A FRP tubular body includes a tubular fiber structure formed by winding a reinforced fiber sheet made of fabric. The reinforced fiber sheet includes first reinforced fiber bundles arranged such that a yarn main axis direction extends in a circumferential direction of the fiber structure and second reinforced fiber bundles arranged such that a yarn main axis direction extends in an axial direction of the fiber structure. The reinforced fiber sheet includes a starting end, a finishing end, and a general portion located between the starting end and the finishing end. The general portion includes the first reinforced fiber bundles and the second reinforced fiber bundles. At least one of the starting end or the finishing end is a decreased portion that is smaller than the general portion in an amount of reinforced fibers per unit length in the circumferential direction of the fiber structure.

The present invention relates to a thermally-resistant woven fabric and/or multiple ply fabric sheet for use as single or outer layer of protective garments, of the type comprising an inside fabric layer and an outside fabric layer joined together by an array of connecting lines. The woven fabric and/or multiple ply fabric sheet comprise yarns, wherein said yarn comprises i) meta-aramid ii) from about 5 to 10 weight % of polyamide and iii) at least 2 weight % of antistatic fibers, the weight % being based on the total weight of the yarn.

The invention relates to a blade (3) of a fan (1) of a turbomachine having a structure made of a composite material comprising a fibrous reinforcement (5) obtained by three-dimensional weaving and a matrix in which the fibrous reinforcement (5) is embedded, the fibrous reinforcement (5) comprising first strands (9) having a predetermined elongation at break, a portion of the fibrous reinforcement (5) further comprising second strands (10) having an elongation at break higher than that of the first strands (9).

The invention relates to a heat sink (1) having a main body (2) and a plurality of carbon-nanostructure-based fibres (CNB, 3), more particularly carbon nano tubes (CNT, 4) or graphene fibres, of which at least some are attached to the main body (2). According to the invention, the fibres (3, 4), by adhering to or supporting one another, form a volume structure (12), more particularly in the manner of cotton wool, felt or a spun yarn, or the fibres (3, 4) form loops (6) or a three-dimensional woven fabric.

A method of manufacturing a fabric structure for use in manufacturing a composite aircraft blade. The method comprises: combining yarns including both reinforcing material filaments and a matrix material with yarns of reinforcing material filaments and/or yarns including at least one filament of matrix material; or by combining yarns of reinforcing material filaments with yarns including at least one filament of matrix material; or by combining yarns each comprising both reinforcing material filaments and matrix material. Combining may comprise weaving, knitting or braiding. The matrix material may be a thermoplastic.

A sole includes a bottom layer and a carbon fiber layer. The bottom layer has at least two engaging portions. The carbon fiber layer is penetrated by at least two fitting holes. The at least two engaging portions are engaged with the at least two fitting holes, respectively. The diameter of the at least two fitting holes, which is close to the bottom layer, is less than the diameter of the at least two fitting holes closed to a upside surface of the carbon fiber layer. The at least two engaging portions undergo an injection process so as to be coupled to the at least two fitting holes, respectively, thereby reducing greatly the chance of injury which might otherwise happen to users as a result of separation of the bottom layer and the carbon fiber layer of the sole while the users are running quickly.

A safety airbag mesh, which includes a fiber layer. The fiber layer includes a warp fiber unit that extends warpwise and a weft fiber unit that extends weftwise, characterized in that the warp fiber unit includes a plurality of first fibers and second fibers arranged weftwise. The first fibers warpwise cover a buffer area and a support area, and the first fibers in the buffer area take on nonlinear formation, and extend longer than the second fibers in the area.
