A beam assembly includes a first beam member and a second beam member. The first and second beam members are both flexible when separated from each other. The first and second beam members each include compression and tension elements. The first and second beam members can be joined to form a stiff beam by interleaving the compression elements of the first and second beam members.

The present invention refers to a composite material that comprises carbon fiber or sheet made from polyacrylonitrile (PAN) or lignin being indicated for the manufacture of several articles such as high resistance pressure cylinder. Said material presents several advantages such as, for example, to provide improved screening to the articles that comprise it. The referred composite comprises: a first inner layer of polytetrafluorethylene, covered by a second layer of high-density polyethylene, adhered to a third layer of composite containing carbon fiber or sheet made from polyacrylonitrile (PAN) or lignin immersed in cured epoxy resin from a polymeric matrix and a hardener; and a fourth outer layer of composite, comprising aramid fiber impregnated with a dilating fluid and cured epoxy resin from a polymeric matrix and a hardener.
