Abstract: Honeycomb core materials have attracted wide attention due to their low density, lightweight, high specific strength, high specific stiffness, excellent compressive performance, and good thermal insulation properties. Currently, they have been widely used in various fields such as aerospace, vehicles, ships, construction, and mechanical engineering. In recent years, continuous fiber reinforced composite honeycomb cores with lightweight and excellent mechanical properties have gained attention as replacements for traditional aluminum honeycombs and aramid paper honeycombs. This article provides a comprehensive review of the latest research progress on carbon fiber and glass fiber reinforced composite honeycomb cores. In terms of carbon fiber composite honeycomb cores, different preparation methods such as hot press molding method, vacuum-assisted resin transfer molding method, inter-locking method, 3D printing method, and tailor-folding method are introduced. Regarding glass fiber composite honeycomb cores, the focus is on the research progress in preparation methods. This article reviews the recent advances in the field of continuous fiber reinforced composite honeycomb cores, aiming to provide an indepth overview for beginners in this field.
