Theory:

ASTM C1341 covers a flexural test for specific types of ceramic composites. The sampe is bent to about 5% strain and the load is taken. There are three versions of this test. The first is a 3 poinit bend test using center loading. The other two tests use a 4 point bend fixture and use a top span of either 1/2 or 1/3 Lo. 

 

Geometry:

Rectangular plates are cut according to the measurements. Length, thickness, and width must all be measured and recorded for each sample.

 

Solution:

Universal Grip recommends using a bend fixture with articulating supports. Ceramic Composites can be brittle and therefore supports with a slight amount of pivot should be used. 

 

Analysis:

There are several measurement and calculations which can be taken including:

 

- Modulus of Elasticity (MOE) 

- Modulus of Rupture (MOR)  also known as flexural strength
