A method for surface preparation of a composite substrate prior to adhesive bonding. The surface preparation method includes applying a resin-containing peel ply onto a composite substrate, followed by co-curing. The resin-containing peel ply contains a non-removable textile carrier and a removable woven fabric embedded therein. After co-curing, the peel ply is removed from the composite substrate such that the removable woven fabric is removed but the non-removable textile carrier and a film of residual resin remain on the composite substrate, thereby creating a modified, bondable surface on the composite substrate. The composite substrate with the modified surface can be bonded to another composite substrate, whereby the textile carrier remains an integrated part of the final bonded structure.

A foam assembly system is provided. The system is configured to heat a surface of foam. After the heating of the foam, an adhesive is applied, typically a high solids adhesive. The foam is then bonded to another foam surface. It has been found that the pre-heating of the foam before adhesive application greatly enhances the bond strength between the foam and the second foam surface to which it is adhered.

A method for bonding a composite material includes impregnating a first composite material containing reinforcing fibers and a second composite material containing reinforcing fibers with a resin and bonding them together. A plurality of protruding members each including a plurality of protrusions protruding in mutually different directions are placed on a surface of the first composite material, and the second composite material is placed where the protruding members are placed. The protruding members are introduced into the interior of the first composite material and the interior of the second composite material while causing the first composite material and the second composite material to come into contact with each other. The first and second composite material are bonded in a state where the protruding members are introduced therein, by curing the resin with which the first and second composite material are impregnated.

A method to produce a veneered element, the method including applying a first layer on a substrate, applying a second layer on a veneer layer, applying the veneer layer with the second layer applied thereto on the first layer, such that the second layer is facing the first layer, pressing the first layer, the second layer and the veneer layer together to form a veneered element, thereby material originating from the second layer permeates into the veneer layer, and wherein, after pressing, the first layer is visible through a crack, cavity, hole and/or knot of the veneer layer. Also, a veneered element.

A method for producing a composite pane, includes arranging a functional element in a recess of a thermoplastic frame film, arranging the thermoplastic frame film along with the functional element between a first glass pane and a second glass pane to form a layer stack, and subsequent joining of the layer stack by lamination to form a composite pane. The thermoplastic frame film and the functional element have a different thickness and the different thickness is at least partially compensated by at least one thermoplastic compensating film, whose thickness is less than twice as large as the difference between the thicknesses of the thermoplastic frame film and the functional element such that the maximum offset in the layer stack is less than the difference between the thicknesses of the thermoplastic frame film and the functional element.

Various fabric products incorporating exterior hydrostatic barriers and processes for manufacturing such fabric products are provided.

Provided is a laminate having a gel layer on a substrate able to protect the substrate during various types of processing used in industrial production steps prior to curing. The gel layer has excellent heat resistance, softness and flexibility, a low modulus of elasticity, low stress, excellent stress buffering properties, and electronic component retention properties. The gel layer has higher shape retention before curing but changing after curing into a hard layer having excellent release properties. The laminate is easily and readily releasable from the substrate even when the cured layer is localized. Applications thereof are also provided (such as an electronic component manufacturing method). The laminate comprises a laminated reaction-curable silicone gel and a sheet-like member laminated via an adhesive layer on top of the reaction-curable silicone gel.

A method to produce a veneered element, the method including applying a first layer on a substrate, applying a second layer on the first layer, applying a veneer layer on the second layer, pressing the first layer, the second layer and the veneer layer together to form a veneered element, wherein, after pressing, the second layer is transparent or translucent such that the first layer is visible through a crack, cavity, hole and/or knot of the veneer layer. Also, such a veneered element.
