ASTM D 2344 specifies testing method for determining the short-beam strength of high-modulus fiber-reinforced composite materials.

SPECIMEN

Short beam specimen machined from a curved or a flat laminate up to 6mm (0.25 in) thick.

Recommended specimen geometries

Specimen length = thickness x 6

Specimen width, b = thickness x 2.0

APPARATUS

VIDEO:

Example Photo to show jig. 

Sample and set up is not related to the standard

Figure 5 jig is used for curved beams.

Upper punch is a Ø6.

Lower free sliding bases are able to slide freely on rollers when force is applied on it.

The rollers and the base are held by springs allowing the base to slide back in to position (12mm apart).
