Provided is a method of manufacturing an adaptable pre-cast resin-infused carbon-fiber beam, which method includes the steps of arranging a plurality of elongate carbon-fiber blocks side by side; arranging sheets to enclose the blocks and to extend over opposing faces of adjacent blocks; arranging the sheets to converge as an outwardly projecting elongate bead at a junction between adjacent blocks; and pulling on the elongate bead to inhibit resin flow between blocks during a resin infusion step. Also provided is a pre-cast adaptable carbon-fiber beam manufactured using that method; a method of manufacturing a wind turbine rotor blade; and a wind turbine rotor blade.

The present disclosure provides a lightweight spar cap with a concave structure for a wind turbine blade and a manufacturing method thereof, a wind turbine blade and a manufacturing method thereof. The lightweight spar cap is groove-shaped as a whole, and includes supporting portions located on two wings of the lightweight spar cap and an intermediate connecting portion connecting the two supporting portions. The manufacturing method of the lightweight spar cap includes laying a reinforcing body of the intermediate connecting portion and a supporting material of the supporting portion, and performing resin infusion. By comprehensively considering multiple factors, the present disclosure reduces the weight of the wind turbine blade, improves the material utilization of the wind turbine blade, and realizes a lightweight wind turbine blade.

Liquid shim injection devices and methods for injecting liquid shim material into a gap between adjacent components of an assembly. The liquid shim injection devices comprise a body, which comprises an injection shaft, a liquid shim conduit defined within the body and configured to channel liquid shim material within the injection shaft, and a fluid-permeable region formed along the injection shaft, an actuated fluid seal operably coupled to the injection shaft and configured to be selectively conformed among a plurality of conformations, and a fluid seal actuator assembly configured to transition the actuated fluid seal among the plurality of conformations. Methods comprise inserting the injection shaft into a bore that extends through the adjacent components of the assembly, forming a fluid seal between the liquid shim injection device and an interior component of the assembly, and flowing the liquid shim material from the liquid shim injection device into the gap.

Structure intended to stiffen a component made of thermosetting composite material by being fitted to at least one of its surfaces, including: at least one longitudinal body, with first and second longitudinal edge faces on opposite sides, and first and second lateral faces on opposite sides; at least one base including at least one mounting base, each base having a plate and first and second tongues which delimit, with the plate, a housing for at least one body, the first and second tongues extending from a main face of the plate and being pressed respectively against the first and second lateral faces of the body. Each mounting base has a plate which is secured to the first longitudinal edge face of a body and which is intended to be pressed against the surface of the component to be stiffened. Each body and each base are made of thermosetting composite material.
