Influence of Heat and Loading
Time on the Mechanical Properties of Calamus merrillii Becc.
Summary
The influence of heat and loading time on the mechanical properties of Calamus merrillii Becc. was
evaluated by measurement of dynamic Young's modulus and creep compliance at different temperature
settings. Young's modulus decreased steadily as temperature was elevated. Creep compliance,
on the other hand, increased steadily with loading time, similar to wood. Compliance rates were more
or less the same at all temperature settings except for one particular temperature which deviated extremely
from the rest. This temperature indirectly represents the softening temperature. Reduction
in strength caused by heat was highly influenced by the cellular composition of the stem as well as the
sensitivity of its basic chemical constituents, e.g., hemicellulose content, to heat. Knowing this basic
behavior of rattan stems will enable manufacturers to design rattan products more efficiently.
