Abstract
The present invention concerns a composite panel with two cover sheets and between these a core made from a mixture of a granular filler material and a binding agent. The resultant panel meets the requirements governing incombustible building components in various countries, and can therefore be put in the class of incombustible building components. The core material used in known composite panels can be inorganic and incombustible, but all such composite panels known to date suffer from severe disadvantages. To avoid these disadvantages 100 parts by weight of the core material of the panel contains: 85-95 wt % of granular filler material which has an average particle size of over 100 .mu.m and at least 50 wt % Al(OH).sub.3 and 5-15 wt % of a binding agent.
