The present disclosure relates to a prepreg, a preparation method thereof and a fiber-reinforced composite material prepared therefrom. The preparation method of a prepreg may include an aramid fiber base material with improved wettability to resin, can increase a thickness reduction rate during molding of the prepreg, has an appropriate resin content, and can provide a prepreg suitable for molding by an out-of-autoclave process. In addition, the prepreg may provide a fiber-reinforced composite material that exhibits a thin thickness and a high resin content even by an out-of-autoclave process, and shows high strength and low moisture absorption

Methods and manufactures disclosed herein generally relate to a cannular composite (ITC) structure composed of multiple layers of sealing, reinforcement, sensing, protection, and interspatial injected materials.

The present invention provides an anti-slip apparatus. The apparatus forms a planar, layered member and includes a glass-reinforced plastic (GRP) layer, a first resin layer, an abrasive or anti-slip material layer, and a second, top resin layer. Also provided is a template apparatus arranged to enable the installation/application to a floor or surface of an anti-slip apparatus as herein described.

The present disclosure relates to a shaft for athletic activities comprising, along at least a part of the length of the shaft: an internal wall (31) made of a first fiber-reinforced composite; and an external wall (30), fixed to the internal wall, and made of a second fiber-reinforced composite, wherein one or more cavities (32A, 32B, 32C) are present between the internal wall and the external wall.

During a manufacturing method, a preform is arranged with a plurality of grips. The preform includes a stack of a plurality of layers of material. The grips are disposed along a periphery of the stack. The preform is formed into a shaped body. The forming includes pressing a die against the stack and gripping the stack with the grips during the pressing of the die. The gripping includes asynchronously gripping the stack with at least some of the grips.

Methods, apparatus, and systems for cutting material used in fused deposition modeling systems are provided, which comprise a ribbon including one or more perforations. Material is passed through at least one perforation and movement of the ribbon cuts the material. A further embodiment comprises a disk including one or more blade structures, each forming at least one cavity. Material is passed through at least one cavity and a rotational movement of the disk cuts the material. A further embodiment comprises a slider-crank mechanism including a slider coupled to a set of parallel rails of a guide shaft. The slider moves along a length of the rails to cut the material. Yet another embodiment comprises one or more rotatable blade structures coupled to at least one rod. The rotation of the blade structures causes the blade structures to intersect and cut extruded material during each rotation.
