Abstract

A method for continuously molding a honeycomb panel having a sandwich structure wherein a plastic composite is bonded to both surfaces of a honeycomb-shaped core member. A long honeycomb sandwich panel is formed by repeating the following steps: PA0 (1) laminating a prepreg to the upper and lower surfaces of a band-like honeycomb core member to form a band-like blank; PA0 (2) feeding the band-like blank between a pair of upper and lower hot plates having a rectangular plane shape; PA0 (3) pressurizing the hot plates to apply pressure and heat to part of the band-like blank for a preset time; and PA0 (4) relieving the pressure exerted in the hot plates and feeding the band-like blank by a distance corresponding to a partial length of the hot plates.
