The invention relates to a pre-impregnated fibre-reinforced composite material in laminar form, obtained impregnating a fibrous mass with a polymeric binder composition and intended to be subjected to successive forming and complete curing operations to produce a fibre-reinforced composite material. The polymeric binder composition comprises one or more resins chosen in the group consisting of siloxane resins and silsesquioxane resins, and can optionally comprise one or more organic resins. The polymeric binder composition appears as a liquid with viscosity between 55000 and 10000 mPas at temperatures between 50° C. and 70° C. The polymeric binder composition forms a polymeric binder matrix, not cross-linked or only partially cross-linked, that fills the interstices of the fibrous mass. The invention also relates to a method for making said pre-impregnated fibre-reinforced composite material in laminar form. The invention also relates to a manufactured article obtained by hot forming and complete curing of the aforesaid pre-impregnated fibre-reinforced composite material, as well as a method for making said manufactured article.

A method comprising providing a polymeric substrate having a melting point of from about 130° C. to about 190° C., and locating a material layer onto the substrate, wherein the material layer comprises one or more polymeric materials that liquefy upon exposure to temperatures of at least about 100° C., to blend with a softened portion of the polymeric substrate. Upon exposure of one or more of the substrate and the material layer to a stimulus, the temperature is increased in a predetermined temperature zone of one or more of the substrate and material layer to cause blending of the one or more polymeric materials of the material layer with the softened portion of the polymeric substrate.

The present disclosure is directed to a web control guide for an inflation and sealing assembly of a protective packaging formation device for inflating a web material into a chain of inflated cushions. The web control guide is positioned along a material path at a transverse spacing from a first compression element and constrains a first thickness of the material path measured normal to the longitudinal and transverse directions of the material path. The transverse spacing and constrained thickness dimension are sufficiently small to prevent transverse movement of the flexible material towards the first compression element to avoid excessive heating of the web material outside a sealing zone.

Embodiments disclosed herein include multilayer films having a cling layer, a core layer, and a release layer, wherein the cling layer comprises a propylene interpolymer and the core layer comprises a core layer polyethylene composition.

A dental appliance for positioning a patient's teeth includes a removable orthodontic tooth positioning appliance having teeth receiving cavities shaped to directly receive at least some of the patient's teeth and apply a resilient positioning force to the patient's teeth. The appliance includes a hard polymer layer having a hard polymer layer elastic modulus disposed between a first soft polymer layer having a first soft polymer layer elastic modulus and a second soft polymer layer having a second soft polymer layer elastic modulus. The hard polymer layer elastic modulus is greater than each of the first soft polymer layer elastic modulus and the second soft polymer layer elastic modulus. At least one of the first soft polymer layer and the second soft polymer layer has a flexural modulus of greater than about 35,000 psi.

The present invention relates to the production of cellulose from coffee or cocoa husks. The cellulose extracted can be used to produce paper, card stock, and cardboard. In addition, a composite material also comprising a material that allows the release of aromas is manufactured using said cellulose. Said material is used to manufacture a laminated product for use in primary, secondary and tertiary packaging applications. Said type of article allows printing on the outer surface thereof, is biodegradable and biocompatible.

An improved protected graphics assembly according to the invention comprises the following sequential layers: optionally, at least one adhesive layer; at least one graphics layer; and at least one outwardly exposed polymer layer that is essentially free of low surface energy materials and has a gloss value of greater than 90 when tested according to ASTM D2457-03 at a 60-degree angle. The assembly is beneficially applied to a variety of articles and used in a variety of related methods. In an exemplary embodiment, a race car comprises a protected graphics assembly that comprises: optionally, at least one adhesive layer; at least one outwardly exposed polymer layer that is essentially free of low surface energy materials; and at least one graphics layer substantially protected from exterior exposure by the polymer layer.

A patient securing overlay is provided that includes a sheet of fabric for supporting a patient's torso on a surgical table. The sheet of fabric has an upper surface configured to face the patient and a lower surface configured to face a surgical table mattress or underbody support. The sheet of fabric includes friction enhancing elements applied to at least a portion of the upper surface thereof. The sheet of fabric can include an extension at a foot end of the sheet of fabric that provides material to be tucked under a foot end of the surgical table mattress or underbody support for securing the foot end of the sheet of fabric to the surgical table mattress or underbody support. The extension can include one or more friction enhancing elements.

One aspect of the invention provides a system including: a length of energy-dissipative tubing; a first sealing device coupled to a first end of the length of energy-dissipative tubing; and a second sealing device coupled to a second end of the length of energy-dissipative tubing. Exposure to one or more selected from the group consisting of: fault currents or lightning strikes at an exposure point along the length of energy-dissipative tubing will produce arcs at the exposure point and at least one of the first end and the second end.

Disclosed is a bonded assembly comprising at least: a first substrate, a second substrate, an intermediate deformation layer secured to the first substrate, the intermediate deformation layer comprising a material in which cavities are provided so that the intermediate deformation layer has a stiffness which is variable along a direction parallel to the intermediate deformation layer, an adhesive between the intermediate layer and the second substrate.
