According to an aspect, a pressure bonding device is configured to bond, to a plate-like first workpiece having a curved surface part, a plurality of plate-like second workpieces smaller than the first workpiece. The pressure bonding device includes: a vacuum chamber; a stage disposed in the vacuum chamber and having a shape extending along a first surface of the curved surface part of the first workpiece so as to fix the first surface on the stage; and a bonding unit configured to deform an elastic diaphragm by internal pressure and pressure-bond one of the second workpieces to a second surface of the first workpiece. A plurality of the bonding units are disposed facing the stage.

In one aspect of the present subject matter, a method of forming a linear panel includes drawing a multi-layer panel material assembly having differing inner and outer material layers along a processing path. The method also includes heating the panel material assembly. In addition, the method includes forming the heated panel material assembly into a desired shape as the assembly is drawn along the processing path. Additionally, in another aspect of the present subject matter, a linear panel includes a body formed from a multi-layer panel material assembly having differing inner and outer material layers.

Stabilizing a textile sheet structure was achieved by forming a plurality of discrete fiber tufts extending from a first face of a fibrous layer of the textile sheet structure, through the fibrous layer and beyond a second face opposite the first face. Each discrete fiber tuft included a plurality discrete fibers. Each discrete fiber tuft was anchored to the first face and the second face of the fibrous layer by joining together the plurality of each discrete fiber tuft at the first face and the second face and bonding the joined plurality of discrete fiber tuft to the first face and the second face.

A flexible balsa wood panel for a rotor blade of a wind turbine, including a plurality of balsa wood modules and a polymer film which is attached to a surface of each balsa wood module to connect the balsa wood modules together is provided. The flexible balsa wood panel has the following advantages. An adhesion area of the polymer film is significantly larger than that of a glass fiber mesh. This in turn reduces the risk of balsa wood modules falling off during handling the flexible balsa wood panel. A polymer film with a high melting temperature relative to a maximum blade curing temperature can be selected in order to avoid curing process induced delaminations. Furthermore, due to the polymer film attached to the first surface, a more uniform adhesion may be achieved compared to a currently used glass fiber mesh.
