Fiberglass Honeycomb Panel is a three-layer composite panel that is made with two layers of fiberglass (FRP / GRP) as top & bottom skins and laminated to a PP honeycomb core or aluminium honeycomb core.

Fiberglass sheet is also called FRP or GRP, meaning it's a glass fiber reinforced plastic. So FRP itself is a composite of fiberglass and resins. And we commonly see fiberglass sheets to be used for aerospace, automotive, marine, and construction industries. In many cases, it has to be installed with some other substrate materials or framing because the FRP sheet itself is not rigid enough and a certain supporting is necessary for many applications
