Abstract: A method for manufacturing a composite product, including: 1) preparing a composite powder including 10-50 v. % of a polymer adhesive and 50-90 v. % of a chopped fiber; 2) shaping the composite powder by using a selective laser sintering technology to yield a preform including pores; 3) preparing a liquid thermosetting resin precursor, immersing the preform into the liquid thermosetting resin precursor, allowing a liquid thermosetting resin of the liquid thermosetting resin precursor to infiltrate into the pores of the preform, and exposing the upper end of the preform out of the liquid surface of the liquid thermosetting resin precursor to discharge gas out of the pores of the preform; 4) collecting the preform from the liquid thermosetting resin precursor and curing the preform; and 5) polishing the preform obtained in 4) to yield a composite product.
