NOVEMBER 2018 4 CompositesWorld FROM THE EDITOR » Many years ago, when I was in college and studying jour- nalism, one of the first classes I took was on basic journalistic reporting. is is the task of collecting information about an event, person or place and then presenting that information in a clear, succinct, easy-to-read format for the audience. In 1987, when I took this class, the format was primarily print media, either newspaper or magazine — the concepts of digital media, social media and the Internet did not yet exist. Our reporting class focused on telling stories about the types of events we were likely to encounter as journalists: Public meetings, political speeches, crime scenes, etc. One of my professors, eager to demonstrate the difficulty of using written language to clearly convey information, had us perform a simple exercise. We were given 10 minutes to write step-by-step instructions on how to tie a lace on a shoe. We were then instructed to trade our instruc- tions with another student in the class, untie our own shoes and then follow the instructions we were given — to the letter — to re-tie our shoes. e question was simple: Could we write instruc- tions well enough that a person could use them to tie shoe laces. e short answer is "no," although some of us came pretty close. (If you doubt the difficulty of this assignment, I suggest you try it with your own friends and family, but don't blame me for whatever arguments ensue). is shoe lace-tying exercise has been brought to my mind often over the last several years as I edit the stories we publish in CompositesWorld. I say this not to cast aspersions on CW's writers and contributors — they are as well-versed in shoe-tying as they are in composites design, engineering and fabrication. I say this because CW operates in a composites industry that has proven admirably adept at generating complex, fast-evolving materials and processes that often are difficult to explain with the written word. Take, for example, senior editor Ginger Gardiner's story this month on filament winding (p. 24). As she was doing research for this story, Ginger called me one morning about a new technology she'd just unearthed. It was, she said, developed by Daimler and dubbed FibreTEC3D. Here's what Ginger said, as I remember it: "It's not really filament winding, but it uses filament winding concepts. ere's no mandrel and no core, but it does use a towpreg-like material, which is wound around a series of vertical aluminum or steel pins by a multi-axis robot. It's room-tempera- ture cured, so no autoclave or oven." Got that? Neither did I, until I backed Ginger up several sentences and sorted out what she was telling me. Fortunately, you can see, and read about, this system for yourself on p. 24, and you can under- stand immediately how inspired and creative it is. Technology like what Ginger found is par for the course, and finding the words to explain it is a big part of what we do. For almost every story we publish, we look for some basic raw data covering a range of topics: Application requirements, design chal- lenges, resin type, fiber type, fiber format, tooling type, manu- facturing process, manufacturing parameters, finishing process, inspection protocol and assembly requirements. en, we take what we get and put it all together to tell a story. It's during the editing process that we work hardest to verify we are telling a story that makes sense and has value and utility for you — that we are, to complete the metaphor, helping you understand how that shoe is tied. Rare, of course, is the story that sheds full, unbridled light on an application or process, but we like to think that we come close more often than not. Fortunately, we get a lot of practice, for there is no shortage of innovation and change in composites manu- facturing for us to document and chronicle. And such a dynamic environment is not only great fun to be a part of, but it also drives the evolution of composites. There is no shortage of innovation for us to document.
