TRENDS INDUSTRIAL JULY 2017 14 CompositesWorld The payload capacity of a crane depends on the strength and stiffness of the materials used to make the arm. It also depends, ironically, on the arm's weight. That is, the greater the arm's weight, the less payload it can bear. Conversely, you can increase the payload capacity of the crane by reducing the mass of its arm. In other words, the crane arm is an ideal application for composites. The Manitowoc Co., a crane manufacturer located in Shady Grove, PA, US, recognized this advantage and decided to target the stinger or fly jib — the final segment of a articulating crane arm — on one of its truck-mounted cranes, replacing the traditional 24-ft (7.3m) steel struc- ture with one of carbon fiber composite. Sammy Munuswamy, senior principal engineer, global engineering and innovation at Manitowoc, says the company is "in the business of building lifting experiences for our customers around the world." And a quality "lifting experience," in Manitowoc's view, should be one where the tool (crane) facilitates the jobs to be done at a variety of jobsite environments, including buildings, roadsides, heavy construction sites and more. "Cranes are getting lighter," Munuswamy says, "and we need materials to meet that expectation.

Composites preforms can now be manufactured by automated processes, such as automated fiber placement (AFP) and automated tape laying (ATL), to achieve the expected production volumes. is presentation will illustrate how Coriolis Software and Siemens PLM Software products can help composite designers, stress engineers, and NC programmers to collaborate together to optimize the design and manufacturing of complex CFRP laminates made by automated layup machines. PARTICIPANTS WILL LEARN: • how to predict manufacturing issues early in the design stage • how to improve the collaboration between composite design, stress analysis, and NC programming • the key factors for design for manufacturing with automated layup robots • how to optimize part design - doing trade-off studies with machine limitations and for various material types Lightweight Composite Design with Automated Layup Manufacturing July 19, 2017 • 11:00 AM EST REGISTER TODAY FOR WEBINAR AT: short.compositesworld.com/Siemens719 LEIGH HUDSON Business Development, Siemens PLM Software
