Abstract

Abstract: In order to study the permeability and compression characteristics of thick layer-up fabrics, the fabrics with different plies were measured by radical permeability and unidirectional permeability teat method. The change of fabric thickness during radical permeability test was used to analyze the compression characteristics of thick layer-up fabric. The results indicate that the permeability of thick layer-up fabric is greatly affected by the thickness of fabric. As the thickness of the fabric layer increases, the permeability of the fabric in all directions decreases; when the VARTM is used to make thick layer-up composite, the thickness of fabric changes with the process. The thickness of the fabric is mainly affected by the gaps between the layers and fiber pores during the vacuum. The thickness of layer-up fabric is affected by the fiber state during the infusion. The research results provide references for the refined manufacturing of large-scale thick layer-up composite.

Key words: VARTM, thick layer-up fabric, permeability, compression characteristics
