摘要： A single-leaf spring comprising a body and two eyes located at the ends of the body, with the body having an upper side and a lower side, that comprises at least one composite material sheet comprising a series of fiber sheets embedded in a polymer matrix to form a single-leaf spring, where the sheet is a single sheet that runs longitudinally along both sides of the body and the eyes of the leaf spring and that by having both sides folded creates the eyes of the leaf spring.

摘要： Non-standard, resin-infused fiber bundle includes localized regions of fibers having a sub-nominal amount of polymer resin positioned along its length. These regions function as “bending regions,” where the non-standard resin-infused fiber bundle can be readily deformed by virtue of the reduced amount of resin. The bending regions segregate the non-standard resin-infused fiber bundle into what is, effectively, discrete (smaller) segments of (standard) resin-infused fiber bundle. The ability to easily manipulate the non-standard, resin-infused fiber bundle via the bending regions is useful for creating fiber-bundle-based preforms, and preform charges (assemblages of fiber-bundle-based preforms).

摘要： A pultruded strip (50) of reinforcing material for stacking with one or more similar strips (50) to form a spar cap for a wind turbine blade is disclosed. The pultruded strip comprises a core (56) comprising fibres (58) disposed in a resin matrix (60) and a sacrificial layer (52) at least partially covering one or more surfaces of the core (56). The sacrificial layer (52) is a resin layer defining an adherend surface (62A) of the strip. A pultrusion process for making such a strip (50) comprises drawing resin-coated reinforcing fibres (58) through a pultrusion die (80) in a process direction to form a core (56) of the strip (50) and applying further resin (53) to one or more surfaces of the core (56) to form a sacrificial resin layer (52) defining an adherend surface (62A) of the strip (50).

摘要： An additively manufactured structure and methods for making and using same. An object can be printed at least partially on an attachment portion. The attachment portion can be bonded to the object upon the printing. The object does not need to be removed from the attachment portion. The need of providing a print surface to allow easy removal of the object is eliminated. The object can be a flat panel and can eliminate the need of printing a large flat layer using additive manufacturing. The attachment portion can be cut prior to the printing, so no trimming needs to be performed after the printing. The attachment portion can be made of a material that has one or more selected properties to expand functionalities of the object. A secondary operation for attaching the attachment portion to the object after the printing can be eliminated.

摘要： Embodiments are directed toward compression molding a polymeric product. The method preferably includes creating a casting mold. Elastomeric material is preferably placed in the casting mold. The elastomeric material is preferably allowed to at least partially cure in the casting mold to define a plug body. The plug body is preferably removed from the casting mold. A female compression mold is preferably provided. Polymeric material is preferably placed in the female compression mold. The polymeric material is preferably compressed in the female compression mold with the plug body to compression mold a polymeric product.

摘要： A stiffening element comprises a tension and compression member, a shear member, an attachment member, and a plurality of beads. The tension and compression member is positioned spaced apart from the skin and configured to bear tension or compression forces that stiffen the skin and prevent the skin from buckling or bending. The shear member is connected to the tension and compression member and configured to bear shear forces between the skin and the tension and compression member. The attachment member is connected to the shear member and is configured to connect to the skin. The beads each create out-of-plane feature that is positioned in at least one of the shear member and the attachment member. The beads permit the stiffening element be reshaped to adjust a longitudinal curvature of the stiffening element.

摘要： Thermoplastic elastomer compounds include (a) at least about 40 weight percent of thermoplastic polyurethane selected from polycaprolactone-type thermoplastic polyurethane, polyether-type thermoplastic polyurethane, and combinations thereof, and (b) at most about 5 weight percent of polysiloxane. The thermoplastic elastomer compounds can be molded into thermoplastic articles which exhibit substantially no blooming after weathering, while also exhibiting good processability, useful functionality, and desirable aesthetics. The thermoplastic compounds can be especially useful for making overmolded thermoplastic articles.
