CompositesWorld.com 11 AFRW building Perhaps the most impactful seminar for composites was "Developing Sustainable Solutions for End-of-life Fiberglass Boats," presented by Evan Ridley and Wendy Mackie of the Rhode Island Marine Trades Association (RIMTA, Bristol, RI, US). A pilot recycling network has been established by RIMTA in collaboration with other state organizations and government agencies. Modeled after a successful German system, the 2018 Rhode Island Fiberglass Vessel Recycling (RIFVR) project will collect end-of-life boats, drain their fluids, remove engines, metals and electronics, and then work with industry partners to shred fiberglass composite structures. This recyclate will then be trucked to a cement kiln where it will be used as fuel. It also may be combined with composite production waste — e.g., resin-filled vacuum bags, scrap laminate and resin — which increases the BTU content for the energy-inten- sive cement kilns. The potential impact of this project is significant, enabling a technological leap for the composites industry in closing the loop and achieving zero-landfill manufacturing. RIMTA is seeking financial backing, but also partners to help with logistics, R&D and expan- sion to other durable waste streams (e.g., composite production waste), as well as further collaboration with cement industry partners. With this project's success, the composites industry should continue forward, refin- ing and expanding across the country and into other markets, such as wind power, where first-generation composite turbine blades are beginning to be replaced. Another highlight at the show was recognition of Structural Composites Inc.'s (West Melbourne, FL, US) development work that won it the IBEX 2018 Innovation Award in the Boatbuilding Methods & Materials category — Structural Composites' CoCure Technology used in Interplastic Corp.'s (St. Paul, MN, US) new Advanced Marine Coatings. Comprising a polyester/polyure- thane hybrid, these coatings offer a 200% increase in impact resistance, with a 70% increase in elongation, offering boatbuilders a tougher, more flexible exterior surface and increased design freedom in the underlying composite structure. In addition, Advanced Marine Coatings can be "tuned" for different strain requirements, with tough- ness tailored from rigid to elastomeric. This prod- uct line also reportedly provides a 20% decrease in hazardous air pollutant (HAP) content vs. conven- tional gelcoats. Structural Composites president Scott Lewit reviewed the technology development work in an IBEX technical seminar, noting that new formula- tions are in testing for the RV market, offering up to three times the weathering performance of current polyester gelcoats. IBEX 2019 is scheduled for Oct. 1-3, 2019, at the Tampa Convention Center, where the show will remain for the next three years. For more information, visit ibexshow.com. CONSTRUCTION Teijin Ltd. (Tokyo, Japan) announced that it will construct the world's first building made of advanced fiber-reinforced wood (AFRW), a structural timber product comprising a number of layers of dimensioned timber and high-performance fibers bonded together with structural adhesives. Teijin first devel- oped the materials in 2015, which involved incorporating high-toughness aramid fibers and highly stiff carbon fiber, and hybrid materials incorporating these fibers. The new building, which will be constructed in Teijin's Tokyo Research Center in Hino City, Japan, exploits the warm texture and unique timber composition of AFRW to help create a stress-free environment. It also aims to realize open and comfortable space by avoiding the use of columns, thus maximizing the inflow of natural light. The project was approved by Japan's Ministry of Land, Infrastructure, Transport and Tourism (MLIT, Tokyo) in May and construction was set to begin in October, with technical support provided by the professional construction firm Maeda Corp. (Tokyo) and the Structural Engineering Laboratory of Kochi University (Kochi, Japan). Upon completion, Teijin and Maeda will monitor adhesive stability and the vibration dura- bility of AFRW for a period of seven years. Teijin will continue to develop AFRW technology follow- ing construction of this first building and the initial moni- toring phase. The aim is to realize safe, comfortable, earthquake-proof wooden buildings as well as the develop- ment of sustainable architecture using timber as sustainable resources that absorb CO 2 . The company expects the new technology and materials to be deployed in general construc- tion by around 2020. Teijin to build advanced fiber- reinforced wood building Source | Teijin Ltd.
