Abstract: In this article, 3-dimensional sewed sandwich composite is made by using flexible epoxy resin and different reinforcing materials, providing better damping performance and higher structural strength. By testing each performance of the 3D sewed sandwich damping composite, it is concluded that: for 3D sewed structure, it is best to use epoxy resin composite for structural layer and aramid fiber reinforced polymer (AFRP) for damping layer to reinforce the flexible epoxy resin, which provides a damping ratio of 3.33%, bending modulus of 14.3GPa, bending strength of 290MPa, and impact toughness of 338kJ/m2.

Key words: 3D-sewed, damping, epoxy resin, composite material, sandwich structure
