20KN glass fiber tensile strength testing machine 2 tons
Test fixture
1. The width of the fixture should be greater than the width of the specimen
2. The clamping surfaces of the fixture should be flat and parallel to each other, and the force should be evenly applied throughout
the clamping width
of the entire specimen, and the specimen should be prevented from slipping or any damage inside the fixture.
3. The clamping surface of the fixture should be as smooth as possible. If the clamping sample cannot meet the requirements, the
serrated and wavy
fixtures used should use rubber sheets as cushioning materials.
4. When clamping the mesh, it must be in a straight line to ensure uniform stress during stretching.
