|The shear test using DIN SPEC 4885 is a picture-frame shear test. Laminates with thermosetting or thermoplastic matrices reinforced with fibres in 0°- or 0°/90°- direction can be tested. The square shaped specimen is built symmetrically and balanced around the midplane. Typically the thickness of the specimen is 2 … 4mm.
It requires expensive test fixtures and significant amounts of test material, as opposed to the established tests. But it provides great advantages:
For the shear test using DIN SPEC 4885 we developed the picture-frame testing system GZ-S80. Hydraulic clampings provide quick and easy change of specimen. The testing routine takes only few minutes, so it can be integrated into industrial environments for shear tests series.
