Safety Data Sheets


Composite Polymers Mechanical Testing

Mechanical testing provides test data to characterize the mechanical integrity of molded resin castings, composites, laminates and sections of molded parts. The data is used to qualify materials for customer specifications, to help design materials for optimum end-use performance or to evaluate the effects of exposure environments on mechanical integrity. The material strength can be evaluated in a variety of deformations:

  • Tensile testing – measures the stiffness and strength of a material as it is being pulled apart in tension.
  • Flex testing – measures the stiffness and strength of a material as it is being deformed in three-point flexural bending.
  • Fatigue testing – applies to a cyclical load or strain to the sample and determines the resiliency or durability of the material by measuring the number of cycles to failure.
