Compression Properties of Syntactic Foam Reinforced by Warp-knitted Spacer Fabric: Theoretical Compression Strength Model and Experimental Verification

In this study, a theoretical model based on the fiber buckling theory was established to predict the compression strength of a new type of syntactic foam, namely the syntactic foam reinforced by the warp-knitted spacer fabric (SF-WKSF). In order to verify the availability of this model, compression...

Description
Summary:In this study, a theoretical model based on the fiber buckling theory was established to predict the compression strength of a new type of syntactic foam, namely the syntactic foam reinforced by the warp-knitted spacer fabric (SF-WKSF). In order to verify the availability of this model, compression strength values of theoretical simulations were compared with the experiment results. The comparison results showed that the model can accurately simulate the compression strength values of different SF-WKSF samples with slight deviation. Finally, the causes of deviation was analyzed in detail.
