METHOD AND APPARATUS WITH RELIEF DRUM FOR PRODUCING A CORE FOR A COMPOSITE STRUCTURAL PANEL |
摘要 |
<p>The invention is pertaining to the field of the methods of production of corrugated constructions with a folded structure used in the capacity of a filler of multilayered panels. A method for producing a core for a composite structural panel, said method comprising the following steps: feeding prepreg in the form of sheet material (1) to a smooth shaping surface formed by a casing (3) of a substantially cylindrical shape, said casing provided with a plurality of similar flat rigid plates arranged in the form of parallelograms jointly coupled at their sides; providing adhesion of said sheet material (1) to the shaping surface; pressing said sheet material against said shaping surface; deforming the shaping surface by mutual movement of said flat rigid plates in the casing (3) together with turning simultaneously said relief drum (2) around its axis; and removing the molded core. The subject-matters of the invention include also an apparatus for producing a core for a composite structural panel as well as a relief drum included into this apparatus and comprising said shaping surface.</p> |
