What are the material properties of bone?

Bone is a composite of proteins such as collagen and minerals such as calcium. Together these materials give bone a unique combination of strength and elasticity.

What are the mechanical properties of composite materials?

Fundamental features of composite materials are high strength, light weight, fatigue resistance, high stiffness, fire resistance, flexibility and thermal resistance.

What are the most important mechanical properties of composites?

However, as a class of materials, composites tend to have the following characteristics: high strength; high modulus; low density; excellent resistance to fatigue, creep, creep rupture, corrosion, and wear; and low coefficient of ther- mal expansion (CTE).

What are the most important mechanical properties of bone?

Early research on the microstructural and compositional factors that control the mechanical properties of cortical bone focused largely on porosity and mineralization. Cortical porosity is negatively correlated with Young’s modulus (42), compressive ultimate stress (43), and fracture toughness (44).

Is bone an anisotropic material?

1. Basic material properties. The material behavior of cortical bone is anisotropic. The strength and tensile/compressive moduli of cortical bone along the longitudinal direction (the direction aligned with the diaphyseal axis) are greater than those along the radial and circumferential directions (Table 1).

What are mechanical properties?

Mechanical properties are physical properties that a material exhibits upon the application of forces. Examples of mechanical properties are the modulus of elasticity, tensile strength, elongation, hardness and fatigue limit.

What are the types properties and application of composites?

Metal matrix composite: A metal spread throughout a matrix. Reinforced concrete: Concrete strengthened by a material with high tensile strength such as steel reinforcing bars. Glass fibre reinforced concrete: Concrete which is poured into a glass fibre structure with high zirconia content.

What are the 3 different types of fiber reinforced composites?

Fiber reinforced composites can be classified into four groups according to their matrices: metal matrix composites (MMCs), ceramic matrix composites (CMCs), carbon/carbon composites (C/C), and polymer matrix composites (PMCs) or polymeric composites (Fig. 3.10).

What is structure of bone?

Compact bone consists of closely packed osteons or haversian systems. The osteon consists of a central canal called the osteonic (haversian) canal, which is surrounded by concentric rings (lamellae) of matrix. Between the rings of matrix, the bone cells (osteocytes) are located in spaces called lacunae.

What are the four components of bone?

The skeletal system includes four basic components, although some sources include a fifth, the joints. The four are the bones, which make up most of the mass of the skeletal system; cartilage, which acts mainly as padding; ligaments, which usually connect bones to bones; and tendons, which join muscles to bones.
