A fiber-reinforced composite material has a fabric base material including laminated obliquely-crossed fabric layers, each of which is configured by weaving first and second reinforced fiber bundles, which obliquely cross each other. In adjacent two of the fabric layers, one of an orientation of the first reinforced fiber bundles and an orientation of the second reinforced fiber bundles in one fabric layer is the same as one of an orientation of the first reinforced fiber bundles and an orientation of the second reinforced fiber bundles of the other fabric layer. A single-orientation layer is placed between the adjacent fabric layers such that an orientation of fiber bundles of the single-orientation layer is the same as an orientation of reinforced fiber bundles having the same orientation as each other in the adjacent fabric layers.

A passivating flexible insulation blanket positionable about a pipe includes an insulation core, an enclosing fabric, and a non-consumable passivator. The insulation core is substantially hydrophobic and includes a microporous material. The enclosing fabric fully encapsulates the insulation core to form a capsule or pouch about the insulation core. The non-consumable passivator is non-consumable such that there is no appreciable change to a mass of the non-consumable passivator after an extended time of activation. The non-consumable passivator is deposited into the insulation core and has a composition soluble in water. The non-consumable passivator includes a leachable component that leaches from the insulation core and is capable of neutralizing acidic components. The leachable component is water soluble and is capable of reacting with a surface of the pipe to form a protective coating on the pipe to aid in inhibiting corrosion formation on the surface of the pipe.

Structurally enhanced preformed layers of multiple rigid unidirectional rods are constructed and arranged for use in fabricating load-bearing support structures and reinforcements in a variety of composite components, e.g. wind turbine blades. Individual preform layers include multiple elongate unidirectional strength elements or rods arranged in a single layer along a longitudinal axis of the preform layer. Individual rods include aligned unidirectional structural fibers embedded within a matrix resin such that the rods have a substantially uniform distribution of fibers and high degree of fiber collimation. The relative straightness of the fibers and fiber collimation provide rods and the preform layers with high rigidity and significant compression strength. A plurality of rods are loosely attached, e.g. knitted, together with a coupling that allows for each rod to be axially displaced, e.g. slideable, relative to another rod.

Provided is a flooring comprising a multilayer structure comprising successively at least one wear layer, a decorative layer and a sublayer, wherein the decorative layer is in the form of a non-woven textile sheet impregnated with a binder and one of the faces of said non-woven textile sheet comprises a decoration printed with ink. The invention also provides a method for obtaining such flooring.

A method of fabricating a laminar composite article, includes steps of spreading a plurality of continuous fiber tows from a spool to form a first ply layer having a substantially consistent layer thickness, applying a binder to the spread plurality of continuous fiber tows, curing the plurality of continuous fiber tows and applied binder at a cure temperature less than a thermal decomposition temperature of the binder, and processing the cured plurality of continuous fiber tows at a post-cure temperature greater than the cure temperature.

The polyurethane composite floor includes a foamed layer and a decorative layer arranged on the foamed layer, the foamed layer comprises an intermediate core material, two braided fibre layers respectively arranged on a top portion and a lower portion of the intermediate core material, the braided fibre layer arranged on the top end of the intermediate core material is defined as an upper braided fibre layer, the braided fibre layer arranged on the lower end of the intermediate core material is defined as a lower braided fibre layer, the intermediate core material defines a plurality of filling gaps, each filling gap is filled with a rigid polyurethane foam. The present disclosure provides the polyurethane composite floor, and the method for manufacturing the polyurethane composite floor, the polyurethane composite floor has the advantages of low cost, strong weather resistance, and wide adaptability, and the polyurethane composite floor may be integrally-formed by a mold, the chemical internal energies of self-reactions of the rubber elastomer layer and the polyurethane foaming material can be used to catalyze and cure mutually, which greatly saves the production energy consumption, and avoids the use of glue, the polyurethane composite floor is much more environmentally friendly and durable, and the processing process is simple.

Composite panel for air cargo containers including a fire resistant, closed cell foam core, a skin attached to at least one surface of the core formed by fire resistant fibers in a matrix resin, wherein the panel will contain an internal fire with temperatures of up to 1500° F. for a period of at least 4 hours.

This disclosure relates to using polyester films on building boards to enable improved surface coatings. The polyester film is preferably applied to a glass mat via an adhesive to form a laminate. This laminate is then bonded to the exterior surface of a gypsum board. The polyester film is advantageous because it allows for exterior surface coatings to be applied. In one embodiment, an exterior acrylic coating is applied to the polyester film. Boards constructed in accordance with this disclosure allow for exterior finishings to be achieved without the need for excessive finishing materials or steps.

A reinforcement sheet has a composite layer including fibres and a polymer A and a coating layer including polymer B, each polymer having at least 65 mol % of a repeat unit of formula:

##STR00001##

wherein for each polymer A and B, t1, and w1 independently represent 0 or 1 and v1 represents 0, 1 or 2. A method of forming the reinforcement sheet is also disclosed, in addition to a method for forming an article comprising a laminate of the reinforcement sheets and the article comprising such a laminate. The repeat unit may be ether-ether-ketone.

Disclosed is an acrylic resin composition that has excellent weather resistance and can be stably produced at high temperatures. Specifically, disclosed is an acrylic resin composition including, with respect to 100 parts by mass of an acrylic resin, from 0.1 to 8 parts by mass of a triazine-based UV absorber including 2-(4,6-diphenyl-1,3,5-triazin-2-yl)-5-[2-(2-ethylhexanoyloxy)ethoxy]phenol, wherein the acrylic resin used is an acrylic resin including at least 80 wt % of methyl methacrylate as a monomer component, and having a glass transition temperature of at least 80° C.
