Group: Forum Members Posts: 2, Visits: 8	Hello everybody I want to define mechanical properties for Chopped Strand Mat (CSM) composite material, But I have a problem with the shear test; CSM has random- discontinuous fibers and I don't know how to cut the specimen in _+45 for shear test. Is it similar to tensile specimens? Thanks in advanced
