Polymer Composite Materials and Additive Manufacturing (SPbPU - MAI joint program)
International Polytechnic Summer School 2024 will be held on campus.
- Brief description
Polymer composites have high strength, lightness, and good thermal and acoustic properties, making them ideal for use in a variety of industries, including aviation, automotive, and construction. In the first part of our summer school, based at MAI, we will introduce you to the main types of binders and fillers used in composite materials, and talk about their advantages and disadvantages. The program of the first module will be full of interactive classes, laboratory workshops and visits to the real production, where aircraft structures from PCM are manufactured.
In the second module, on the basis of SPbPU, you will get acquainted with additive manufacturing, which is increasingly used in a variety of industries. In this module, you will learn about production methods and characteristics of powder materials, get acquainted with various technologies of additive manufacturing, including the technology of electric arc additive manufacturing from wire. One of the most serious problems in the field of additive technologies is the problem of joining the printed parts into a single, complete structure. This joining must meet a large number of requirements, including preservation of the unique microstructure and properties obtained during growth. To solve these problems, methods of joining materials in the solid state, in particular, friction stir welding, are mainly used, which we will introduce you to.
Career Opportunities: This is more than just a course - it's the key to a future in engineering, materials science, design and other related industries. Gain valuable experience and knowledge that will become your competitive advantage.
Duration: 2 weeks
First week will be held at Moscow Aviation Institute. Second week will be held at Peter the Great St.Petersburg Polytechnic University.
ECTS credits: 4.0
Participation fee: 1450 USD
Upon successful completion of the course students will receive hard copies of certificates with ECTS credits (mailed by post in case of the online format of the Summer School).
