1 Introduction to Aerospace Engineering Lecture slides Challenge the future 1

2 Material types Metals, polymers, ceramics, composites Faculty of Aerospace Engineering Delft University of Technology Challenge the future

3 Learning objectives Student should be able to Describe the characteristics of typical aerospace materials Describe the groups of different materials Estimate composite material properties based on its constituent properties Material types 2 21

4 Materials Overview of materials Recall Metals/metal alloys Alloying & heat treatments (composition & condition) Polymers Insufficient properties (low strength & stiffness) Ceramics Brittle materials Composites Composed materials (fibres, resin, metals) Material types 3 21

5 Metals Typical applications High strength structures (tension & compression) Aircraft, bridges, towers Components & products (high volume production) Cars, cans, etc Reinforcement Cables Material types 4 21

6 Polymers Typical applications Elastomers Rubbers Plastics Thermoplastic Thermoset Fibres Natural fibres Synthetic fibres Nylon Material types 5 21

7 Polymers Properties Mechanical properties depend on temperature, strain rate & environment Low temperatures Elastic and brittle behaviour Medium temperature Rubbery behaviour Glass transition temperature High temperature Viscous (liquid) E 1 E 2 T g T m Material types 6 21

8 Ceramics Types and properties Ceramics often consist of (metal) oxides and metals Ionic bonds between the different atoms Properties Hard and brittle (limited toughness - small failure strain) High strength and stiffness feasible (depends on composition - porosity) Able to sustain high temperatures (strong bonds) Wear resistant Material types 7 21

9 Ceramics Typical applications Glass Window panes, lenses, fibers,... Clay Porcelain, bricks,... Cements Cement, lime,... Other Cutting tools and abrasive materials Armor reinforcement Heat resistant ( C) materials for engines and space shuttle heat protection system Material types 8 21

10 Ceramics Space Shuttle Columbia Crashed February 1, 2003 Crew of 7 killed During lift-off and mission no apparent problems Explosion during re-entry Material types 9 21

11 Ceramics Space Shuttle Columbia Analysis: Piece of foam detached from tank hits leading edge during lift-off Foam damages heat resistant ceramic skin Importance of heat protection! Material types 10 21

12 Composites Definition Composites are engineering materials in which two or more distinct and structurally complementary substances with different physical or chemical properties are combined to produce structural or functional properties not present in any individual component Material types 11 21

13 Composites Example 1: Fibre reinforced polymer composite Two distinct structurally complement materials: Fibres Function: Reinforcement, carry main portion of load Polymer Functions: Transfer load to/from fibres in shear; protection, support Material types 12 21

14 Composites Properties Properties of fibre reinforced polymers High specific properties (strength and stiffness) Elastic until failure (no ductility) High directionality (anisotropic) - enables tailoring to specific load applications (beams, cables, columns) - requires multiple orientations to cope with bi-axial load applications Material types 13 21

15 Composites Example 2: Hybrid materials Three distinct structurally complement materials: Metal Function: Ductility, isotropic strength/stiffness Fibres Function: Reinforcement, carry significant portion of load Polymer Function: Transfer load between fibres and metal in shear Material types 14 21

16 Composites Elastic property estimation Rule of mixture Simple relations to estimate properties of a composite based on the properties of its constituents Caution: not accurate Example: fibre reinforced polymer composite Total mass = density x volume M = M + M ρ V = ρ V + ρ V FRP F M FRP FRP F F M M Formulated as volume fractions ρ V V F M = ρ + v V ρ V ρ = ρ + ρ FRP F M FRP F F M M FRP FRP v Material types 15 21

17 Composites Elastic property estimation Rule of mixture: density of glass/epoxy composite ρ F Density [kg/m 3] ρ M Fibre volume fraction Material types 16 21

18 Composites Elastic property estimation Rule of mixture example: Tensile modulus (T300 carbon fibre) Tensile modulus (GPa) UD Bi-axial Quasi-isotropic ~factor Fibre volume fraction Al-alloys Material types 17 21

19 Composites Elastic property estimation Rule of mixture example: Fibre Metal Laminate Metal sheet FML Composite Fibres Matrix See previous slides Metal volume fraction v M ( ) S = S v + S v = S v + S 1- v FML M M FRP FRP M M FRP M Material types 18 21

20 Composites Properties Material Specific strength Failure strain Electrical conductivity Flame resistance UV resistance Chemical resistance Glass fibre reinforced composite High Medium Low High High Low Carbon fibre reinforced High Low High High High Low composite Aramid fibre reinforced High Medium Low High High Low composite Fibre Metal Laminate High Medium High High High Medium Material types 19 21

21 Composites Typical applications Glass fibre composites Wind turbine blades, sail planes, pressure tanks & vessels, etc. Carbon fibre composites Automotive, aerospace, sailboats, (motor) bikes, sport equipment, etc. Aramid/kevlar composites Armor & bullet proof products, etc. FMLs Aerospace Material types 20 21

22 Summary Material types Typical aerospace materials are Metals Polymers Ceramics Composites With their own characteristic properties and applications Material types 21 21
