. Additionally, wronganswers were not accepted. Students had to get their pre-labs checked in face-to-face meetingswith the instructor and anything that was incorrect had to be re-done and re-checked prior toreceiving a grade. The grade was based solely on when the student was able to get it all correctand checked. The post-labs became just a matter of filling in a spreadsheet that was created inthe pre-lab and answering a few questions. The post-labs were graded during class. Studentsstayed in class for most, if not all, of the class period.

Prepreg Treater OverviewThe prepreg treater can be broken into 4 major sections: the unwind/bath, ovens, ventilation andtake-up, as shown in Figure 1. In the bath section of the machine, fabric is unwound from a roll,dipped into the resin bath and then threaded between two pinch rollers to remove excess resin.From there, the resin-coated fabric is conveyed into the oven section of the machine, where thematerial is "B-staged". During B-staging, the material is partially cured and solvent is removed,necessitating the use of a ventilation
