A seat rail installed on a vehicle body of a motorcycle. The seat rail includes a lateral member located on a lateral side in a width direction of the vehicle body, the lateral member has a laminated structure in which a sheet material including one layer made of a fiber reinforced resin or a plurality of layers made of a fiber reinforced resin and laminated to each other is folded back and doubly overlapped, and a folded edge part formed by folding back the sheet material is located at a lower edge part of the lateral member. The present invention also relates to a method of manufacturing such a seat rail.

Textile compositions comprising at least one filamentous fungus are disclosed, as are methods for making and using such textile compositions. Embodiments of the textile compositions generally include at least one of a plasticizer, a polymer, and a crosslinker, in addition to the filamentous fungus. The disclosed textile compositions are particularly useful as analogs or substitutes for conventional textile compositions, including but not limited to leather.

This fiber-reinforced resin molded article has: a sheet molding compound layer; a continuous fiber reinforcing material layer; and a harrier layer, wherein the barrier layer is interposed between the sheet molding compound layer and the continuous fiber reinforcing material layer.

A composite material blank comprising an elongate blank body extending between a first end face and a second end face; said blank body extending in a longitudinal direction, parallel to a longitudinal axis thereof, and having four peripheral sides; each said first and second end face having edges which define a trapezoid shape; wherein the peripheral sides of said blank body connect the edges of said first end face with the edges of said second end face; and wherein said first trapezoid end face is inverted in relation to said second trapezoid end face. A method of manufacturing a composite blank, and a wind turbine blade root insert which may be formed from a blank.

An article-forming tool comprises an elongate jig having a predefined shape, an elongate flexible vise configured to hold a fiber-composite article of a predefined cross section, and a spacer system. The vise opposes the jig; it includes a series of clamp segments and a flexible spline sheet configured to conform controllably to the shape of the jig. The clamp segments are arranged side-by-side along a length of the vise, each clamp segment comprising a set of platens configured to hold a corresponding longitudinal segment of the article. The flexible spline sheet extends through the series of clamp segments, between opposing platens. The spacer system is configured to control the conformation of the spline to the shape of the jig.

A wind turbine blade mold system having built in precision pins to locate structural components (e.g. spar caps) during layup of composite segments. A plurality of pins can be inserted through the layers of composite layups and into apertures within the mold, with spar caps positioned against the pins to ensure precise positioning, thereby preventing/inhibiting movement of the spar cap relative to the mold. A plurality of pins can be inserted through the layers of composite layups and into apertures within the mold, with cams attached to the pins and moveable to engage spar caps to ensure precise positioning of the spar cap, as well as preventing any drift during subsequent operations. The pins can remain embedded within the final molded part.

According to one implementation, a composite material structure includes a corrugated stringer and a panel. The corrugated stringer has a corrugated structure including portions each having hat-shaped cross section. The corrugated stringer is made of a composite material. The panel is integrated with the corrugated stringer. The panel is made of a composite material. Further, according to one implementation, a manufacturing method of a composite material structure includes: setting a textile on a laminated body of prepregs; and producing the composite material structure by covering the laminated body with a bagging film, forming a vacuum state in a space covered with the bagging film, impregnating the textile with the resin, and thermal curing of the laminated body of the prepregs. The laminated body is a panel before curing. The textile has a structure corresponding to a corrugated stringer.

A method produces a fiber composite component for a motor vehicle. The method provides a semifinished fiber composite blank, wherein the semifinished fiber composite blank includes reinforcing fibers and a matrix material. The semifinished fiber composite blank is arranged between a first membrane and a second membrane. The semifinished fiber composite blank is shaped into a fiber composite molding by pressing the semifinished fiber composite blank together with the first membrane and the second membrane via a pressing device, and the fiber composite molding is consolidated.

A curing mold for manufacturing a turbomachine part made of composite material from a preform produced by draping pre-impregnated materials includes: a first body and a second body designed to be attached to each other and jointly defining a fixed air gap for receiving the preform and itself including a molding part of complementary shape with the part to be manufactured and intended to receive a portion to be molded of the preform, and at least one additional part located in a peripheral space of the air gap and intended to receive an additional portion forming an edge of the preform; a heating member designed to heat the preform in the air gap to a first temperature; at least one inflatable bladder housed in the first or second body, facing an additional part of the air gap; a member for injecting a pressurized fluid inside the bladder(s).

A method and system for managing tow end placement. A tow is laid up over a tuning surface. A first position of a first tow end of the tow and a second position of a second tow end of the tow are measured. A first error between the first position of the first tow end and an expected position for the first tow end, and a second error between the second position of the second tow end and an expected position for the second tow end, are computed. A determination is made as to whether at least one of the first error or the second error is outside of selected tolerances. A start timing offset of a tow placement system is adjusted if the first error is outside of selected tolerances and a stop timing offset of the tow placement system is adjusted if the second error is outside of selected tolerances.
