What opportunities for training and professional development has the project provided?We offered two courses in close collaboration with UO Architecture & Allied Arts. Mariapaola Riggio teamed with UO's Nancy Cheng to offer Timber Tectonics in the Digital Age where students designed and produced three-dimensional concepts. Ruth Fore joined her UO course with Wood Machining III. Students collaborated to design, develop, manufacture and sell products made from bamboo (donated by Smith and Fong in San Francisco http://www.plyboo.com/). We developed a totally new approach to professional mentorship for Renewable Materials undergrads. Chris Knowles and Michelle Maller lead this initiative that includes ongoing advising during a student's time with RM, providing numerous opportunities for students to network with industry, and assisting with internships and permanent employment. Six RM students attended the North American Wholesale Lumber Association Trader's Market in fall 2016 where they were speakers in a panel session and networked with 1,500+ industry professionals. We completed a major overhaul of the RM curriculum including the addition of a new option, Advanced Manufacturing. We negotiated access to multiple business and engineering courses in support of our revised curriculum. In addition, we created five courses in direct support of the Advanced Manufacturing option. WSE 470 Wood, Forests, and Civilization, a highly successful on-campus course created many years ago by Barb Lachenbruch was re-introduced as an e-campus course. Thirty-six students enrolled for the first offering in Spring 2017. Seri Robinson created two new wood science courses designed around wood turning and completed construction of a new wood turning laboratory. We offered 3796 credit hours of instruction, upfrom 3306 in the previous year.This represents the fourthconsecutive year of increases. How have the results been disseminated to communities of interest?We worked closely with managers and landowners facilitating visits and student and faculty presentations and meetings with the following groups: 1. Collins Products 2. Columbia Forest Products 3. Forest City Trading Group 4. Murphy Company 5. Pankow Foundation 6. Seneca Sawmills 7. Timber Products 8. Universal Forest Products In addition, faculty and students presented atregional and national conferences. What do you plan to do during the next reporting period to accomplish the goals?Our goal for FY2018 isto develop new research vision for WSE and continue our current activities.
Impacts
What was accomplished under these goals?
Lech Muszynski and Mariapaola Riggio served as field experts for an eye-opening massive timber-themed Dean's tour for COF stakeholders and industry partners. The region of focus was central Europe (Venice to Vienna). The agenda included the structural testing labs of the University Trento, 4 CLT plants, a massive timber connection system manufacturer, an integrated massive panel manufacturer, a 3D massive timber fabrication plant and two remarkable massive timber structures. Participants gained an enhanced understanding of the original CLT market. Mariapaola Riggio, together with Andre Barbosa (CoE) are collaborating with architects and engineers, e.g., Thomas Robinson (Lever Architecture), KPFL, Eng., MGA architects, etc., for the evaluation of fundamental performance indicators of mass timber buildings, such as the vibrational performance of CLT floors. Full-scale tests on-site and laboratory tests will give critical information for further standards development. John Nairn's Material Point Method modeling is seeing major adoption in wood products research as well as in other materials. Examples include modeling of: 1) adhesive penetration into wood, 2) geomechanics problems, 3) metals processing, and 4) civil engineering and soil mechanics. Lech Muszynski and Rakesh Gupta assisted by Milo Clauson conducted the first of its kind series of large-scale fire performance tests on CLT floor and wall assemblies "made in USA". One wall assembly passed a 90 minute fire exposure test, two other and all 3 floor assemblies passed a 120 minute fire exposure test. All assemblies were exposed in loaded condition, without any fire protection ("nacked"), and had an unprotected half-lap joint along the loaded direction. The results are great news for American CLT manufacturers, as well as for architects and engineers interested in building with CLT technology. The fire test reports are available to the public. The OSU team also included Neil Osborn (GRA) and Mr. Milos Pavelek (international visiting PhD candidate from the Technical University in Prague, Czech Republic, hosted by Rakesh and Lech). Chris Knowles' work with the North American Wholesale Lumber Association (NAWLA) is helping to train forest products industry professionals. He is teaming with NAWLA to develop educational content for professionals at all stages of their careers in order to increase their capacity and productivity. Since 2004 the NAWLA Wood Basics course has educated nearly 500 industry professionals. Scott Leavengood has now conducted several on-site quality control workshops for Oregon wood products companies. These workshops involve two days in a classroom with a mix of lecture and hands-on exercises as well as involving participants in the collection of data (e.g., lumber sizes) in the mill followed by analysis and discussion of the results. One participant this year stated, "The sawing variation lesson at last year's workshop was huge for me. We are applying this and it provides us with great insight. As a result...we have eliminated a major concern with our customers." Seri Robinson is blurring the linesbetween art and science with her spalting fungal pigments. Her grant with the Walmart Foundation explores the use of the pigments as textile dyes in inkjet printers, and her new NSF grant looks at using the pigments as thin films in solar cells. Meanwhile, she continues to explore the function and use of spalting fungal pigments in historic and modern woodworking. Rakesh Gupta's project on practical methods for light-frame modular structures is helping Modern Building Systems of Aumsville, Oregon. With wind loads being a major contributor to annual structural damage of light-framed wood structures and a need for methods to sufficiently evaluate load paths, this study is an important development in the design of modular buildings and their acceptance by building code officials. Kaichang Li's group has developed several novel pressure sensitive adhesives using renewable materials. The adhesives are environmentally friendly, easy to produce, and cost-competitive with petrochemical-based pressure sensitive adhesives, and are being commercialized. Patents were issued in the US and many other countries. Fred Kamke assisted in defining manufacturing requirements for Formology Inc. to start up a new custom particleboard facility in Hubbard Oregon. WSE provided all pilot-plant work and product evaluation. The plant is in the equipment acquisition stage and the small facility should create five Oregon jobs. Fred also assisted EcoPro Polymers in establishing a relationship with Formology Inc. to exclusively use their adhesive system. Two years of work with EcoPro resulted in development of a formaldehyde-free adhesive system. Much of this work was funded by Oregon BEST. Fred Kamke created a solution for Dooley Lumber Company (California) to reduce bleed defect in redwood lumber products, positively impacting one million dollars in annual sales. John Simonsen's nano-cellulose-based food coatings technology is being evaluated by Fiberlean Technologies with the intent of commercialization. Their goal is to have products ready for market introduction by the end of 2017. Ari Sinha, Scott Leavengood, and Jeff Morrell's work on design values will mean inclusion of juniper in the National Design Specification, engineers and architects will be willing to specify it for a multitude of applications paving the way for it to be used in non-structural as well as landscaping purposes in government-funded projects. Enhanced utilization of juniper will have direct economic impacts for rural communities in eastern Oregon. Testing coordinated by Ari Sinha has generated considerable excitement within the industry. Testing for Freres Lumber Inc. helped lead to the company's decision to invest millions of dollars in infrastructure to produce mass plywood panels. This investment will lead to job creation and economic development. Testing for the Framework project led to acceptance of the designs by the City of Portland. Similarly, he helped Powerbuild systems to achieve ICC certification or code compliance. This new connection system can revolutionize mass timber construction. A building in Sandy, OR has been built using this new connection system. Ari Sinha continued research in thermal degradation of materials and expanding it to connections. This is critical for fire endurance models for wood structures. Fire endurance structural models exist but data on wood for these models is non-existent. Two publications in 2016 provide preliminary data for connections that led to an ARS proposal on this topic.
