A machine and method are presented for producing interlaced composite components. The method includes: depositing a first one or more warp filaments onto a deposition surface in a first linear direction, inserting, on top of the first one or more warp filaments, a first one or more weft filaments in a second linear direction, where the second direction is in the same plane as the first one or more warp filaments but is not parallel to the direction of the first one or more warp filaments, depositing, on top of the one or more first weft filaments, one or more second warp filaments in first linear direction, where the second one or more warp filaments are not collinear with the first one of more warp filaments, and inserting, on top of the second one or more warp filaments, a second one or more weft filaments in the second direction.

A method of manufacturing a plurality of reinforcing element preforms, involving the steps of: positioning reinforcing elements on the external surface of a die; assembling the reinforcing elements thus positioned with one another so as to form a textile sleeve with a longitudinal axis and surrounding the die; moving the sleeve longitudinally toward a multi-cavity mandrel having an elongate overall shape, the multi-cavity mandrel having on its external surface a plurality of longitudinal cavities which are distributed, when viewed in cross section, around the periphery of the external surface; forming the sleeve on the plurality of peripheral cavities so that the sleeve conforms to the shape of the multi-cavity mandrel and thus adopts the shape of a set of reinforcing element preforms.

A fireproof, translucent, flexible coated fabric composite material for use in fire curtains. The composite material meets or exceeds regulatory requirements in terms of fire endurance and allows transmissivity of necessary amounts of light. The process of the present disclosure combines a silica fabric with a special refractory index controlled resin. This unique combination of materials can transform an opaque high temperature fabric into a translucent, and even transparent, composite which as the ability to resist high temperature, flame and smoke penetration that fills a needed gap in technology between visibility and fire resistance in the field of fire and smoke curtains used in civil construction.

An impact absorber absorbs impact energy when receiving an impact load. The impact absorber includes a fibrous structure. The fibrous structure includes a tube of which a center axis extends in a direction in which the impact load is applied and a rib that connects opposing inner surfaces of the tube. The fibrous structure is impregnated with a matrix resin. The direction in which the impact load is applied is referred to as an X direction, and a direction in which the rib connects the opposing inner surfaces of the tube is referred to as a Y direction. The tube includes a fiber layer including load direction yarns extending in the X direction and intersecting direction yarns intersecting the load direction yarns. The rib includes yarns extending only in a direction orthogonal to the X direction.

An energy-absorbing member includes a fiber structure. The fiber structure includes a first end face configured to first receive a load and a second end face opposite to the first end face in the direction that the load is applied. The fiber structure includes a shape retention section including the first end face, a main section that includes the second end face and hinders propagation of breakage of the fiber structure, and a trigger section that is located between the shape retention section and the main section and serves as a starting point of breakage when receiving an impact load. The shape retention section and the main section each have a woven structure that allows the shape retention section and the main section to have a higher interlayer bonding strength than the trigger section.

Glass-fiber mats for lead-acid batteries are described. The glass-fiber mats may include a plurality of glass fibers held together with a binder. The binder may be made from a binder composition that includes (i) an acid resistant polymer, and (ii) a hydrophilic agent. The hydrophilic agent increases the wettability of the glass-fiber mat such that the glass-fiber mat forms a contact angle with water or aqueous sulfuric acid solution of 70° or less. Also described are methods of making the glass-fiber mats that include applying a binder composition to the glass fibers, and including a hydrophilic agent in the glass fiber mat that increases the wettability of the mat. The hydrophilic agent may be added to the binder composition, applied to the glass-fiber mat, or both.

The present invention contemplates a method for forming a reformable epoxy resin material into a fiber format and: (i) weaving the reformable epoxy resin material (10) with a reinforcing fiber (12) to form a woven material; (ii) stitching a secondary material (14) with reformable epoxy resin material; and optionally (iii) forming a web or mesh with the reformable epoxy resin material.

A method for producing a fiber preform or semi-finished textile product comprises providing a fiber preform or semi-finished textile product comprising at least one thermoplastic fiber. The thermoplastic fiber has a core constructed of a first material, a shell constructed of a second material positioned to surround the core, and magnetic particles that are one of mainly arranged in the shell, almost exclusively arranged in the shell, and exclusively arranged in the shell. Continually adding the fiber preform or semi-finished textile product with simultaneous heating thereof in continuous passing through or passing by a magnetic induction heating device or the same by way of a relative movement. Fixing the fiber preform or semi-finished textile product by allowing the fiber preform or semi-finished textile product to rigidify.

A yarn for reinforcing composite material includes carbon nanotubes. The yarn has also been treated to promote interaction with a resinous matrix.

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.
