“…Nowadays, in aerospace industries, metals are increasingly being replaced by composites, as they are lightweight and exhibit high impact resistance, good thermal insulation, and better fatigue performance 4,5 . Sandwich composites, as compared to conventional composites, have a high strength to weight ratio and high specific stiffness 6,7 . In sandwich panels, a thick lightweight core (such as honeycomb, foam, and wood) is placed between two thin face‐sheets (such as carbon, glass, and Kevlar fabrics) and are then impregnated with polymer matrix 8 .…”

In this study, the fire‐retardant performance of lightweight sandwich composites, with modified epoxy impregnated carbon and glass fabric reinforcements and an aluminum honeycomb core, is investigated. The fire‐retardant performance of the fabricated sandwich composites is improved by treating carbon fiber reinforcements with phosphoric acid, and by impregnating the epoxy matrix with different loadings of ammonium polyphosphate (APP) fire‐retardant additive. The laboratory aging behavior of sandwich composites is also carried out to further investigate the degradation resistance of the panels under extreme conditions. Fire and mechanical properties of epoxy and sandwich panels are investigated using UL‐94, limiting oxygen index (LOI), thermal gravimetric analysis, compression tests, and three‐point bending tests. In the case of sandwich composites, a maximum of 1345 and 45.2 MPa flexural and compression modulus, respectively, are achieved with 10 wt% APP content in epoxy. Maximum 30% and 33% LOI values are achieved with 10% APP content in the epoxy and sandwich panels, respectively.

In several applications reaching from satellite, ships, aircraft, vehicles, railcars, bond construction and much extra, using sandwich constructions have increased rapidly in different fields. The aim of the subsequent paper is to include an overall summary to sandwich construction and explanation of mechanics structural including forms of actuating loads, failure modes found in sandwich panels and standard three-point bending study of sandwich construction.
