An artificially prepared or natural multiphase material that exhibits a significant properties of the both the constituent material
Composites
Materials made from two or more constituent materials with significantly different physical or chemical properties
Phases of composites
Matrix phase
Reinforcement phase
Interphase
Matrix phase
The continuous or binder material that surrounds and holds together the reinforcement material, provides support to the reinforcement
Reinforcement phase
Fibers, particles, or other materials embedded within the matrix
Interphase
The region where the matrix and reinforcement phases interact, a crucial area that influences the overall performance, mechanical properties
Types of composites
Fiber-reinforced composites
Particle-reinforced composites
Structural-reinforced composites
Fiber-reinforced composites
Characterized by the use of fibers as the primary reinforcement within a matrix material, fibers can be continuous or discontinuous
Particle-reinforced composites
Involve the dispersion of particles within a matrix material, particles can be of various materials, including ceramics, metals, or polymers
Structural-reinforced composites
Designed for load-bearing applications where high strength and stiffness are critical, often combine different types of reinforcements to achieve specific mechanical properties
Differences between fiber and plastic
Composition
Properties
Application
Environmental Impact
Recycling and sustainability
Plastic
Can exhibit a wide range of properties depending on factors such as the type of polymer, additives
Fiber
Characterized by their high length-to-diameter ratio, which gives them unique mechanical properties such as high tensile strength, flexibility, and elasticity
Metal
Comprised of elemental atoms or alloys, which are combinations of two or more metallic elements, have distinctive physical properties
Concrete
A composite material made up of several components, the main constituents include aggregates (such as gravel, sand, or crushed stone), cement (commonly Portland cement), water, and sometimes supplementary materials
Fiber composites
A class of advanced materials that utilize fibers as the primary reinforcement within a matrix, find applications in aerospace for lightweight and high-strength components like aircraft wings
Components of Composite Fibers
Matrix materials
Reinforcing fibers
Matrix materials
The matrix functions similarly to glue in composite materials, it is a solid substance that keeps things together
Types of matrix materials
Ceramic Matrix
Metal Matrix
Polymer Matrix
Ceramic Matrix
Ceramic-based materials, they resemble a mixture of ceramic fibers
Metal Matrix
Unique materials composed of metal blended with something else, such as another metal or another substance
Polymer Matrix
A polymer is a large molecule composed of smaller pieces held together by strong connections
Reinforcing fibers
Very small threads formed of glass, carbon, or aramid
Types of reinforcing fibers
Carbon Fibers
Glass Fibers
Aramid Fibers
Carbon Fibers
A plastic-based substance, sometimes called graphite fiber, extremely strong but weighs very little, five times stronger than steel and twice as firm
Glass Fibers
Fiberglass is a durable material that contains small pieces of glass, glass fibers can be manufactured from a variety of glass types depending on their intended application
Aramid Fibers
Artificial fibers designed to be extremely strong, particularly when tugged, known for their tremendous strength, used in high-end products that require both lightweight and extreme durability
