Are two important classes of materials with wide-ranging applications in various industries.
Polymeric Materials:
Are composed of long chains of repeating units called polymers. These polymers are made up of smaller units called monomers, which are covalently bonded together. The properties of polymeric materials depend on factors like the type of monomers, their arrangement, and the processing methods used. Common examples of polymeric materials include plastics like polyethylene, polypropylene, PVC (polyvinyl chloride), and polymers like nylon, polyester, and polyurethane.
Properties: Lightweight and flexible, insulating, Chemical Resistance...
Applications: Packaging, Automotive, Medical, Construction...
Processing Techniques: Extrusion, Injection Molding, Compression Molding...
Composite Materials:
Are composed of two or more distinct phases, typically a matrix material and a reinforcement material. The combination of these materials results in a material with improved properties compared to its individual components. Example:
Fiber-Reinforced Composites: Such as carbon fiber reinforced polymers (CFRP) or glass fiber reinforced polymers (GFRP)
Metal Matrix Composites (MMC): Aluminum reinforced with silicon carbide
Ceramic Matrix Composites (CMC): Silicon carbide fibers in a silicon carbide matrix
Properties: High Strength-to-Weight Ratio, Tailorable Properties, Anisotropic...
Applications:
Aerospace: Composites are extensively used in aircraft for components like wings, fuselage, and interior panels
Automotive: Especially in high-performance or specialized vehicles
Sports Equipment: Bicycles, tennis rackets, and helmets often incorporate composite materials
Construction: Used in bridges, reinforcement bars, and other structural elements
Manufacturing Methods: Lay-Up Process, Filament Winding, Resin Transfer Molding (RTM), Autoclave Molding...
