flexural bending tests for pre-preg honeycomb sandwich panels

#1

[b]Hello,

i need to determine the sandwich panel flexural strength and stiffness following ASTM C393 which is updated to ASTM D 7250.

The face sheet is of carbon fiber(phenolic resin) and core of Aluminium AL5056.the strength values for the Aluminum is quoted in the manufacturer’s literature(coupon test results).

i am looking for guidelines for selection of specimen dimensions and loading configuration and most importantly the guidelines on the test fixture setup with recommended geometries and specifications(material of load application apparatus,load span,recommended geometry and material of reaction supports etc).

thank you,

regards, [/b]

I don’t have the ASTM standard near me, but it should have all the dimension info you need, along with fixture setup inside the standard…

Hello Riff,

i got hold of ASTM D7250 standard.Does it purport to honeycomb sandwich panels too?
