Abstract

The invention discloses a preparation method of a reticular carbon fiber aluminum-based composite material. The preparation method comprises the following steps of preparing reticular carbon fibers and an aluminum base material, and staggering carbon fiber bundles by a cross plain weaving method to form the reticular carbon fibers; degumming the reticular carbon fibers, carrying out chemical nickel plating on the reticular carbon fibers by using an ultrasonic cleaning machine, specifically, deoiling, coarsening, sensitizing, activating and depositing; and carrying out near-solid-state cast-rolling compounding by adopting cast-rolling equipment. According to the preparation method, the carbon fiber pretreatment process comprising the three steps of surface activation, chemical nickel plating and constant-temperature heating is designed according to the specific distribution mode of the cross plain net-shaped carbon fibers, and excellent preconditions are provided for preparation of the net-shaped carbon fiber reinforced aluminum-based composite material; in the near-solid-state casting-rolling compounding process, the near-solid-state covering layer in the solidification stage can fully infiltrate the carbon fiber under the condition of ensuring the complete structure and stable distribution of the carbon fiber by virtue of proper self flowability and reasonable external pressure; and the prepared cross plain reticular carbon fiber reinforced aluminum-based composite board can realize multi-angle reinforcement in a two-dimensional space.
