Introduction for learning composites:
A learning composite material may be defined as a material system consisting a mixture of two or more micro-constituents, which are mutually insoluble, differing in form or composition and forming distinct phases. Such a combination possesses properties different from those of any of its constituents. Example: Fibres, particulates, flakes and whiskers.
Types of composites
There are three types of learning composites:
Polymer composites:
In learning composites, the fiber reinforced polymer composites constitute more than 90% (by weight) of the total composites used in various industries. The advantage of using polymer in structural composites is the ease of fabrication of complex structural shapes. It can be easily manufactured.
Fiber-reinforced plastic are produced by suitably bonding a fiber material with a resin matrix and curing them under pressure and heat. The main reinforcing agents used in FRP composites are alumina, glass, boron, graphite, carbon, etc. the reinforcement material can be in different forms such as short fibers, continuous filaments or woven fabrics.
The resin matrix commonly used in FRP polyesters, epoxy, phenolic, silicone and poylamide polymer resins.
Understanding Cobalt Isotopes is always challenging for me but thanks to all math help websites to help me out.
Metal matrix composites
In learning composites, metal matrix composites exhibit extremely good thermal stability, high strength, good stiffness and low specific weight.
MMCs also have other advantages like fracture toughness, ductility and enhanced performance at elevated temperature.
They can withstand at elevated temperatures in corrosive environment than polymer composites.
They are used in engine blades, combustion chamber, etc.
Al and Mg MMCs are used in automotive industry.
They improve fuel efficiency because of the weight reduction.
Ceramic matrix composite
In learning composites, CMCs are used at temperatures above 1500 degree Celsius because of their good corrosion resistance, stability at elevated temperatures and high compressive strength.
Ceramics provide necessary strength at high temperature with good oxidation resistance.
The matrixes used are glass, ceramics, carbides, nitrides, oxides and borides, the reinforcements are Al2O3, B, C, SiC and SiO2.
Advantages of composites
They possess higher specific strength and lower specific gravity.
They possess lower electrical conductivity and thermal expansion.
They possess better creep, fatigue strength, corrosion, and oxidation resistance.
They maintain very good strength, even up to high temperature.
