Flexural Testing Services for Polymers, Composites, and Plastics

FLEXURAL TESTING MEASURES BEND PROPERTIES OF NONMETALLIC MATERIALS

IMR's Flexural Testing Lab performs bend testing, sometimes called flexure testing, to measure the behavior of materials subjected to simple beam loading. It is commonly performed on materials such as polymers, and composites.
IMR has a variety of 3 point and 4 point bend fixtures, allowing for specimens of all sizes.  The three-point bending flexural test provides values for the modulus of elasticity, and the flexural stress–strain response of the material. As the specimen bends or flexes, it is subjected to a complex combination of forces including tension, compression, and shear. Bend testing is commonly used to evaluate the reaction of materials to realistic loading situations. Flexural test data is critical when a material is to be used as a support structure.
