MEGR 2180 omposite materials Composite materials Introduction • Definition: a material composed of 2 or more constituents – Reinforcement phase (Fibers) – Binder phase (compliant matrix) • Advantages – High strength and stiffness – Low weight ratio – Material can be designed in addition to the tructure structure

MEGR 2180 COMPOSITE MATERIALS einforced plastic consist of fibers in a plastic matrix Reinforced plastic consist of fibers in a plastic matrix • Combines the properties of the two materials – Plastic is less strong and stiff but more tough – Fibers are strong and stiff but brittle • The matrix in reinforced plastics has 3 functions – Support and transfer the stress to the fiber (which carry most of the load) – Protect the fibers against physical damage and the environment – Prevent propagation of cracks in the composite (ductility and toughness)
