A wood or engineered wood structural panel, such as, but not limited to, OSB (“oriented strand board”) or plywood, that is both fire-resistant and water resistant. The panel is factory-coated with a product that provides fire resistance. The treatment gives it a Fire-Resistant (FR) performance (for use in a one- or two-hour rated assembly). The panel also is overlaid or coated in a factory setting with a weather/water resistive barrier (WRB). The structural panel thus combines a fire-resistant structural sheathing and WRB product in one integrated panel produced at a factory prior for installation at a job site.

A method for bonding composite substrates includes coupling a first co-cure prepreg layer having a first off-set amine to epoxide molar ratio onto a surface of a first composite substrate and coupling a second co-cure prepreg layer having a second off-set amine to epoxide molar ratio onto a surface of a second composite substrate. The first and second composite substrates are cured to the first and second co-cure prepreg layers, respectively, using a first cure cycle (including B-stage and cure temperatures) to form a first and a second co-cure prepreg layer portion. The method further includes coupling the first co-cure prepreg layer portion to the second co-cure prepreg layer portion and applying a second cure cycle to cure the first co-cure prepreg layer portion of the first composite substrate to the second co-cure prepreg layer portion of the second composite substrate to form a monolithic covalently bonded composite structure.

A large number of green veneers for plywood respectively having high water contents and formed in a rectangular shape are vertically laminated to obtain a veneer laminate having a quadrangular prismatic shape. The veneer laminate is located between upper and lower platen members so that two opposite side faces of the veneer laminate vertically form cut face gathering planes. The upper and lower platen members are moved toward each other to apply a pressing force to the veneer laminate. The pressing force applied to the veneer laminate is released or weakened while the water drawn through the cut face gathering planes by the pressing force is dripping downward along the cut face gathering planes of the veneer laminate vertically formed.

A method to produce a panel. The method includes providing a core having a first surface, providing a surface layer including a substantially uncured amino resin, applying an hydrolysable adhesive on the first surface of the core and/or on a surface of the surface layer adapted to face the core, arranging the surface layer on the first surface of the core, pressing the surface layer to the core to form a panel by applying heat and pressure in a press, thereby adhering the surface layer to the core by the hydrolysable adhesive and curing the amino resin of the surface layer. Also such a panel.

Curable prepregs possessing enhanced ability for the removal of gases from within prepregs and between prepreg plies in a prepreg layup prior to and/or during consolidation and curing. Each curable prepreg is a resin-impregnated, woven fabric that has been subjected to a treatment to create an array of openings in at least one major surface. Furthermore, the location of the openings is specific to the weave pattern of the fabric.

Provided is a structural member for electronic devices which uses a material that is flexible and has excellent restoration properties after extension and stress relaxation properties. The structural member for electronic devices has the following properties A and B: (Property A) In a case where predetermined deformation is applied, stress that applies the deformation is relaxed (reduced) with time: and (Property B) In a case where the stress that applies deformation is 0, the deformation rarely remains while a resin composition is recovered. That is, when stress is 0, residual strain substantially becomes 0 (specifically 3% or lower).

A film stack made from compacted green films and capable of being sintered to form a ceramic component with monolithic multi-layer structure is disclosed. The film stack includes a functional layer comprising a green film comprising a functional ceramic and a tension layer comprising a green film comprising a dielectric material. The tension layer is directly adjacent to the functional layer in the multi-layer structure. The multilayer structure also includes a first metallization plane and second metallization plane. The functional layer is between the first metallization plane and the second metallization plane.

A method for producing a Fiber Metal Laminate component of an airplane, using a manipulator system with an end effector and a control, wherein at least one metal layer and at least one unhardened fiber layer are being stacked onto each other in a mould in a stacking sequence, wherein each stacking cycle comprises picking up a metal layer or a fiber layer from a supply stack according to the stacking sequence, transporting the layer to the mould, placement of the layer at a deposition surface in the mould and depositing the so placed layer onto the deposition surface. After being picked up from the supply stack and before being deposited onto the deposition surface the layer to be stacked can be deformed by the end effector as to adapt the form of the layer to the form of the deposition surface.

A laminate of a rubber layer (A) and a fluororesin layer (B) on the rubber layer (A), wherein the rubber layer (A) is a layer made of a rubber composition for vulcanization, the rubber composition for vulcanization contains an unvulcanized rubber (a1); at least one compound (a2) selected from the group consisting of a 1,8-diazabicyclo(5.4.0)undec-7-ene salt, a 1,5-diazabicyclo(4.3.0)-non-5-ene salt, 1,8-diazabicyclo(5.4.0)undec-7-ene, and 1,5-diazabicyclo(4.3.0)-non-5-ene; magnesium oxide (a3); and silica (a4), the amount of the compound (a2) is larger than 1.0 part by mass and not larger than 5.0 parts by mass, for each 100 parts by mass of the unvulcanized rubber (a1), the fluororesin layer (B) is a layer made of a fluoropolymer composition, and the fluoropolymer composition contains a fluoropolymer (b1) having a copolymer unit derived from chlorotrifluoroethylene.

Prepregs having a UV curable resin layer located adjacent to a thermally curable resin layer wherein the UV curable resin layer includes at least one UV cured resin portion and at least one UV uncured resin as well as methods for preparing flexible printed circuit boards using the prepregs.
