New bio-based honeycomb panel with a core in Arundo donax rings and flax/epoxy composite skins: Experimental tests and numerical model validation

Journal of Sandwich Structures & Materials, Journal Year: 2025, Volume and Issue: unknown

Published: April 10, 2025

Honeycomb sandwich panels are widely used in multiple building sector applications like non-structural lightweight for partitions, floating floors, insulation panels, or furniture. These typically consist of three layers: two thin rigid external layers and a thick low-density internal layer with honeycomb geometric shape. To reduce environmental footprint, eco-friendly materials encouraged. In this study, we propose an innovative panel core made Arundo donax rings skins flax fibre-reinforced epoxy composite. is highly invasive reed southern Europe. Its rapid growth makes it environmentally advantageous as can absorb significant amount CO 2 which then sequestered the panel, enhancing panel’s sustainability compared to existing alternatives. The produced through thermocompression mechanically tested using pull-off tests three-point bending. A key novelty research detailed investigation lateral surface roughness rings, has never been studied before. study explores how different levels affect adhesion between skins, individual within core, well mechanical bending properties panel. results show that polishing treatment significantly impacts all flexural properties, especially when performed on surfaces rings. particular, increased strength by 24.25 %, shifting from 19.06 MPa 25.16 MPa. Numerical simulations conducted employing Finite Elements cohesive contacts By adjusting parameters interface, model account accurately replicate experimental results. Once calibrated, serve design tool.

Abstract In most of the automobile and aerospace materials, cellular structures are extensively used due to their lightweight high energy absorption capabilities. Naturally available animal bones plant stems light in weight natural structures. This may inspire various researchers for integrating lattice such as beam, planar, triply periodic minimal surfaces, voronoi on structural materials. The development using 3D printing technology has opened up major attention towards fabricating components without any complications. this study, detailed crashworthiness responses compressive strength was optimized terms varying topology‐related factors carbon fiber reinforced polyethylene terephthalate glycol (CF/PETG) composite. experimentation conducted concerning variable topology shell thickness, unit cell type, wall thickness (WT), orientation (UCO), skewing angle, size. model examined by means Taguchi optimization technique. response analyzed compression test moreover, experimental is processes. From observation, which contributed more higher will be UCO 65.47% WT 15.20%. Results regression study show that R square value with concern 92.74%. design parametric condition CF/PETG composite established a 41.179 MPa, overall results, it clear variation developed huge favorable impact mechanical characteristics lattice‐structured polymer Highlights Hexagonal Lattice structure incorporation PETG Design properties. performed design‐based Unit percentage contribution strength.
