Exploration of paper product behavior from a materials science perspective. Fundamental laws of physics, both deterministic and statistical, will be used to explain experimental results. Discusses and analyzes theoretical models to explain paper behavior. Prerequisite: PSE 248; PHYS 121, 122, 123. Offered: A.
Course Objectives: 1. Develop an awareness and an understanding of the major topics in paper physics 2. Explore in depth a topic in paper physics that is not well understood (or which is controversial)
This course is currently being revised. A new thematic approach is being taken. Rather than construct the logical flow of topics and ideas from a mass flow point of view, i.e. raw material, manufacturing processes, product and end-uses, an opposing direction information flow point of view will be taken. What are the performance charateristics of the end-uses of the product? What are the quality control measures that are related to the performance characteristics? How are the quality control measures related to variables that reflect process changes? And how are the raw material characteristics changed by the processes? In this way, it may be possible to make sense out of the myrad of empirical tests that are used to assess the quality of paper.
Student learning goals
General method of instruction
Wood and fiber characteristics. Some elementary understanding of the pulp manufacturing and paper making process. Basic math and physics concepts particularly mechanics, wood/water relationships and optics. (Some review of this material will be given in the couse itself.)
