A method of manufacturing composite laminate panel sub-elements (34) for subsequent assembling into a modular assembly structure (37), comprises the preprocessing steps of casting an elongate composite laminate sheet panel (18) having opposite first and second fiber-reinforced plastic face skins (19,21) sandwiching a core (35), a free first elongate edge (22) and an opposite second elongate free edge (24), demolding the elongate composite laminate sheet panel (18), cutting the demolded elongate composite laminate sheet panel (18) into (n) shorter sections (Sn), thereby providing sections (Sn) with at least one free cut edge (26; 32), a free first edge (22) having the same profile as the free first elongate edge, and a free second edge (22) parallel to the free first edge and having the same profile as the free second elongate edge, and machining at least a first coupling profile (27) along the at least one free cut edge (26; 32).

In one embodiment, a multiwall sheet can comprise: a first wall; a second wall; an intermediate wall disposed between the first wall and the second wall; a first set of ribs disposed between the first wall and the intermediate wall; a second set of ribs disposed between the second wall and the intermediate wall; a cavity disposed between adjacent ribs; wherein the multiwall sheet is configured to expand and/or collapse when a mechanical force (preferably shear force) is applied to the intermediate wall. Preferably the multiwall sheet has a flexural rigidity of greater than or equal to 10 N/mm.

An apparatus for forming blanks from fibrous material is disclosed. The apparatus includes a die having a porous body with a plurality of perforations extending there through, the plurality of perforations having varying sizes and being layered from a top surface to a bottom surface of the porous body. A smooth molding surface is provided on the top surface to hold the fibrous material and allow water to drain from the fibrous material through the plurality of perforations.

There is provided a method for repairing or reinforcing a structure. The method includes the steps of: providing an adhesive sheet comprising an adhesive layer comprising at least a curable resin composition whose curing is promoted by irradiation with ionizing radiation and a curing aid which generates a basic substance by irradiation with ionizing radiation; attaching the adhesive sheet to a surface of the structure; and curing the adhesive layer of the adhesive sheet in a state where the adhesive layer is exposed.

The present invention relates to a lightweight sound-absorbing and fire-resistant insulation panel including: a binder; expanded graphite; and swelling clays, and the swelling clays are formed of honeycomb-shaped layered clays containing water molecules in interlayers and have particle sizes in the range of 50 to 200 m. Further, the expanded graphite is present in an amount of from 10 to 100 parts by weight per 100 parts by weight of the swelling clays. According to the present invention, the insulation panel is made of the expanded graphite and the honeycomb-shaped swelling clays, thus providing excellent lightweightness, sound absorption, insulation, fire resistance and flame retardancy, and further, the insulation panel is manufactured without having any sintering, thus providing simple manufacturing processes and lowering production costs.

The present disclosure provides various aspects for mobile and automated processing utilizing additive manufacturing. The present disclosure includes methods for the utilization of mobile and automated processing apparatus. In some examples, the mobile additive manufacturing apparatus may perform surface treatments that alter the topography of an existing surface. Other examples may involve the processing of dimensionally large layers which may be joined together to create large pieces with three dimensional shape.

The present invention relates to the use of sacrificial agents to counteract the deleterious impact of gypsum contaminants on the effectiveness of certain stucco additives, particularly, water reducing agents and foaming agents, in a stucco slurry used to make gypsum wallboard.

Described in detail herein is a system for fabricating contoured divider walls using a 3D printer. The system includes a vehicle trailer that has a storage volume. The storage volume is configured to store pallets. Sensors are configured to identify physical attributes associated with the storage volume and each of the pallets. The system can further include a 3D printing device and a computing system coupled to the sensors and the 3D printing device. The computing system is configured to receive the physical attributes of the storage volume and each of the pallets, to divide the pallets into multiple sets of pallets based on position of each of the pallets in the storage volume, to determine a contour shape of each set of pallets in the multiple sets of pallets, and to transmit a first set of instructions instructing the 3D printing device to fabricate one or more divider walls for a set of pallets.

A method for preparing a construction board, the method comprising (i) providing a non-woven mat having a coating layer disposed on a planar surface thereof, where the coating layer includes an inorganic filler dispersed within a polymeric matrix; (ii) contacting an A-side stream of reactants including an isocyanate compound with a B-side stream of reactants including an isocyanate-reactive compound to prepare a developing foam; and (iii) depositing the developing foam on to said coating of said non-woven mat.
