After receiving my bachelor degree in Mechanical Engineering from Bradley University, I started working for Boeing. While at Boeing I worked to receive my master's degree in Mechanical Engineering with an emphasis in Materials and Manufacturing. After leaving Boeing I spent several years in equipment research and development at Starbucks Coffee Company.

From there I decided my heart lied in teaching and left Starbucks to teach Materials Science Technology at Edmonds Community College. I eventually moved to Western Washington University where I have been faculty in the Plastics and Composites Engineering Program (formerly Plastics Engineering Technology) for the past 10 years. My research interests are in composite manufacturing.

Developing a Lab Scale Solvent-Based Prepreg TreaterA lab scale continuous process solvent-based prepreg manufacturing machine (prepreg treater) isa useful tool for small-scale production runs carried out by research teams involved in variousprojects related to advanced composites. Such a machine can also be used in school laboratoriesfor teaching purposes. However, industrial compact prepreg treaters available for purchase arevery expensive. This document details the work done by undergraduate students at WesternWashington University to design, develop, and qualify a modestly budgeted, solvent-basedprepreg manufacturing machine to be used for investigation of new prepreg resin systems. Thesteps undertaken to manufacture the machine and qualify it are explained in detail and can behelpful to educational institutions that may have requirements of such a treater for researchand/or teaching.
