A method or process for making one or more components of a head fixation device includes preforming, molding, and finishing subprocesses. The preforming subprocess includes placing fibers onto a substrate to orient the fibers parallel to a flux of force that the component is expected to experience in use. The fiber layers are combined and can be draped over an optional core before being molded to combine the assembly with a molding material. The resultant molded preform undergoes a finishing subprocess that can include smoothing the component to remove any burrs or sharp edges from the molding subprocess.

The method further includes reshaping the fibre core composite and impregnating and consolidating the hybrid fibre braid on the core element.

A non-metallic rim for a wheel which may be used for motorised vehicles. The rim has a barrel, a first flange, a second flange, a first bead seat, a second beat seat and a primary structural component. The primary structural component extends into at least the first flange and the barrel, and the primary structural component is capable of bearing the majority of the radial and/or lateral load that is borne by the rim during usage. Additionally, the rim has at least a portion of the first bead seat spaced apart from the primary structural component and/or has a protective insert in between the outer face of the first flange and the primary structural component.

A tank including a liner; a reinforcing layer formed of fiber reinforced resin that is arranged on the liner; a label arranged on the reinforcing layer; and a surface layer formed of glass fiber reinforced resin that is arranged to cover the label. The reinforcing layer includes an inner layer, and an outer layer having a cover rate smaller than the inner layer and smaller than 100%, the cover rate being a percentage of a volume occupied by the fiber reinforced resin in space of the reinforcing layer, and the outer layer being arranged on the inner layer, and at least a part of the label is embedded in the reinforcing layer.

The invention relates to a reinforcement, containing fibers and resin, for an element made of a composite material, particularly a wind turbine blade, characterized in that the reinforcement is produced by stacking at least two parts produced by pultrusion. A reinforcement, containing fibers and resin, for an element made of a composite material, particularly a wind turbine blade, is characterized in that the reinforcement is produced by stacking at least two parts produced by pultrusion.

A pultrusion method, equipment for preparing a fiber-reinforced composite, and a fiber-reinforcement composite are provided. The pultrusion method comprises the following steps: i) preforming inner layer fibers; ii) impregnating the preformed inner layer fibers with a first resin to obtain a first preform; iii) heating and curing the first preform to obtain an inner layer profile; iv) preforming outer layer fibers together with the inner layer profile; v) impregnating the outer layer fibers with a second resin to obtain a second preform; and vi) heating and curing the second preform to obtain the fiber-reinforced composite.

A manufacturing method contemplates performing vacuum-assisted resin infusion to enclose an elongated core within a cured composite laminate without employing a mold. Not relying upon an external mold enables the process to be efficiently performed for core shapes that are manufactured in low volumes. Typical resin infusion processes utilize flow media that induces bag bridging during vacuum draw in order to provide gaps facilitating resin flow. However, popular flow media also tends to impart directional aggregate forces during vacuum draw, which forces can deform the core since no mold is being used. To avoid unequal and non-dispersed directional forces from deforming the elongated core, a flow media is employed that is configured to disperse and/or reduce such forces. Some such flow media may be knitted so as to allow overlapping strands to slide over one another. Other flow media may ensure that strands are interleaved so that no one strand or group of strands is disposed outwardly of other strands along a substantial length of the strands, thus dispersing bag bridging forces in several directions and avoiding directional aggregate forces. However, such flow media may have inhibited resin flow relative to popular high-flow flow media, and thus new strategies have been developed to ensure appropriate wetting of fibrous reinforcement. An adjustable brace can also be employed to restrain the elongated core from deflecting during application of vacuum and/or resin infusion.
