A carbon fiber reinforced skateboard is formed of laminated wood layers having identified grain directions. Upper and lower wood layers will have a grain direction parallel to a long axis of the skateboard. The skateboard will have interspersed wood layers with identified grain directions perpendicular to the long axis. Carbon fiber reinforcing material is adhered to interior plies of the skateboard along the long axis. A central portion of the reinforcing material is adhered below a central vertical point of the skateboard between the skateboard trucks. Anterior and posterior portions of the reinforcing material are adhered above the central vertical point and are located around the attachment locations for the skateboard trucks. The reinforcing material is located to provide a strengthened spine for the skateboard. A first concavity is located between the skateboard trucks parallel to the long axis. Second and third concavities are located perpendicular to the long axis.

The present invention relates to a method for producing a multi-layer substrate, said substrate comprising a multifunctional coating, and to the use of the substrate produced by this method.

The present disclosure is directed to peelable, heat-sealable lidding films for containers of diverse polymer compositions storing various products such as foodstuffs and pharmaceuticals. The lidding films disclosed herein can be heat-sealed to crystalline polyester trays (CPET), easily peeled, and contain improved antifogging performance by incorporating a non-migratory antifogging additive into the heat sealable layer of the film without deteriorating seal strengths.

The present invention provides a foam, a laminated foam, and a laminate that are capable of providing good walking comfort and exhibiting excellent vibration-damping properties while being lightweight and are also useful for recycling interlayer films for a laminated glass. The present invention also aims to provide a building material for housing including any of the foam, the laminated foam, and the laminate. Provided is a foam having a plurality of cells, the foam containing a polyvinyl acetal and a plasticizer and having an average aspect ratio (a/b) of cells of 1.1 or greater as calculated by a predetermined method.

There is provided laminated glass with a heat shielding property in which a need to change an intermediate film is reduced even though thicknesses of glass plates are changed. Laminated glass of an embodiment includes: a pair of glass plates; and an intermediate film sandwiched between this pair of glass plates. A total thickness of the pair of glass plates and the intermediate film is 3.6 mm or less. Further, a ratio (A.sub.2/A.sub.1) of an absorbance (A.sub.2) of the intermediate film at the wavelength of 1500 nm to an absorbance (A.sub.1) of the pair of glass plates at a wavelength of 1500 nm is 2.0 or more when plate thicknesses of the pair of glass plates are each set to 2.0 mm. Further, a solar radiation transmittance (Tts) provided by ISO13837 (2008) is 60% or less.

Disclosed is a flexible material including a web of fibers chosen in the group consisting of carbon fibers, glass fibers and aramid fibers, this web of fibers being impregnated on a so-called external face with an impregnation layer produced from a polymer binder and containing at least one plasticizing agent or a mixture of plasticizing agents. A fibrous textile substrate is superimposed on the web of fibers on an internal face of the web opposite the external face.

Liner having an induction heat sealable layer for sealing to a rim of a container, and a pull tab for ease of removal of the liner from the container rim. A folded insert disposed between multilayer upper and lower components, has a heat bondable polyolefin layer that is thermally laminated to polyolefin layers of the upper and lower components, forming a pull tab between the integrated polyolefin layers. The resulting composite resists delamination and can be formed in a single thermal lamination step, avoiding the multiple lamination steps, associated high equipment costs, and complex layer constructions of the prior art.
