Composite structures and case study

Presentation

A general course (16.25 h) to the whole group is given on laminate theory and technos. A handout deals with simple and more complex issues of composite theories. A general presentation deals on technos.

Organization:

• A project on an aeronautic case study is done within 6 courses of 3h each and deals with basic static sizing, damage tolerance design and manufacturing. 
• The project is done by pair under the supervision of academic or senior engineer.
• 6h of CATIA Composite are also done to study practical composite design rules of aeronautic industry.
• Two practical works of 3h each enables to manufacture composite plates by hand stacking or LRI.

Objectives

Main Objectives :

The student will be able to perform simple sizing of composite structures and to choice a couple manufacturing/material for a given case study.

The student will be able to:

• Choice a couple of fibers and matrix and their commercial products.
• Choice a type of composite structure: laminates, sandwichs, 2D1/2,3D, 4D.
• Determine the manufacturing method: hand layup,  fiber placement, RTM, LRI, RFI.
• To be inspired by solutions of automotive, naval, wind energy or aerospace industry.
• To be inspired by past experience in aeronautic industry.
• Know and use laminate theory.  
• Knows and use simple sizing of junctions.
• Know issues of impact and ageing.
• Know issues of failure and damage.
• Realize a case study : example wing box of an acrobatic aircraft.
• Make a presentation of their sizing and their design.
• Work in a collaborative manner.

Needed prerequisite

- Beam theory, Continuum mechanics, Materials behaviors.
- Matrix calculation.

Form of assessment

The evaluation of outcome prior learning is made as a continuous training during the semester. According ot the teaching, the assessment will be different: as a written exam, an oral exam, a record, a written report, peers review...
