Properties of Composite Material and Their Application

14:51 Wed 15th Sep 2021 |

A composite material is made up of two components that have distinct mechanical and molecular qualities. When they're combined, they make a product that's tailored to a particular project. For instance, composite decking boards manufactured in Europe are tougher, lightweight, and more resistant to weather elements while also possessing features of durability and rigidity.

Although the components function in unison, they do not disintegrate or entirely melt into each other inside the composite.

We will study composite materials, their properties, application, and many more in this article.

Composites: An Overview

Due to their versatility to a wide range of conditions, composite materials are possibly the most widely utilised materials.

It is simple to blend with various materials and has desirable qualities to perform certain functions.

The composite materials have a higher hardness and wear resistance than bulk materials while having a lower density.

Composite materials have the following properties:

  • -Wooden Composite materials have a structural integrity that is 4-6 times that of traditional materials like timber wood.
  • -They have better torsional stiffness and are more resilient.
  • -It can withstand a lot of strain (ultimate tensile strength of up to 60 per cent).
  • -They are 30–45 per cent lighter than aluminium structures that provide the same functions.
  • -Has minimal integrated energy.
  • -Composites produce lower noise levels during operation.

Application of composite materials

Trains:

Composites are increasingly being employed in the railway sector, with savings of up to 50percent in terms of structural applications and up to 75% for non-structural usage at incredible velocities, power efficiency, reduced friction & track wear, and the ability to carry larger loads.

Composites, which also withstand rust and have great performance, are now being used for a growing number of components.

Bridge:

The bridge has foot, bike, and motorcycle crossings that stretch on a set of rail tracks.

Frames for doors and windows:

Base materials like flexible polystyrene foam, expanded polystyrene, and sheet honeycomb are bonded between fibre-reinforced plastic to make doors.

These materials could be used in residential structures, workplaces, classrooms, clinics, factories, and a variety of other settings.

Smart concrete:

Smart concrete, in contrast to traditional concrete, has improved potential and strength.

Smart concrete can be made by including carbon fibre for electromagnetic insulation and greater electrical conductivity.

The smart concrete will release and recover its conductivity during the loading/unloading process, functioning as a building material and a sensor.

Smart concrete is important in pavement design construction because it acts as a traffic-sensitive sensor and dissolves snow throughout the winter owing to the reduced voltage level.

Retrofitting and Rehabilitation:

The material is frequently linked mechanically to the structure in the manner of tow (microfibre spools), clothes, sheets, stirrups, and outerwear.

Composites in this category can bond well with a variety of base materials and stick to intricate shapes.

Decking materials:

All composite decking is manufactured from a mix of wood fibres and polymer, resulting in a strong and long-lasting decking product.

High-performance composite decking boards are manufactured with 55 per cent reclaimed timber materials and 45 per cent high recycled polymers, a plastic derived primarily from disposable milk jugs.

Our composite decking boards are not only produced from sustainably sourced materials, but they are also good for the environment, as they include no PVC or harmful particles that could seep into your lawn or home exterior.

Advantages of composite materials

Composite materials have the following advantages:

  • -They have a minimum density and are extremely lightweight.
  • -It has a strong resistance to creep.
  • -Has superior fatigue characteristics than those of standard engineering materials.
  • -Unlike steel, composite materials are slow to corrosion.
  • -There is the possibility of incorporating sensors into smart composite materials to track their performance.
  • -They have a high level of resistance to weather damage.

Disadvantages of composite materials:

Composite materials have the following drawbacks:

  • -It has an exorbitant raw material and manufacturing cost.
  • -Because the matrix is feeble, there isn't much toughness.
  • -Most composite material will be tough to reuse and dispose of.
  • -Instable prices or costs

Conclusion

Because composite materials offer superior mechanical, structural, and molecular qualities, they can be used in a wide range of industries.

As a result of their desirable qualities, composite materials are used extensively in the building and construction sector.
