Dynamic response of polyurethane foam and fiber orthogonal corrugated sandwich structure subjected to low-velocity impact

Yuezhao Pang et al.

Summary: This study prepared two types of foam/fiber sandwich structures using the Vacuum Assisted Resin Transfer Molding (VARTM) process and conducted low-velocity impact tests to investigate their force response, specific energy absorption, and failure modes under different impact energies, hammer shapes, and impact positions. The results showed that the corrugated sandwich structure exhibited superior low-velocity impact resistance compared to the flat sandwich structure, and performed best when impacted at the corrugated trough position.

Keyu Zhu et al.

Summary: A novel all-composite sandwich panel with channel core was proposed to enhance compressive strength and energy absorption characteristics. Experimental and numerical analysis results showed that the proposed structure exhibited better compressive strength and specific energy absorption compared to the traditional corrugated core sandwich panel. Further optimization of the structural efficiency through foam filling significantly increased the compressive strength and energy absorption.

Behaviour of continuous fibre composite sandwich core under low-velocity impact

Sartip Zangana et al.

Summary: The study found that increasing core thickness improved impact capacity, while increasing core height decreased sandwich strength. Finite element analysis simulated the damage status and mechanism of the novel composite core sandwich. The multi-cell composite corrugated core increased impact capacity, and the trapezoidal composite corrugated sandwich core showed higher specific strength compared to traditional honeycomb, truss, and foam cores.

Energy absorption properties of macro triclinic lattice structures with twin boundaries inspired by microstructure of feldspar twinning crystals

Yijie Bian et al.

Summary: Inspired by the microstructure of triclinic crystal material, lattice structures with twin boundaries were designed for energy absorption application. Introducing twin boundaries controls deformation mode and improves energy absorption performance, with both TCs and TBCCs showing increased energy absorption with more twin boundaries. The designed structures also follow the Hall-Petch relationship, confirming the feasibility of designing novel lattice structures by mimicking material microstructures.

Compression behavior of a novel sandwich structure with bi-directional corrugated core

Lei Ge et al.

Summary: A novel sandwich structure with bi-directional corrugated core has been designed and manufactured using 3D-printing technology. The compression response and failure modes of this structure have been studied, showing that buckling and fracture of corrugations are the main failure modes in flatwise compression. The analytical model developed has shown good agreement with results from FEM and experimental methods. This design has demonstrated better compression properties compared to conventional single-corrugated core structures.
