... providing long lasting & new age “GREEN” solution to ageing Infrastructure.
Composites are materials that are made up of at least two different component materials, of which neither are well suited for construction purposes on their own, but the combination result in a very sturdy and firm material.
Composites can be generally divided into two groups
- Synthetic materials reinforced with short fibres
- Synthetic materials reinforced with long (continual) fibres
In fibre-reinforced plastic materials, the characteristics of fibres are used to resist tensile and compressive loads, while the plastic – the matrix material – transfers shear.
Because it is a combination of materials, a composite product can be combined and designed with a view to specific load-bearing capacities, while providing a number of advantages in relation to traditional materials, such as resistance to chemicals, as well as electrical and thermal insulating properties.
Composites are widely being accepted in the current times due to their following characteristics-
- Excellent resistance to chemical and corrosion–Composites offer greater resistance to acid, salt, alkali and electrochemical environment
- Greater strength to weight ratio than steel or aluminium
- Lightweight and manageable-Composites have a specific gravity that is one quarter to that of steel and two thirds to that of aluminium
- Non-conductive - outstanding electrical and thermal insulation
- Transparent to radiofrequency transmission
- Excellent creep and fatigue performance
- Exceptional cost performance-
A low installation cost, long-lasting life and minimal maintenance makes it a cost effective solution
