20230002591 · 2023-01-05 · ·

The present disclosure generally relates to systems and methods for composites, including short-fiber films and other composites. In certain aspects, composites comprising a plurality of aligned fibers are provided. The fibers may be substantially aligned, and may be present at relatively high densities within the composite. For example, the composite may include substantially aligned carbon fibers embedded within a thermoplastic substrate. The composites may be prepared, in some aspects, by dispersing fibers by neutralizing the electrostatic interactions between the fibers, for example using aqueous liquids containing the fibers that are able to neutralize the electrostatic interactions that typically occur between the fibers. The liquids may be applied to a substrate, and the fibers may be aligned using techniques such as shear flow and/or magnetism. Other aspects are generally directed to methods of using such composites, kits including such composites, or the like.

METHOD FOR MANUFACTURING A WIND TURBINE BLADE

A method for manufacturing a wind turbine blade, includes the steps of: arranging an upper mould including a pre-casted fibre lay-up on a lower mould comprising a dry fibre lay-up and a mould core, applying vacuum to a space between the upper and lower moulds and the mould core, infusing at least the dry fibre lay-up and a connection region between the dry fibre lay-up and the pre-casted fibre lay-up with a resin, and curing the resin.
