Abstract
A method for manufacturing a composite article is described that includes a step of impregnating a reinforcing fabric with a semi-aromatic polyester composition in the molten state, having a melt viscosity η of 20 Pa·s to 200 Pa·s. The reinforcing fabric can be maintained at a temperature of plus or minus 50° C. relative to the melting temperature of the polyester.
