Effect of Nanoclay on the Flexural Creep Behavior of …

11 · The effect of nanoclay on the short-term flexural creep behavior of polypropylene/wood flour composites was investigated. The results obtained showed that the flexural strength and modulus increased with contentt of nanoclay up to 3 phc and then decreased. The fractional deflection and relative creep decreased with increasing content of nanoclay.

28 · I have drawn a blue line to roughly illustrate the average tendency. It appears that the flexural strength values are roughly 1.5 times higher than the tensile strength values. There are some exceptions and it would be unwise to simplify the case by making it a rule of thumb, but the tendency is probably worth making a note of.

4 · The flexural strength (transverse strength, modulus of rupture) of a material is measured with a three-point bending test, in which the load is applied in the middle of a simple beam which is supported at each end. Flexural strength of a material is tested to determine both the strength of the material and the amount of the distortion expected.
