What are the properties of polymers?

What are the properties of polymers?

Some of the useful properties of various engineering polymers are high strength or modulus to weight ratios (light weight but comparatively stiff and strong), toughness, resilience, resistance to corrosion, lack of conductivity (heat and electrical), color, transparency, processing, and low cost.

What are the 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 properties of polymers describe the classification of polymers with examples?

The most common way of classifying polymers is to separate them into three groups – thermoplastics, thermosets, and elastomers. The thermoplastics can be divided into two types – those that are crystalline and those that are amorphous.

What are the properties of synthetic polymers?

2.1. 1 Introduction to various classes of synthetic polymers

Polymer Key properties
Poly(propylene) Linear thermoplastic Tough, flexible with good fatigue resistance
Poly(methyl methacrylate) Lightweight transparent thermoplastic, good impact strength, poor resistance to chemicals

Why do polymers have different properties?

Because of the structure of the molecules, polymeric materials have different properties compared to other materials, like metals. Specifically, the relatively high molecular weight and long polymer chain length result in entanglement, and the lack of covalent intermolecular bonds facilitates polymer chain mobility.

What are the properties of composite materials?

What are the types properties and application of composites?

A composite material is a combination of two materials with different physical and chemical properties. When they are combined they create a material which is specialised to do a certain job, for instance to become stronger, lighter or resistant to electricity. They can also improve strength and stiffness.

What are the three general factors that determine the properties of a composite material?

Answer. Three factors are given in the text: (1) the component materials; (2) the geometric shapes of the constituents – the reinforcing phase in particular – and the resulting structure of the material; and (3) the interaction of the phases.
