An article manufactured in a mould and which comprises a structural composite of plastics layers, the article having a wall defining an internal space for holding contents therein; wherein, the wall is formed from at least two layers of plastics materials; wherein a first of said layers comprises a thermoplastics material and at least a second layer comprises a thermosetting resin and a fibrous layer.

An adhesive tape substrate production method disclosed in the present description includes the steps of decreasing the amount of a sizing agent contained in a glass cloth by heat; impregnating the glass cloth for which the amount of the sizing agent has been decreased with a dispersion of a fluorine resin; and heating the impregnated glass cloth to a temperature equal to or higher than a melting point of the fluorine resin. Thus, an adhesive tape substrate including the glass cloth impregnated with the fluorine resin is obtained. This method are more productive of adhesive tape substrates and adhesive tapes than conventional methods. In addition, adhesive tape substrates and adhesive tapes for which the occurrence of defects in appearance are reduced can be produced.

Embodiments of the present invention replace relatively bulky nonwoven thermal insulating materials used in thermal liners with thin, lightweight, flexible films that maintain or improve TPP performance while reducing the thickness, and enhancing the flexibility, of the thermal liner so as to increase wearer comfort. Moreover, the films incorporated into the thermal liners can be both air and vapor permeable such that the TPP performance is not realized at the expense of THL performance. Rather, the THL performance of garments incorporating embodiments of thermal liners contemplated herein is comparable toif not improved overgarments formed with traditional thermal liners.

A method of shortening cycle time required to compression mold shingle or tile is provided, wherein carrier plates are comprised of a surface material and a base, and receive a thermoplastic material, thereon. The roofing material is applied to the carrier plate and the carrier plate is subjected to induction heating, by which its surface material has its temperature raised, without substantially raising the temperature of the carrier plate base, such that the thermoplastic material applied thereto is kept heated in the compression mold. Cooling of the thermoplastic material is by heat transfer from the carrier plate surface material to the carrier plate base, and with both materials having good heat conduction capability. The carrier plate surface material has a high receptivity to being heated by induction heating relative the carrier plate base. The carrier plates are serially delivered through the process, to the compression mold.
