The energy-absorbing characteristics of two-dimensional periodic self-reinforced polypropylene (SRPP) sandwich panel

This paper is used the slotting technique to manufacture self-reinforced polypropylene (SRPP) sandwich structure. The crashworthiness characteristics of structures were measured as a function relative density. In this research, particular focus placed on examining energy-absorbing with honeycomb and star cores. It was concluded that SRPP panel core length 60 mm provided best characteristics. Moreover, it shown height structure 30 more stable than height. addition, indicated failure behaviour highly sensitive density Furthermore, could potentially be an alternative lightweight material for recyclable structures.
