Standard Test Method for Determining Flexural Modulus of Full Section Pultruded Fiber Reinforced Polymer (FRP) Composite Members with Doubly Symmetric Cross Sections under Bending

Significance and Use

5.1 Determination of flexural modulus by this test method is especially useful for quality control and specification purposes.

5.2 Experimental values for flexural modulus will vary with specimen depth, span length, loading rate, ambient test temperature, and other atmospheric conditions.

5.3 Before proceeding with this test method, reference should be made to the specification of the material being tested, including constituent materials of the specimen. Any test specimen preparation, environmental or loading conditioning, dimensions, or testing parameters covered in the material specification, or both, shall take precedence over those mentioned in this test method. If there are no material specifications, then these default conditions apply. Table 1 in Classification D4000 lists the ASTM materials standards that currently exist.

Scope

1.1 This test method covers the determination of Flexural Modulus of pultruded open and closed fiber reinforced polymer (FRP) composites of doubly symmetrical cross sections about their geometric centroid subjected to flexure and shear. This test method utilizes a three-point loading system applied to a simply supported beam.

1.2 The values stated in SI units are to be regarded as the standard. The values provided in parentheses are for information only.

1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
