Novel ultra-thin unidirectional pre-preg tapes are disclosed. They can be used to produce ultra-thin woven, bias, multiaxial, chopped-oriented etc. types of pre-pregs. These ultra-thin pre-pregs enable production of composite material products with well-controlled dimensional tolerances and smooth/even surfaces. Further, they render the production of composite material products relatively simpler, tidier, quicker, and economical. The obtained composite material products are relatively thinner, lighter, and mechanically higher-performing.

Ultra-thin pre-preg sheets and composite materials thereof

A tape-like dry fibrous reinforcement, the 'Gapped UD reinforcement tape', providing channels or flow-paths created by inclusion of a layer of separated fiber tows held by at least one adhesive layer. Hereby, quicker wetting of fibers with matrix is obtained, whereby improved composite materials can be economically produced. A method and apparatus for producing the Gapped UD tapes are also disclosed.

A battery cell includes an anode, a cathode, and a separator between the anode and the cathode, wherein at least one of the anode or the cathode includes at least a carbon fiber ply comprising carbon fibers, the carbon fiber ply having a thickness of less than 90 micrometers. Also disclosed are a battery and an aircraft including such battery cell, and a method for manufacturing such battery cell.
