Hexcel (Stamford, Conn., USA) celebrates its 65th anniversary this year, and is promoting several new developments. HiTape Advanced Reinforcements for out-of-autoclave processing of primary aircraft structure are unidirectional tapes made with HexTow carbon fiber aimed at automated layup processing, and reportedly allow deposition rates as high as 50 kg per hour. The company’s new HexPly M91, a new epoxy prepreg for airframe structures and engine parts, has high toughness and high residual compression after impact (CAI) strength. HexTOOL machinable composite tooling material was recently selected by manufacturer CFAN (San Marcos, Texas) for tools to support its jet engine fan blade program. And also featured will be a new very lightweight reinforcement: PrimeTex spread-tow 3K carbon fabric, which is reportedly 12 percent thinner than conventional 1K carbon fabrics, for very light components.
