A thermoplastic composite structure is produced by consolidating and forming a composite preform to a desired shape. The preform comprises plies of a high melt temperature thermoplastic prepreg that are tacked together by a low melt temperature thermoplastic adhering the plies together in fixed registration.

A composite fabric includes a nonwoven fabric layer having non-bonded areas and a structured film layer discontinuously bonded to the nonwoven fabric layer. The discontinuously bonded nonwoven fabric layer and the structured film layer share an overlapping area with at least one set of coincident bond sites. The discontinuously bonded nonwoven fabric does not have another bonding pattern in the overlapping area distinct from the at least one set of coincident bond sites. A method of forming a composite fabric is also described. The method includes forming a fiber layer including a mat of at least partially unconsolidated fibers, positioning a structured film layer and the fiber layer such that they overlap, and discontinuously bonding the mat into a discontinuously bonded nonwoven fabric while simultaneously bonding the structured film layer to the nonwoven fabric layer. An apparatus for forming a composite fabric is also described.

A method for producing a covered steering wheel for a vehicle. A steering wheel skeleton is overmolded with a matrix material. A covering material is coated on its non-visible side with an activatable material. The coated covering material is applied to the overmolded steering wheel skeleton so that its non-visible side faces the overmolded steering wheel skeleton. Longitudinal edges of the covering material are joined together. The activatable material is activated with creation of an integral connection between the covering material and the matrix material.

A process and system for making a laminated surface covering and the surface covering itself are described. The covering includes several layers bonded to each other. The system performs the process. One example of the process includes passing a first material across a first conveyor, passing a second material across a second conveyor, passing a bonding material across a third conveyor, contacting the first material and the second material to the bonding material, and heating at least one of the first material and the second material. The process also includes introducing the first material, the second material, and the bonding material into a pressure zone such that the bonding material is introduced between a bottom surface of the first material and a top surface of the second material. The process applies pressure to bond the first material and second material together via the bonding material to produce a laminated material.

An imide resin composition including a terminal-modified imide oligomer of General Formula (1) and a thermoplastic aromatic polyimide of General Formula (2). (In Formula (1), either R.sub.1 or R.sub.2 shows a phenyl group and the other shows a hydrogen atom; R.sub.3 and R.sub.4 show a divalent residue of aromatic diamine; R.sub.5 and R.sub.6 show a tetravalent residue of aromatic tetracarboxylic acid; m and n satisfy relationships of m1, n0, 1m+n20, and 0.05m/(m+n)1; and an arrangement of repeating units may be either a block or random.) (In Formula (2), R.sub.1 and R.sub.2 show a divalent residue of aromatic diamine; R.sub.3 shows a tetravalent residue of aromatic tetracarboxylic acid; m and n satisfy relationships of m1 and n0, and an arrangement of repeating units may be either a block or random).

The invention comprises a method. The method comprises applying a quantity of an aqueous dispersion of thermoplastic polymer particles to a primary backing and loop backs of a tufted carpet or a tufted synthetic turf, wherein the thermoplastic particles have an average particle size less than 1,000 microns. The method also comprises heating the aqueous dispersion to a temperature sufficient to remove water therefrom, and heating the thermoplastic particles on the primary backing and loop backs to a temperature at or above the melting temperature of the thermoplastic particles. The method further comprises allowing the heated thermoplastic polymer particles to cool below their melting temperature whereby the loop backs are adhered to the primary backing.

An object of the present invention is to provide an air filter medium which includes heat-expandable particles that, even when contained in a small amount, impart excellent flame retardancy to the air filter medium and which has excellent flame retardancy and a low pressure loss. The present invention provides an air filter medium including: a plurality of stacked fibrous sheets; and heat-expandable particles and a binder disposed in at least one of interlaminar spaces between adjacent layers of the fibrous sheets.

Provided is a pre-applied waterproofing membrane having a waterproofing adhesive layer and an outer particle layer comprising synthetic polymer granules to protect the adhesive layer and to facilitate detailing at membrane-to-membrane overlaps. In preferred embodiments, the synthetic polymer granules are made from polymers selected from the group consisting of polyvinyl acetate, acrylic, and styrene butadiene copolymers or polymers. Most preferably, the synthetic polymer granules have round or spherical shapes that help to facilitate detailing at the building or installation site, such as sealing at membrane overlaps, and sealing around pipes or other details. Alternatively, the membranes may be made having side edges which are free of synthetic polymer granules, whereby a removable release liner strip can be used to prevent adhesive from sticking to the back of the membrane when the membrane is rolled up on itself for shipment.

A packaging method and a display device are disclosed. The packaging method includes: packaging a display element on a substrate having the display element disposed thereon to form a package covering the display element, wherein a first substance is disposed on at least a part of the substrate inside the package, the first substance including thermite; and initiating the first substance to obtain a second substance including a product of the thermite reaction.
