Description

The Composites Knowledge Network (CKN) in partnership with SAMPE Canada is hosting a series of 12 one-hour long webinars on composite materials engineering.

Session 7: Manufacturing Processes: Liquid Composite Moulding (August 5, 2020 @ 9:00 am PST)

Liquid composite moulding is a family of processes that involve saturating dry fiber reinforcement with a a pressure differential in the mould. Common processes include vacuum infusion (vacuum assisted resin transfer moulding (VARTM)), resin transfer moulding (RTM), and light resin transfer moulding (LRTM). This session will layout the fundamental differences in the aforementioned processes, and when and where each process is applicable. We will then introduce resin flow theory based on Darcy’s law and a procedure for process design.


Instructor: Casey Keulen, PhD (Instructor, Materials Engineering, University of British Columbia).

Registration and Inquiries: Please e-mail Suzana Topic: suzana@composites.ubc.ca.

Cost: This complimentary workshop is funded by the Composites Knowledge Network (www.compositeskn.org).


This webinar series was developed to bring the participants to an intermediate level of composite materials understanding. It is intended for junior to senior engineers that are looking for a solid background in the fundamentals of composites to help make both engineering and business decisions. After completing this series, the participant should have the skills to identity suitable applications of composites, select materials and processes, estimate composite mechanical properties, and identify appropriate testing procedures.

The topics will cover a wide range of aspects of polymer matrix composites from both a processing and analysis perspective. It will start with a general introduction to composite materials, then discussion of constituent materials like fiber and resin, before going into thermal management of manufacturing processes (curing a resin). With that knowledge established, various processing methods will be discussed, with a deeper look into prepreg processing and liquid composite moulding (ie. vacuum infusion, resin transfer moulding, etc.). After that, the focus will be on the mechanics of composites. What is happening on the lamina and laminate levels, and eventually failure of composites will be covered. The last two sessions will tie the processing sessions and mechanics sessions together with a discussion of testing.
