Abstract

The invention discloses a low temperature resistant aluminum alloy composite material and a preparation method thereof. The composite material comprises are composed of a substrate, continuous fiber reinforcements and whisker reinforcements. The substrate comprises, by mass, 2.0%-3.0% of Li, no more than 0.10% of Si, no more than 0.1% of Fe, 2.4%-3.0% of Cu, 0.4%-0.8% of Mn, 0.8%-1.4% of Mg, no more than 0.05% of Cr, 0.10%-0.2% of Zn, 0.08%-0.15% of Zr, no more than 0.15% of Ti and the balance Al. The continuous fiber reinforcements are carbon fiber bundles, and account for 30%-50% of the substrate in volume, and the whisker reinforcements are Al2O3, and account for 5%-10% of the substrate in volume.

Description

technical field [0001] The invention belongs to the field of materials, and in particular relates to a low-temperature resistant aluminum alloy composite material and a manufacturing method. Background technique [0002] With the increase of drilling and scientific research work in the arctic and antarctic regions, the transportation of drilling equipment is a prominent problem due to the harsh environment in the alpine regions. To ensure the smooth progress of drilling work, the load capacity of drilling equipment must be considered. Compared with steel drill rods, aluminum alloy drill rods have the advantages of light weight, fatigue resistance, high flexibility, corrosion resistance, cold resistance, and high critical speed. At present, more than 20 countries have started the development and application of aluminum alloy drilling rods. The use of aluminum alloy drill pipe can reduce the load capacity of the drilling device, improve the transportation capacity and install...
