Course Description:
This is a three-credit lecture-based course on the renewable bioproducts for light weight energy efficient building and other structural applications and the manufacturing processes of these products. These renewable bioproducts are consisted of engineered wood products (EWPs), including structural panels, structural composite lumber, glued laminated timber (Glulam), wood I-joist, and etc., and the natural fiber reinforced polymer composites, such as wood plastic composites (WPC), agriculture fiber based polymer composites, and etc. The characteristics of the biobased raw materials, such as wood, agricultural fiber, biobased resins and polymers will be discussed in the class. The manufacturing processes of the renewable biocomposites include: lamination, mat-forming, compression molding, extrusion, injection molding, etc. The physical and mechanical behaviors of the composites will be discussed. The students will understand how these engineered renewable biocomposites are designed, processed, and graded; what the pros and cons are for each product as related to the structural applications. Students will learn about the related standards, acceptance criteria, and technical guides on these products. Some application details in construction will be discussed, such as fastener and connection design, fire design, and etc.

2. Understand the major manufacturing processes for wood and biobased composites including the lamination, mat-forming, compression molding, extrusion, etc.
3. Understand the basic adhesion theory and the major adhesives used in the wood and biobased composites fabrications.
4. Understand the basics of material grading in related to the material design, quality assurance and quality control for the composite fabrication, standards and building codes for composites evaluation.
5. Understand the mechanical and physical behaviors of wood and biobased composites
Course Instruction and Assignments
1. Backboard Learn at http://learn.unt.edu and your myunt e-mail address will be used for posting the course materials and instructions, assignments, submission of assignments, email communications about the course, and the course grade-book. Students should ensure that the myunt e-mail is forwarded to an e-mail address that they frequent more often so that communication through e-mail is ensured.
2. Students are required to attend lectures and laboratory classes.
3. Homework will be turned in on the due date.
4. Makeup examination will not be given, and only be administered under extreme circumstances with a documented university excuse.
Exams
1. Class exams and quizzes are written and closed textbook and notebooks unless announced as such.
2. A ruler, laptop and scientific calculator are encouraged for classes, quizzes and exams. Limits or extent of use will be outlined ahead of each exam.
3. Grades are based in part on the student's ability to communicate. You must present your entire solution in an orderly way for each problem. Full grade points will not be assigned only on the final answers with correct steps. You must show the complete process of your solution. Partial credits will be assigned for correct steps that have been taken in a solution.
4. Requests for the review of a graded exam problem must be submitted in writing no later than the next class day following the return of a graded exam. The graded exam should be attached to your request and you must explain your reason for requesting a grade review. In this matter, the review is not limited to a single problem requested by the student. Upon review, the exam score may increase, remain the same, or decrease.
5. An “I” (incomplete) grade is given only for extenuating circumstances and in accordance with University and Departmental Policies.

Term paper:
Every graduate student is required to accomplish a term paper (a minimum of 6 pages, double space). You may choose a topic of your interest early in the semester and discuss with instructor on the topic. It can be a topic either related to the engineering design with the biomaterial, or material treatment to improve a specific performance, or discuss a fabrication process for a certain biocomposite product. A literature review related to your topic is required. The format of the term paper should include: 1. Introduction, 2. Literature review, 3. Methods, 4. Results and Discussion, 5. Conclusions, and 6. References.
