Abstract: This paper introduces the research results of removing excess adhesive from samples with different pre- preg layers in the process of glass fiber autoclave molding under vacuum. It has been confirmed through a series of experimental studies that when calculating the excess adhesive,its viscosity and service life,as well as the thick- ness and permeability of the filler must be considered,depending on applied autoclave pressure value.
