The invention relates to a structured body and a method for its preparation, whereby the structured body is produced of at least one powdery starting material by application of heat and/or pressure, and has several layers, whereby the starting material consists predominantly of thermoplastic basic material, and whereby the density of at least two layers of the structured body differ from each other, and whereby at least one layer of lower density contains hollow microspheres.

A packaging material and assembly are generally disclosed. In use, a multi-layered packaging comprises a first layer of corrugated material, a second layer, a third layer, a fourth layer, and a fifth layer of corrugated material. Additionally, a first bonding material bonds the second layer in between the first layer and the third layer, and a second bonding material bonds the fourth layer in between the third layer and the fifth layer.

Optically clear curable adhesive films that are heat conformable prior to setting include a reactive composition. The curable films are flexible and free-standing, and have a complex viscosity of greater than 100,000 poise (10,000 Pascal seconds) at 25° C. and less than 100 poise (10 Pascal seconds) at 85° C., prior to setting. The set film has an adhesive shear strength of greater than 100 Newtons per square centimeter (N/cm.sup.2) to a glass substrate when measured according to the Shear Adhesion Test Method. The reactive composition includes an ethylenically unsaturated polyester-containing oligomeric composition that is the reaction product of a saturated, amorphous co-polyester polyol and a compound with a terminal polyol-reactive group and a terminal ethylenically unsaturated group, a (meth)acrylate functional material, and at least one initiator.

Methods of producing a multi-ply paper product are provided. The methods comprise applying coagulant and/or hybrid coagulant-flocculant composition to an upper ply substrate disposed adjacent and above a lower ply substrate in an amount such that a portion of the coagulant and/or the hybrid coagulant-flocculant composition passes through the upper ply substrate. Preferably, the lower ply substrate has a greater freeness than the upper ply substrate. The methods of the present disclosure preferably allow for efficient use of RDF chemicals while making use of the innate freeness differences between the upper and lower ply substrates.

A structural member of a vehicle includes a metal body, a first resin layer and a second resin layer. The metal body is made of metal. The first resin layer is provided on the metal body in a layering direction and includes a first thermoplastic resin. The second resin layer is provided on the first resin layer in the layering direction and includes a second thermoplastic resin and carbon fiber.

In a complex of the invention, a resin member made of a resin material including a polyolefin and a metal member are joined together through a primer layer. In addition, the resin member is obtained by molding the resin material by injection, a coexistence layer in which a primer resin material configuring the primer layer and the resin material coexist is formed between the primer layer and the resin member, and a thickness of the coexistence layer is in a range of more than or equal to 5 nm and less than or equal to 50 nm.

A carbon-carbon composite preform including a plurality of layers including carbon fibers or carbon-precursor fibers, the layers include a first exterior layer defining a first major surface, a second exterior layer defining a second major surface, and at least one interior layer disposed between the first exterior layer and the second exterior layer, the at least one interior layer having a peripheral region that forms a portion of an outer surface of the preform. The preform includes needled fibers, where at least some needled fibers extend through two or more layers. The preform has an exterior region and a core region, where the exterior region includes at least the peripheral region of at least one interior layer. The needled fibers define a first needled fiber number density (NFND) in the exterior region and a second greater NFND in at least a portion of the core region.

A structural insulated sheathing including a rigid foam insulation board having a first face, a structural member having a second face, wherein the first face of the foam insulation board is laminated to the second face of the structural member over substantially 100% of the interface between the first face and the second face.

The invention relates to a process for producing a polypropylene composition by sequential polymerization said polypropylene composition having low sealing initiation temperature (SIT) and high melting point (Tm), presenting thus a broad sealing window.

Provided is a hook-and-loop fastener female member including an engaging layer adopting a non-woven fabric, the hook-and-loop fastener female member being excellent in engaging force with a hook-and-loop fastener male member. The hook-and-loop fastener female member of the present invention includes an engaging layer engageable with a male member, in which the engaging layer includes a non-woven fabric of fiber, in which the non-woven fabric in the engaging layer has a density of from 5 kg/m.sup.3 to 110 kg/m.sup.3, and in which the fiber has a diameter of from 15 μm to 60 μm.
