The Wood-Based Composite Science Short Course series, developed in partnership with the Oregon Wood Innovation Center and the Wood-Based Composites Center, provides mill operators as well as career professionals with a fundamental knowledge of wood as an engineering material in the manufacturing of wood-based composites. If you complete the series, you may be eligible for a Certificate of Completion and will be able to improve manufacturing efficiency and product performance, troubleshoot processing problems and enhance your value as an employee.

 

Wood science and technology experts, selected from top universities, government research labs and industry, teach the course's six modules.

  • Wood Structure.

    Instructor: Fred Kamke (Oregon State University; fred.kamke@oregonstate.edu)
    This course introduces the macro- and micro-structure of wood. It focuses on the practical implications of anatomical structure in the field of wood-based composites. Many wood species are discussed, but limited to species of commercial importance in North America. Examples include species that are commonly used in the manufacture of wood-based composites. Many photomicrographs and animations are used to illustrate concepts. Anatomical features of wood are discussed in relation to wood properties, such as density, permeability, and bending modulus. Understanding how and why wood behaves the way that it does is critical for efficient processing, troubleshooting, and product performance

  • Wood and Water Relationships.

    Instructor: Scott Leavengood (Oregon State University; scott.leavengood@oregonstate.edu)
    This course describes the interactions of wood and water and the effect on a number of properties – shrinking and swelling in particular. The course begins with lectures on gas behavior and humidity. This information serves as background for understanding interactions between temperature and humidity, and their impact on wood behavior. The information on wood and water relations is divided into two lectures. The first presents a review of wood structure, how wood holds water, how we calculate moisture content, why wood shrinks and swells, and how wood’s moisture content changes with changes in temperature and humidity. The second lecture on wood and water relations focuses on shrinking and swelling. Solid wood is presented first followed by unique issues with composite wood products such as restraint due to cross-lamination, the impact of densification, and variability in density. The course also includes information on common methods and tools used for measuring moisture content.

  • Applied Statistics and Data Analysis.

    Instructors: Chris Knowles (Oregon State University; chris.knowles@oregonstate.edu) and William Boehner (formerly Weyerhaeuser Company; Oregon State University; awilliamboehner@cableone.net)
    This course introduces students to applied statistics and data analysis with a focus on the practical implications of statistics in the field of wood-based composites. The course will prepare the student to collect and analyze data using basic statistical tools. Students will learn how to compute and interpret basic descriptive statistics such as mean and standard deviation. Students will also learn how to compare means from different samples using t-tests and ANOVA and how to interpret the results of those tests. Understanding how and why to collect data and analyze data is critical for quality control, troubleshooting, and product performance.

  • Strand-based Composite Manufacturing.

    Instructor: William (Bill) Boehner (formerly Weyerhaeuser Company; Oregon State University; awilliamboehner@cableone.net)
    This course covers the manufacturing of strand-based composites (OSB and LSL) beginning in the forest and continuing through pressing as outlined below. Within each lecture, key variables that affect the quality of the intermediate product, such as a strand, as well as the finished panel product are identified and discussed. Results of scientific studies and a mill trial are presented to support conclusions.

  • Practical Wood Adhesives Technology 

    Instructor: Bruce Broline (formerly Arclin; Oregon State University; bruce@brolineconsulting.com)
    Course goals are to develop an understanding of basic chemistry of resins, resin manufacturing, resin options for wood bonding, practical aspects of resin use, resin performance, green aspects of resins, improve effectiveness for solving production problems, and facilitate working with resin suppliers. No knowledge of chemistry is assumed. Any chemical principles required for this course will be discussed.
