Provisional Syllabus: |
Please provide a provisional syllabus for new courses
and courses in which changes in content and/or description and/or credits are proposed that include the following information:
course goals and description; format/structure of the course (proposed number of instructor contact hours per week, student
workload effort per week, etc.); topics to be covered; scope and nature of assigned readings (texts, authors, frequency, amount
per week); required course assignments; nature of any student projects; and how students will be evaluated.
The University policy on credits is found under Section 4A of "Standards for Semester Conversion" at http://www.fpd.finop.umn.edu/groups/senate/documents/policy/semestercon.html . Provisional course syllabus information will be retained in this system until new syllabus information is entered with the next major course modification, This provisional course syllabus information may not correspond to the course as offered in a particular semester. New: BBE 4404: BIO-BASED COMPOSITES ENGINEERING 3 Credits; Fall Semester Course Syllabus Lectures: Tue, Thu: 10:15-11:30 am in 302 Kaufert Lab Instructor: William Tai Yin Tze ¿ 206 Kaufert Lab; wtze@umn.edu; 612-6242383 Course Description The class provides students with a fundamental understanding of the engineering of bio-based composites and the properties of the composite materials. Students will learn about the use of renewable bio-based resources for composites, including adhesive-bonded laminated veneer composites (e.g. plywood), thermally consolidated particle composites (e.g. strandboard and particleboard), thermoplastic matrix composites (e.g. wood-plastic composites), and bio-nanocomposites. Students will learn the design and processing aspects of bio-based composites by taking into consideration the unique structure and material properties of wood and biofibers. Using principles of polymer science, mechanics, and adhesion, students will learn to engineer and predict properties of various bio-based composites. In addition to lecture, students will undertake a special project on the design, making, and property testing of bio-based composites. Students¿ Learning Outcome Upon successful completion of the class, students are expected to advance towards attaining the following Student Learning Outcomes in which they 1.

Evaluation and Grading: Class will meet together with BBE5404, students of which will be given extra homework assignment and also one different question in the exam. The assessment methods and their respective contributions to the final grade are as follows: 3 Exams @ 20% each: 60% Homework &/or quizzes: 25% Special project: 15% Note: During the course, samples of student works (homework, exams, reports, etc.) will be collected and used for the purpose of evaluation and program accreditation. Student names and ID numbers will be blacked off from copies of sample works to ensure anonymity. Necessary Materials: Scientific calculator References: Bodig, Jozsef and Benjamin A. Jayne, 1993.
