The Effect of Spacer Yarn Arrangement on Compression Behaviors of Novel Flexible Foam-Core Sandwich Composites

Abstract:

In this study, a kind of novel flexible foam-core sandwich composite was involved. The flexible foam-core sandwich composites were fabricated based on 3D warp-knitted spacer fabrics. The foam-core was filled in the spacer fabric by using a kind of modified hydrophilic polyurethane foam. In order to investigate the effect of spacer yarn inclination angle on the compression behaviors. A compression test was carried out. The compression stress-strain curve was used to analyze the effect of 3D warp-knitted spacer fabric spacer yarn arrangement. According to the experiment results, it indicates that the spacer yarn arrangement could influence the anti-compression capacity of the sandwich composites obviously. Therefore, the spacer yarn arrangement of 3D warp-knitted spacer fabrics can be changed to meet specific end-use requirement for foam-core sandwich composites.
