ABSTRACT:
A process is provided for bending a board in synthetic material filled with more than 20% by weight of alumina trihydrate in a methyl methacrylate matrix: a section of the board is heated so that it can be bent; the section to be bent is bent while holding the convex upper surface of the board such that it does not become elongated. Also provided are a device for implementing such a process, and a bent board obtained by such a process.
