Abstract

This study introduces a novel self-reinforced sandwich panel design, incorporating a low-density polypropylene (PP) corrugated core between self-reinforced polypropylene (SRPP) face sheets. This structure aims to achieve high energy absorption, good toughness, low density, and full recyclability, addressing key challenges in composite materials for transportation and other industries. Using Abaqus/Explicit, a numerical analysis of the low-velocity impact response was conducted. A nonlinear, 3D finite element model was developed to predict both interlaminar (delamination) and intralaminar (fiber and matrix damage) failure modes, employing Hashin damage criteria and surface-based cohesive behavior. The research demonstrates that damage initiation and appropriate failure criteria can be predicted from the elastic response of the models, offering valuable insights into the performance of these innovative, environmentally friendly sandwich panels under impact conditions.
