Flexure testing of Composites
Stress-strain curves achieved from flexure test for four volume fractions are shown in
Figure 16. It is observed from the Figure that the values of flexural strength, modulus,
and strain increase with the increase of fiber loading, as shown in Figure 17 by a com-
parison. Longitudinal strength depends upon the fiber strength and interfacial bonding
between fiber and matrix. On the other hand, transverse strength depends upon only
the fiber-matrix interfacial strength.

impact testing of Composites
It is apparent from the test result presented in Figure 18 that the impact strength in-
creases with the fiber loading. The impact strength is significantly more than that of
PP polymer.
