ASTM D5379 V-Notched Beam Testing (losipescu) of CFRP
The V-notched beam testing method (Iosipescu method, ASTM D5379) is used widely in the field of composite materials for testing in-plane shear. This test method applies an asymmetrical four-point compression load to a sample with V-notches, which enables the application of only shear stress on the evaluation area.
This method can be used with various CFRP laminate materials, including unidirectional materials, orthogonally laminated materials, and materials with discontinuous fibers.
ASTM D6484 Open-Hole Compression (OHC) Testing of CFRP
CFRPs have excellent characteristics in terms of specific strength and high rigidity, but they also lose a substantial amount of their strength when a cutout is made. In order to assess the use of composite materials for aircraft, tests must be performed with samples that have a circular hole cut through the center. ASTM D6468 is an open-Hole compression (OHC) testing method that uses a sample with a 6-mm (0.25-inch) diameter circular hole cut in its center.
ASTM D6468 has two loading methods: method A and method B. This video shows method B, in which the sample is compressed via compression plates located on the ends of the sample and jig.
ASTM D6641 Combined Loading Compression (CLC) Testing of CFRP
Compressive strength is an extremely important property of composite materials for product design. A common compression test method is the combined loading compression (CLC) method (ASTM D6641).
The CLC method can be performed with a simple jig construction, using a long and narrow sample without tabs. It enables evaluating strength and measuring modulus of elasticity simultaneously.
