In recent years, various considerable works performed for strengthening of the structural members such as beams,
slabs and columns with the composite material. Large number of strengthening techniques have been carried out in the previous
years but the most popular is external bonding of hybrid composite material laminates. Now- a- days RC beams are wrapping
with Polymers such as Glass Fibres and Carbon Fibres are more popularly used .This paper presents a brief overview of physical
and mechanical properties of Metal Matrix Composites
