FEBRUARY 2018 12 CompositesWorld PERSPECTIVES & PROVOCATIONS » Perusing my bookshelves recently, I came upon a book I'd read more than 20 years ago, titled And Suddenly the Inventor Appeared, by Genrich Altschuller, a Russian inventor. It's a treatise on TRIZ, the theory of inventive problem solving. Its premise is that any invention is ultimately the result of the application of physics, although the path to the solution is not always the obvious one. e world is full of famous inventors (and inventions), going back, at least, to Archimedes, with his conveying screw, and his use of buoyancy to derive material densities (per legend, an idea he conjured while bathing). Inventions change things. Some inven- tions change everything. Johannes Gutenberg, who introduced moveable type for printing presses, and Leonardo da Vinci's numerous inventions ushered in the modern period of human history. e creation of the patent system provided legal protection to inventors that afforded them the time and opportunity to monetize their ideas. e industrial revolution gave us Watt, Whitney, Deere, Benz, Daimler, Ford, Tesla, Bell, Firestone and perhaps the world's most famous inventor, omas Edison. Referring to his deliberate method of discovery, Edison famously claimed, "Genius is 1% inspiration and 99% perspiration," to dispel the notion that inven- tions are mainly the result of accidents or are stumbled upon by those pursing other goals. In 1947, William Shockley's invention of the transistor and the commercialization effort that followed in California is believed to be the genesis of today's Silicon Valley. e composites world is not short of well-known inventors, starting with Leo Baekeland, the creator of the first synthetic resin, phenolic. Trademarked as Bakelite, thermosetting phenolics quickly found numerous uses in neat form, but also as a binder for mineral and fibrous fillers, both discontinuous and continuous. Phenolic composites are used extensively today, in aircraft inte- riors, oil and gas applications, fire-resistant building and train panels, and high-voltage electrical components. e first patent for resin transfer molding (RTM), issued in 1950, is often referred to as the Marco Process, assigned to Marco Chemi- cals in New Jersey by the lesser known inventor Irving Muscat. e process and patent are often cited in later patents for all sorts of resin infusion techniques, including variations of vacuum-assisted RTM (VARTM), such as the Seeman Composite Resin Infusion Process (SCRIMP), patented by Bill Seeman. Robert Morrison, founder of Morrison Molded Fiber Glass, has been involved in many innovations, none more famous than the press-molded composite body panels for the pioneering 1953 Chevrolet Corvette. e most lauded inventor in the composites industry is probably the late Brandt Goldsworthy, who was granted well over 50 patents for composites processes, including straight and curved pultrusions, CNC filament winding and tape placement, among others. From his inventions, and the companies he founded or helped found, has sprung a robust composites industry built on lower cost, automated manufacturing. I've been fortunate during my career in composites to come across numerous inventors. Some are itinerant tinkerers, working out of a garage or shed — like the founders of Hewlett Packard and Apple. Others have the advantage of tinkering inside corporate laboratories. Some employ deliberate methodologies that would make Edison proud. Others simply reach out experimentally, relying on the random epiphany for that "Eureka!" moment. For example, the inventor of the Quickstep curing process, a floating, balanced pressure, liquid heating and cooling process, claims to have come up with the idea while sitting in his bathtub — his own Archimedes moment! My favorites have been the serial inventors, those with multiple ideas that have reached various states of commercialization. One friend of mine in the US has come up with novel ways to recycle thermosets, developed metals that heat and cool molds rapidly, resins for infusing (and improving the strength of ) 3D printed powder structures, and very high-temperature and fire-resistant thermoset resins, among other creations. A friend in the UK, whom I consider one of the best I've met at thinking outside the box, has developed a number of lightweight vehicle platforms, a patented method of metalizing carbon composites, and low-cost methods for fabricating large, structural sandwich panels, using a mix of virgin and recycled carbon fibers. Not only are both serial inventors, they are also serial entrepreneurs. I know many others just like them, who open my eyes to what is possible. What they, and others like them are doing, is essential to keeping the composites industry vibrant and ever improving. Not every invention or innovation is a commercial smash, but that should not limit us from encouraging novel ideas, no matter how they are conceived or how improbable they might seem. And suddenly the inventor appeared Dale Brosius is the chief commercialization officer for the Institute for Advanced Composites Manufacturing Innovation (IACMI, Knoxville, TN, US), a US Department of Energy (DoE)- sponsored public/private partnership targeting high-volume applications of composites in energy-related industries. He also is the head of his own consulting company, and his career has included positions at US-based firms Dow Chemical Co. (Midland, MI), Fiberite (Tempe, AZ) and successor Cytec Industries Inc. (Woodland Park, NJ), and Bankstown Airport, NSW, Australia-based Quickstep Holdings. He has served as chair of the Society of Plastics Engineers' Composites and Thermoset Divisions. Brosius has a BS in chemical engineering from Texas A&M; University and an MBA. Inventors and their inventions are essential to keeping the composites industry vibrant and ever improving.
