 microns to 40 microns, and the speed ranges from 30 mm / s to 50 mm / s. Bundle fibers in the manufactured fiber uniform-distribution aluminum strip are scattered and distributed uniformly, and are well bonded with the aluminum strip, the interface bonding situation is good, aluminum strips are bonded closely and have no obvious interface, and the rapid forming manufacturing method can be used for manufacturing the ceramic fiber uniform-distribution aluminum strip.

Description

technical field [0001] The invention relates to a preparation method of a composite material, in particular to the structural design of a continuous ceramic fiber aluminum strip and an ultrasonic consolidation rapid manufacturing method of a fiber uniformly distributed prefabricated aluminum strip. Background technique [0002] Due to the ceramic fiber (Al 2 o 3 , SiC) have low density, high modulus, high strength, high temperature resistance, corrosion resistance and other excellent properties, and have been widely used in light metal (such as aluminum alloy, titanium alloy and magnesium alloy, etc.) matrix composite materials and their parts. However, at present, short fibers are mainly used, while continuous long fibers, especially bundled long fibers, are difficult to disperse manually, easy to break when laying, uneven distribution and uneven performance in composite materials and parts, etc. It has affected the promotion and application of continuous long fibers. Fo...
