Market outlook Jacobson and Champion say the machine can process autoclave or out-ofautoclave thermosets, has applicability to aerospace manufacturing and could be used to process thermoplastics as well. Globe is testing aerospace parts in 2013 and hopes to receive an OEM process procedure approval for aerospace use sometime in early 2014. Tapping a similar vein was Dale Brosius, president, Quickstep Composites LLC (Dayton, Ohio), who reviewed his company's automated through-thickness infusion and rapid-cure process. It uses resin spray transmission (RST) in a process that, Brosius says, approximates semipreg. In RST, the user starts with an open, empty mold. The mold is sprayed with a thermoset resin. A carbon fiber fabric preform is placed over the sprayed mold surface. The mold is then closed and the part is cured. The system, says Brosius, offers rapid heating and cooling (30°C to 40°C/min), 10-minute part-to- W yoming T est F ixtures INC.

The material costs are said to be 20 to 40 percent less than prepreg, and parts can be either painted or clearcoated. Quickstep is selling and licensing the technology globally and, Brosius added, has placed a machine that, at HPC press time, is set to begin operation in the first quarter of this year. Exhibitor Dieffenbacher North America (Windsor, Ontario, Canada) introduced its high-pressure resin transfer molding (HP-RTM) process, aimed at manufacturing automotive carbon fiber composites. Dieffenbacher officials at the conference said the company has developed machinery to automate fabric preforming, molding and finishing. Molding is performed at pressures of 80 to 100 bar (1,160 to 1,450 psi) and offers part-to-part cycle times of about three minutes. The process, said Dieffenbacher, is being used by a European automotive OEM to manufacture B-pillar structures for a production vehicle. Next year, Tennessee Other presentations at the conference covered a comparison of metallic and composite wings, design and engineering of large antenna structures, carbon fiber use in electricity transmission lines, automated dry fiber placement and design of reinforcements for damage tolerance.
