Illustrated and described are a method and a device for laminating a profiled fibre moulding with a thermoplastic film. The film is laminated onto a surface of the fibre moulding to be coated by heat and differential pressure. To improve the lamination of the fibre moulding and to achieve uniform lamination thicknesses over the entire fibre moulding, the method includes the following steps: fixing at least an edge of the fed film to a base plate, heating the film, deforming the film via a moulding tool, feeding the fibre moulding, joining the fibre moulding to the pre-formed film, and removing the laminated fibre moulding.

Disclosed are a laminate having a laminated structure of five or more layers wherein each layer is a resin impregnated fiber reinforced composition layer in which fibers are oriented unidirectionally, the resin in the resin impregnated fiber reinforced composition layer is an olefin-based polymer having the melting point or the glass-transition temperature of 50 to 300 C., and the shape of the laminate can be easily controlled by melt press molding; and a tape winding pipe excellent in balance between bending rigidity and compressive rigidity.

The present invention relates to a multilayer composition comprising a surface layer comprising a thermoplastic polymer A and a substrate layer comprising a polymeric composite material based thermoplastic (meth)acrylic matrix and a fibrous material as reinforcement. The multilayer composition is suitable for mechanical or structured parts or articles with a decorative surface aspect The present invention concerns also a manufacturing process for multilayer mechanical or structured parts or articles and three-dimensional mechanical or structured parts.

A thermoplastic pipe and a method for producing it are described. The thermoplastic pipe includes a hollow inner liner layer, a semi-consolidated core comprising commingled fibers, and a shrink wrap outer layer. The commingled fibers comprise at least one thermoplastic fiber and at least one reinforcing fiber. The semi-consolidated core layer comprises a thermoplastic polymer matrix that is organized along the at least one reinforcing fiber. The method includes winding commingled fibers over the hollow inner liner layer at a designated angle to produce a core layer, covering the core layer in a heat shrinkable wrap, and heating to produce a semi-consolidated core layer. The semi-consolidated core layer comprises a thermoplastic polymer matrix that is organized along the at least one reinforcing fiber.

A thermoplastic pipe and a method for producing a thermoplastic pipe are provided. The thermoplastic pipe includes a liner layer, a semi-consolidated core layer comprising a prepreg polymeric fabric layer, and a shrink wrap outer layer. The semi-consolidated core layer comprises a thermoplastic polymer matrix that is randomly distributed across the fabric. The method includes producing a hollow inner liner layer, winding a prepreg comprising a polymeric powder scattered on a fabric over the hollow inner liner layer to produce a core layer, covering the core layer in a heat shrinkable wrap, and heating to produce a semi-consolidated core layer. The semi-consolidated core layer comprises a thermoplastic polymer matrix that is randomly distributed across the fabric.

An elastic sheet for an absorbent article includes a first fibrous layer disposed on a first surface of the elastic sheet, a second fibrous layer disposed on a second surface of the elastic sheet opposite to the first surface, and contractible elastic members secured between the first fibrous layer and the second fibrous layer. The first fibrous layer and the second fibrous layer each include continuous fibers of thermoplastic and gathers formed between adjacent ones of the elastic members. The gathers are disposed in an intersecting direction intersecting with a direction in which the elastic members extend. An average flexural rigidity value of the first fibrous layer and the second fibrous layer in accordance with a KES method is 0.003510.sup.4 to 0.02210.sup.4 (N.Math.m.sup.2/m). A thickness under a compression load to the gathers in accordance with the KES method is 0.22 to 1.5 mm.

A composite panel includes a backing substrate and a first plurality of fiber tows. The first plurality of fiber tows is stitched to a first surface of the backing substrate in a predetermined pattern to form a fiber reinforced insert. A first polymer layer encapsulates the first surface of the backing substrate and the first plurality of fiber tows.

The present disclosure provides adhesive articles that can be removed from surfaces without damage by having reduced or eliminated contribution of a core backing to peel force generated by the adhesive during removal. In some instances, this can be accomplished by a core that loses structural integrity in a direction normal to a plane defined by a major surface. In other instances, the contribution is reduced by compromising the interface between the core and a peelable adhesive layer.

One or more nanofiber yarns can be placed in contact with one or more nanofiber sheets. The nanofiber yarns, which include single-ply and multi-ply nanofiber yarns, provide added mechanical stability to a nanofiber sheet that decreases the likelihood of a nanofiber sheet wrinkling, folding, or otherwise becoming stuck to itself. Furthermore, the nanofiber yarns integrated with the nanofiber sheet can also act as a mechanism to prevent the propagation of tears through the nanofiber sheet. In some cases, an infiltrating material can be infiltrated into interstitial spaces defined by the nanofibers within both the nanofiber yarns and the nanofiber sheets. The infiltrating material can then form a continuous network throughout the nanofiber yarns and the nanofiber sheet.
