The disclosure provides an improved resin film product is comprised of a partially cured b-staged resin film that has a thickness in the range of 1 mils to about 10 mils and that is disposed between two protective layers, as well as methods for their manufacture and use in the production of layups used to manufacture printed circuit boards.

A breathable multilayer spun bonded polypropylene membrane having a coated pressure sensitive adhesive capable of allowing air and moisture vapor to pass through it. The adhesive is formed of a copolymer comprising a backbone of n-butyl acrylate, 2-ethylhexyl acrylate, and vinyl acetate which is mixed with a surfactant and emulsified to produce bubbles which form pores when the copolymer is set with about 80% to about 90% of the pore sizes ranging from about 200 microns to about 300 microns and a pore density in the cured pressure sensitive adhesive ranging from about 4200 per inch.sup.2 to about 4600 per inch.sup.2, said pores being uniformly distributed to form a flow path through adhesive.

The present invention describes a prepreg for the manufacture of fibre reinforced resin matrix composite materials, the prepreg comprising: a surface film comprising a thermosetting resin and a particulate filler material dispersed therein, and a fibrous layer on which the surface film is disposed, the fibrous layer comprising a plurality of non-woven carbon fibres which are substantially randomly oriented, wherein the fibrous layer has interstices between the carbon fibres dimensioned for absorbing at least a portion of the thermosetting resin during a resin infusion step and filtering at least a portion of the particulate filler material in the surface film to remain in the surface film during the resin infusion step.

A metal composite including an oxidized base metal and a fibrous composite material coupled by a self-assembled monolayer and adhesive is described. Additionally, a method of constructing a metal composite is described, wherein the method includes oxidizing a metal, depositing a self-assembled monolayer, and adhering a fibrous composite to the monolayer.

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.

The invention relates to flexible PCM sheet materials having a high latent thermal energy storage density for the purpose of heat management. The flexible PCM sheet material includes a flexible supporting structure and phase-change-material elements arranged thereon separately in a specific geometry. The phase-change-material elements are geometrically defined structures composed of polymer-bound phase-change material. The flexible PCM sheet materials are characterized by a high latent heat storage capacity and optimized thermal conductivity, are dimensionally stable even in the event of temperature changes and after phase transitions, can be rolled, folded, wound, or cut to size without problems, and can be transported, stored, processed, or used in a single layer or in multiple layers.
