A carrier material has a resin layer arranged on a side of the carrier material. The resin layer includes a formaldehyde resin, a polymer selected from a group containing polyacrylates, polyepoxides, polyesters, polyurethanes, and long-chain silanols, and at least one silane-containing compound of general formula (I), R.sub.a SiX.sub.(4-a), and/or the hydrolysis product thereof, where X is H, OH, or a hydrolyzable residue selected from the group comprising halogen, alkoxy, carboxy, amino, monoalkylamino or dialkylamino, aryloxy, acyloxy, alkylcarbonyl; R is a non-hydrolyzable organic residue R selected from the group comprising alkyl, aryl, alkenyl, substituted and unsubstituted alkynyl, cycloalkyl, which can be interrupted by O or NH; and where R can have a functional group Q selected from a group containing a hydroxy, ether, amino, monoalkylamino, dialkylamino, anilino, amide, carboxy, mercapto, alkoxy, aldehyde, alkylcarbonyl, epoxide, alkenyl, alkynyl, acryl, acryloxy, methacryl, methacryloxy, cyano, and isocyano group, and a is 0-3.

A fiber reinforced powder paint provides improved flexural fatigue resistance for composites substrates. Fiber loading in the powder is greater than 40%. Aramid fiber loading in an epoxy based powder paint is exemplified. A composite bow limb coated with the powder paint survives a remarkably greater number of bending cycles before failure when coated with the powder paint.

A sandwich component and method of producing the sandwich component are provided wherein the sandwich component has a first cover layer, a second cover layer, and a core disposed therebetween. In the sandwich component, the cover layers are each formed from an outer layer made of a fiber-reinforced high-melting-point thermoplast material and, fused therewith, an inner layer made of a low-melting-point thermoplast material. The core has outer layers, each of which is formed from a low-melting-point thermoplast material, and an inner structure, which is formed entirely or partially from a high-melting-point thermoplast material. The inner layers of the cover layers were each fused with one of the outer layers of the core.

An implantable medical device includes a first component including a first material, a second component including a second material, and a fiber matrix including a plurality of fibers. The fiber matrix joins the first component to the second component. The fiber matrix includes a first a first portion connected to the first component, and a second portion connected to the second component. The first portion of the fiber matrix is interpenetrated with, and mechanically fixed to, the first material. The first portion of the fiber matrix directly contacts the first material.

The present invention relates to a multilayer composite, comprising at least three superimposed and face-to-face joined plies of fibre composite which are defined relative to one another as two outer plies of fibre composite and at least one inner ply of fibre composite, wherein each of these plies of fibre composite comprises endless fibres unidirectionally aligned within the respective ply and embedded in a polycarbonate-based plastic, wherein the polycarbonate is selected from homopolycarbonate or copolycarbonate, the inner plies of fibre composite have the same orientation and their orientation relative to the outer plies of fibre composite is rotated by 30 to 90 and wherein the outer plies of fibre composite have a lower volume content of fibres based on the total volume of the ply of fibre composite than the at least one inner ply of fibre composite. The invention further provides a process for producing the multilayer composite according to the invention and also provides a housing part which is suitable for use or employment in a housing of an electronic device and is obtainable from the multilayer composite.

A pull-tab sealing member for a container providing a foamed polymer layer positioned within the sealing member for effective heat sealing to the container together with a lower laminate below a tab capable of tearing to provide a tamper evident structure below the tab.

A method of manufacturing a fiber reinforced composite material lid for an utility vault including mixing an unsaturated polyester thermosetting matrix in to a resin paste, compounding the resin paste into a fiber reinforced composite material, maturing the compounded fiber reinforced composite material, cutting the matured compound into a charge pattern, molding the charge pattern in a mold cavity of a heated mold under low pressure to form the lid and cooling and machining the lid. The mold includes a cavity die and a core die having a shear angle for interfacing the core die within the cavity die and a steam pot for heating the cavity die and the core die, wherein the lid is molded between the cavity die and the core die and removed from the mold by a lid ejection mechanism.

Pyrolized organic layers and conductive prepregs made therewith are provided.

A flat lightweight member that is favorable in appearance quality and also excellent in productivity while being excellent in mechanical property at the ends and adhesiveness between a core and a skin includes: skin layers disposed on both surfaces of the flat lightweight member; end reinforcing layers disposed to have contact with both inner surfaces of the skin layers on the both surfaces at the ends of the flat lightweight member; and a core layer disposed in the space surrounded by the skin layers and the end reinforcing layers to have contact with the inner surfaces of the skin layers.

A composite article (30), comprising at least one fibrous layer (12), and at least one thermoplastic epoxy web layer (14) located in direct planar contact with the at least one fibrous layer (12), the at least one thermoplastic epoxy web layer (14) being adapted to substantially phase separate during a molding and/or curing process.
