Abstract

The invention discloses a forming method for continuous fiber reinforced metal matrix composite parts. The forming method specifically comprises the following steps that step 1, matrix-containing metal photocurable slurry is prepared; step 2, continuous fibers are pretreated; step 3, blanks of composite parts are subjected to solidification forming; step 4, the blanks are subjected to post-processing; and step 5, degreasing sintering is carried out to obtain the required parts. The forming method for the continuous fiber reinforced metal matrix composite parts solves the problems of complicated process and long cycle time in the prior art.

Description

technical field [0001] The invention belongs to the technical field of composite material preparation, and relates to a forming method of a continuous fiber reinforced metal matrix composite material part. Background technique [0002] Due to its light weight, high temperature resistance, high specific strength, high specific modulus, good wear resistance, good fatigue resistance, and good aging resistance, continuous fiber reinforced metal matrix composites have excellent comprehensive properties in the fields of national defense, military industry, aerospace and other fields. Broad application prospects. At present, there are two forming methods for this type of material: solid-state method and liquid-state method. The solid-state forming method is to use the solid-phase diffusion of atoms in the contact part to realize the combination under the conditions of high temperature and small plastic deformation; the liquid-state forming method is to preform the fiber after formi...
