The Boeing Dreamliner has been a great test bed for new materials technologies. To date, though, molding technologies have taken a backseat to more traditional composite forming processes, such as those used to form large boat hulls. That may be changing, though, as Boeing engineers look for ways to squeeze weight from the aircraft. A Pennsylvania company is now making net shape assembly brackets from compression molded carbon composites made with engineering thermoplastics, such as PEKK. Greene, Tweed uses a proprietary process called ProFusion that uses highly controlled temperature cycles to boost the flow properties of the material. It’s not known if these parts are used on Boeing aircraft.
