Aging of Thermoplastics
Most of the currently used thermoplastics take years to age to a degree
where an undesirable amount of material property degradation occurs.
To reduce the time and cost of experimental tests, accelerated material
aging tests are often performed. This paper examines the mechanical
response of two novel thermoplastics subjected to accelerated aging conditions.
Tensile, hardness and impact tests were conducted to determine the effect
of treatment period on mechanical properties. A mathematical model
is of introduced to describe the stress-strain data as a function of accelerated
