IN-PLANE MECHANICAL PROPERTIES OF EMBEDDED ANDCO-CURED STITCHED DAMPING COMPOSITE STRUCTURE

Abstract

Abstract: In order to improve the in-plane mechanical properties of composites, an orthogonal symmetric embedded and co-cured stitched damping composite structure is presented. A numerical simulation model of the equivalent elastic parameters of the structure was established. The embedded and co-cured stitched damping composite specimens were manufactured by the medium temperature co-curing process of the autoclave. The tensile test of the universal testing machine verified the effectiveness of the numerical simulation method. The effective ANSYS finite element model is used to further analyze the variation of the in-plane equivalent elastic parameters E_x, E_y, G_xy and ν_xy with the stitch length, line spacing and damping layer thickness. It lays a foundation for the study of mechanical properties of embedded co-cured stitched damping composites.

Key words: embedded co-cured suture damping structure, elastic modulus E_x,E_y, shear modulus G_xy, poisson′s ratio ν_xy, composites
