i request u to give me seminar report of thermal expansion

the definition of

Fibre/matrix adhesion, most probably to check the overall mechanical behavior of fiber-reinforced composite materials. Interfacial reactions can lead to different morphological modifications in the polymer matrix microstructure in the immediate vicinity of the surface of the fiber. Interaction between fiber and polymer matrix during thermal processing and heat stroke are important phenomena.

Thermal stresses in reinforced epoxy composites under thermal shock cycle (negative to positive temperature effect) for various periods, as well as by reducing the thermal cycles (positive and negative temperature impact) percussion. the concentration of thermal stress often leads to weak fiber/matrix interface. Destruction effect was observed in both modes for short drum loops and then, improving shear strength was measured. The effects have been shown to include two different speeds during testing shift short beam.


Differential thermal expansion cause thermal shock in composite materials. Thermal expansion emigrants between fiber and matrix may contribute to stress on the border [1-5]. Very high thermal expansion mismatch can lead to the violation on fiber/matrix interface and/or possible matrix cracks due to thermal stress [6-8]. fiber-optic interface-the matrix is likely to affect the overall mechanical behavior of fiber-reinforced composite materials.

Performance of reinforced composite is often controlled by the adhesion of chemistry on the border of the fiber/matrix. Thermal coefficients of the decomposition of the polymer significantly higher compared with metals or ceramics. That is why the failure of bond between fiber and resin comes under the influence of the temperature gradient. General fittings for glass fiber polymer matrix. One of the disadvantages of fiberglass bad adhesion to resin matrix.

Short shear beam (SBS) test results may reflect the tendency of adhesion Where only the bonding of the variable [9]. a large number of methods for measuring surface adhesion were registered in reinforced polymer composites [10-16]. There is a need for evaluation of mechanical properties of the composite Is probably under the influence of heat shock.

Thermal stresses due to temperature gradient should be given special attention in many application areas. a better understanding of these properties and characteristics of Interfacial adhesion can assist in evaluating the mechanical behavior of fiber-reinforced composite materials.
