poymer composites used in automobile industry,marine ,aircraft,medical ... by adding fiber matrix it gives strength to the applications..Common types of engineering materials include metals, polymers, ceramics, and composites. Among these, composite materials are often a better alternative for traditional materials, such as metals, ceramics, and polymers due to their light weight, corrosion resistance, high strength and stiffness, ability to withstand high temperatures, and simple manufacturing process [1][2]. Composite structures are used in a range of different industries from aerospace, marine, aviation, transport, and sports/leisure to civil engineering. For example, advanced composite materials have been used in different structures regarding the above industries, such as rotor blades, aircraft main body, and wing skinsFibrous composite is a type of composite materials that includes fibers integrated with a matrix, owing its remarkable stiffness and strength to the fibers. Fibers can be classified based on their length into long and short fibers. While long fibers are usually produced in straight form or woven form, short fibers, also known as whiskers, possess better strength and stiffness properties. The geometrical properties of a fiber are usually characterised by a high length-to-diameter ratio as well as its near crystal-sized diameter. The effectiveness of a fiber is, however, determined by its strength-to-density and stiffness-to-density ratios. Fibers can effectively improve the fracture resistance of the matrix , and the long-dimension reinforcement made by fibers stalls the growth of the cracks initiating normal to the direction of reinforcement.

7. FIBERGLASS
glass E (electrical):
exploited only by its electrical properties, it is the most cheeped .
Glass R (resistance):
Have greater resistance than E. it is used mainly in the field of aviation, space and weapons.
Glass A (high alkali content):
Mechanically less resistant than before.
Glass C ("chemical"):
are characterized by good chemical resistance. Mechanically they would be among the fibers A and E.
Glass D (dielectric):
thanks to its dielectric properties are used for electronic materials in tele communications, radar and
electromagnetic windows.
Glass B (Boron):
excellent electrical and durability, calcium borosilicate properties is high in alkali.
Glass X:
Based on Li 2 O being transparent to X-rays
