Abstract

The integration of fiber reinforced polymers and novel lightweight design strategies in aircraft interiors offers the potential to reduce the empty take-off weight of commercial aircraft and thus decrease CO2 emissions during operation. In order to meet the mechanical requirements of high load-bearing inserts in sandwich structures, effective distribution of localized forces across the face sheets is crucial. This study introduces a lightweight design that incorporates compression-molded hardpoints and spiderweb-like fiber tapes to spread loads into cabin partition walls. Utilizing a multiscale approach, the design is evaluated through virtual and experimental testing, allowing for future development of digital twin models. Physical testing demonstrates significant mass savings and improved load capacity, with one design variant achieving a 50% weight reduction while maintaining 70% pull-out strength and exhibiting a more gradual failure mechanism compared to the conventional design.
