NEWS 27 SAMPE Keynote Russia-based Irkut's MS-21 wing, made via automated fiber placed dry tape infused with toughened resin. "I don't believe aluminum and titanium accomplished as much in their first 30 years as composites have in their first 30 years," he argued. Can we claim victory? Lo Faro asked. In short, he answered, no — a lot more can be done. To grow further, composites must deliver more value, he said. Future chal- lenges and opportunities might include press forming, thermoplastic composites for large structures, additive manufacturing, joining, simulation, managing complexities, and, of course, cost. LoFaro did inject "a little caveat — the hype cycle," where interest becomes exaggerated enthusiasm (hype), and then, "after a time of disillusionment," finds its place in reality. The future, he said, will be driven by industrial scale and econo- mies; convergence of aerospace and automotive practices; and the increased importance of production systems vs. end-products. Moving on to thermoplastic composites, Lo Faro discussed PEEK, PEKK, PAEK and continuous compres- sion molding. Thermoplastic composites are not new, he reminded his listeners. Further, he expects growth in the 21st Century to be enabled by maturation of cost-effective, automotive-like manufacturing processes developed in the past 15 years: notably compression molding, continuous compression molding and stamp forming. If the aerospace supply chain is to develop and build large thermoplastic composite structures then it must mature out-of-autoclave molding/forming systems capable of rapid heating/cooling. Lo Faro also touched on additive manufacturing (AM). Initially, he said, AM can support manufacture of tooling and fixtures. In the future, AM can provide on-demand tool manufacturing, and can improve composites maintenance and repair operations (MRO). Here too, he said, are oppor- tunities to couple AM with machine learning. However, he said, more collaboration is needed between machine and material suppliers. Lo Faro went on to name three important simulation and modeling needs for the composites industry: • Molecular modeling — informing experimentation and increasing speed to market • Artificial intelligence — applied to materials design and discovery • Certification by analysis — which he called the Holy Grail These technologies have the potential to shorten development time through optimized molecular design for improved properties, changing the way the materials themselves are developed. The future is now, he said, for multi-scale modeling to accelerate composites innovations and adoption and failure prediction. Lo Faro finished optimistically: "When we look at the next 40 years, I believe composites are a material that will exceed the capabilities of metals." High Performance Tooling for the Composites Industry • Steel • Invar • NVD Nickel • Aluminum • Precision Machining Nickel Vapor Deposition capability has led us to be the leading supplier for shell tooling with integrated heating.
