The present invention relates to methods for forming a composite product having a patterned surface. A substrate including a porous structure (136), a sheet-form material (134) and a patterned sheet (131) are pressed together to form the composite product. In preferred examples, the patterned sheet is permeable to curable material in the sheet-form material.

The present invention relates to multi-layered composite structures and to methods for the preparation thereof. The present multi-layered composite structures are light weight and capable of high load bearing making the present multi-layered composite structures especially suitable to be used as load bearing structures in, for example, automotive. Specifically, the present invention relates to methods comprising the steps of a) providing a mould for said multi-layered composite structure; b) layering said mould with two or more layers forming the outer surface of said multi-layered composite; c) filling said layered mould with a mixture comprised of non-expanded heat-expandable microspheres and closing said mould; and d) subjecting said closed mould to a temperature of 80° C. to 140° C. during 1 to 230 minutes thereby providing a relative pressure in said closed mould of 0.1 to 20 bar through expansion of said heat-expandable microspheres thereby forming a multi-layered composite structure in said mould with a foam enforced inner core and a multi-layered outer surface; and e) separating the multi-layered composite structure from said mould.

Enclosure parts for portable information handling systems may be made by heat pressing material layers together. The material layers may include outer fiber-reinforced thermoplastic layers and a core thermoplastic layer comprising a plurality of thermoplastic film layers. The core thermoplastic layer may be die cut to create voids that reduce weight of the enclosure part. A finishing layer may be added, along with attachment features.

The present invention provides a new member having a low refractive index as a substitute for an air layer, for example. The laminated film roll of the present invention includes a long laminated film roll including: an ultra-low refractive index layer having a refractive index of 1.20 or less; and a resin film, wherein the ultra-low refractive index layer is stacked on the resin film. The method of forming the long laminated film roll of the present invention includes steps of: preparing a liquid containing microporous particles; coating a resin film with the liquid; and drying the liquid applied on the resin film, for example.
