MARR 124 - Introduction to Composite Technology

• Prerequisite: MARR 122

This course covers the fundamentals of working with resins, fabrics, and adhesives. Projects include the fabrication of solid and cored test panels. The methods used to insure quality control in the composites industry are also stressed. Classroom instruction and tasks performed will be in accordance with applicable American Boat and Yacht Council (ABYC) Standards and industry best practices. Students successfully completing this course will be able to sit for the ABYC "FRP (Fiberglass Reinforced Plastics) Composites for Technicians" certification examination.

(9O hrs. lect./lab. per term)

Student Learning Outcomes

Upon successful completion of MARR 124, the student will be able to:

• Demonstrate ability to safely handle hazardous materials
• State the practical principals of polyester and epoxy resin chemistry
• Utilize the principal of specific gravity to perform weight to volume conversions for accurate mixing of components
• Create a shop catalyzation chart from a resin's product data sheet indicating minimum and maximum catalyst levels in cubic centimeters
• Properly catalyze resins and add various components (fillers, promoters) to polyester/epoxy resins for differing applications and working conditions
• Perform gel-time, peak exotherm test, and Barcol hardness tests on resin samples for quality control
• Identify composite fabrics and state when and why a certain fabric should be utilized
• Laminate test composite panels and perform weight calculations.
