(*Please contact Abaris for equivalency test criteria and evaluation.)

Summary:

This course is designed for the engineer, technician, laminator, fabricator, or anyone else wanting to learn about the fundamental principles and more complex concepts involved in resin infusion technology.

Introduction:

Previous experience with composite materials, layup, and vacuum bag processing is required. For those who do not have a thorough background with advanced composite layup and processing, we recommend our M1/R-1 Composite Structures: Fabrication & Damage Repair-Phase 1 course as a prerequisite course prior to attending the resin infusion course.

The fundamental science that drives vacuum infusion processing (VIP) is explained and tested in the workshop. Materials, tooling and application techniques are evaluated and applied with hands-on exercises and demonstrations. Students will gain a theoretical understanding and practical hands-on experience necessary to employ vacuum resin infusion in their own applications.

This course will examine the pros and cons of infusion processing and define the usefulness and limitations related to the VIP process. The class includes a basic overview of the necessary facilities and equipment required to set up and perform VIP in a production setting.
