摘要： The present disclosure provides an apparatus that includes a fiber gun. In an embodiment, the apparatus may controllably cut one or more fibers into one or more fiber segments. In an embodiment, the apparatus may controllably shape one or more fibers into different shapes (e.g., from loops into substantially straight fibers). In an embodiment, the apparatus may controllably position the one or more fiber segments onto a supporting member (e.g., a composite component). For example, the apparatus may include a robot that may controllably move the fiber gun relative to a supporting member and align the fiber gun such that the one or more fiber segments are controllably positioned on the supporting member. The apparatus may further include a controller that at least partially controls operation of the apparatus.

摘要： In order to recycle glass fiber/fiber fabric production waste material, such as a material used in the manufacturing of rotor blades for wind turbines, and preferably where the material is bendable or flexible and reinforced in a plurality of layers in one or more directions in planes that are parallel with the surface of the material and stitch bonded together, the material is mechanically processed involving a size reduction of the material into shorter fiber length, in order to convert the material into one or more substantial pure glass fiber products. In this way it is possible inter alia to further process the material and create materials such as acoustic insulation wool, and chopped glass fiber strands.

摘要： The present invention is intended to provide an organic resin non-crimped staple fiber that has notably few defects and that uniformly disperses in a dispersion medium, and that is preferred for use in wet-laid nonwoven fabrics or resin reinforcement in applications such as in industrial materials and daily commodities. The organic resin non-crimped staple fiber of the present invention has a fineness of 0.0001 to 0.6 decitex, a fiber length of 0.01 to 5.0 millimeters, a moisture content of 10 to 200 weight %, a cut-end coefficient of 1.00 to 1.40, and a coefficient of variation relative to fiber length (CV %) of 0.0 to 15.0%, the cut-end coefficient and the coefficient of variation relative to fiber length being defined as follows: (1) Cut-End Coefficient=b/a, wherein a is the fiber diameter of a single yarn of the non-crimped staple fiber, and b is the maximum diameter at the cut end; (2) Coefficient of Variation Relative to Fiber Length (CV %)=(standard deviation of fiber length)/(mean value of fiber length)×100(%), wherein the number of measured single yarns is 50 in (1) and (2). The foregoing object can be achieved with this configuration.
