This paper is focused on the assembly of lightweight sandwich panels built upon patented ‘Opencell’ structure concept. The objective to investigate possibility joining connection members core adjoining skin sheet by plastic deformation at ambient temperature, instead welding or adhesive bonding. methodology draws from earlier developments authors in forming using mortise-and-tenon concept exper...

This paper presents a novel method for rapid fabrication and prototyping of low-density carbon fiber sandwich panel cores based on laser beam cutting (LBC). Using LCB, sandwich panels with lattice core constructions with oblique and vertical strut morphologies were fabricated from two fiber-orientation architectures. Scanning electron microscopy images illustrate the relatively small extent of ...

Many industries use honeycomb composites extensively, including the aerospace, automotive, furniture, packaging, and logistic sectors. A specific type of composite material known as a sandwich is created by joining two stiff but thin skins to lightweight dense core. The strong bending stiffness overall low density are made possible core material's larger thickness despite its typical strength. ...

Aluminum lamination was performed to improve the physical and mechanical properties of several wood-based composite panels. The panels were aluminum-laminated on two faces in a hot press at 689 kPa and 120 °C for 6 min. Four types of wood-based composites were used as cores, and aluminum 3003 alloy sheets were used for face laminations. Polyurethane adhesive ensured bonding strength between the...
