Outline

Chapter 1. Introduction to Composite Materials

1. Overview of full composite structures around Europe
2. Materials (Types of fibers and matrices)
3. Manufacturing processes (Hand Lay-Up, Prepreg Lay-Up, Bag Molding, Autoclave Processing, Pultrusion, Filament Winding)
4. Nomenclature and standards

Chapter 2. Micromechanics

1. Representative Volume Element (RVE)
2. Composite Materials from a constitutive point of view (from anisotropic to isotropic material)
3. Stiffness and strength (along longitudinal and transverse direction with respect to fiber orientation, inplane shear and strength)

Chapter 3. Macromechanics

1. Plate stiffness and compliance
2. Common laminate types (laminate description; symmetric, antisymmetric, balanced, quasi-isotropic; cross-ply, angle-ply, specially orthotropic laminates)

Chapter 4. Failure and strength design

1. Failure criteria
2. Laminate strength

Chapter 5. Beams

1. Preliminary design (Deflection, Strength, buckling)
2. Thin walled beams

Chapter 6. Applications and Standards

1. Full composite structures: connection types between GFRP pultruded profiles (draft of the Technical Specification “Design of fibre-polymer composite structures” CEN TC/250)

Note: From Chapter 1 to 5 reference from the book titled Introduction to Composite Materials Design (Taylor and Francis) by EJ Barbero. For Chapter 6 the Lecture Notes will be given to the students.
