A method of forming an article is provided. Multi-fiber cellulose strips are interacted with a bonding agent and layered in a plurality of layers, the layered cellulose strips collectively defining opposed major surfaces. A porous sheet member, interacted with a fire-retarding solution, is engaged with one of the major surfaces of the layered cellulose strips, to substantially cover the major surface. The porous sheet member is disposed adjacent to a substantially smooth and uniform surface, and layered cellulose strips and the porous sheet member collectively exposed to an actuating element, configured to actuate the bonding agent to react in a volumetrically-expensive reaction with the fire-retarding solution to facilitate cohesion between the layered cellulose strips and the porous sheet member to form a board member, wherein the porous sheet member conforms to the adjacent surface via the volumetrically-expansive reaction to define a substantially smooth and uniform surface of the board member.

A composite construction, such as, in particular, a composite plate having a sandwich-type construction, has two outer layers which are mutually opposed in parallel and a foam material completely filling the space between the outer layers at least in some regions. The outer layers are interconnected by means of spacers, and the spacers are connected to the outer layers via a cured plastics material.

The present disclosure discloses a laminating device, a laminating method, and a display device. The laminating device is configured to laminate a flexible member to be laminated to a curved receiving member. The laminating device includes a gasbag. The gasbag includes an elastic housing configured for receiving gas medium. The elastic housing includes a carrying portion and a clamping portion which are connected to each other. The carrying portion is configured to carry the flexible member to be laminated. The elastic housing is provided with a plurality of first apertures. When a gas pressure in the elastic housing reaches a first preset pressure, the gas medium is released to outside of the elastic housing through the first apertures. This design can avoid a bad laminating caused by an improper adjustment of laminating pressure.
