Composite structures and case study


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.



  • 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.


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...
