Hassan Building and Cons. A simple tensile test is the most popular method of characterising the mechanical properties of a polymer. Decreases in Young's modulus and strength of polymer matrix are experienced while ultimate strain and energy absorption properties exhibit increases (Table 1). Surprisingly, the tensile strength values showed almost no effect due to the substitution of N375/N339 and N550/N660 carbon black in all the formulations. test, there is reorganization in the molecular structures which results in changes in morphology. In the present work, mechanical, thermal and water absorption properties of hybrid sisal/jute fiber reinforced polymer composite have been investigated. 2 C4 54 102. Mechanical properties of solid polymers have been discussed in terms of two approaches: (a) microscopic description of the particular facet of polymer behavior and (b) molecular description using chemical composition and physical structures.

Polyethylene is of low strength, hardness and rigidity, but has a high ductility and impact strength as well as low friction. Polymers have very good mechanical properties; however their properties are not as high as metals. MECHANICAL PROPERTIES AND PERFORMANCE OF MATERIALS Samples of engineering materials are subjected to a wide variety of mechanical tests to measure their strength, elastic constants, and other material properties as well as their performance under a variety of actual use conditions and environments. 1 Bulk Modulus of Polyolefins 10 1.
