Material Testing Machines for Marine, Shipbuilding and Offshore Applications
Marine manufacturing brings together structural metals, composite panels, bonded joints and flexible load-bearing materials. DAK testing systems help laboratories examine their strength and deformation, with the specimen, loading arrangement and measurement selected around the engineering question.
Your testing application
Connect the marine material to the right test
Shipbuilding metals and welds
Tensile specimens taken from parent material or across a welded joint address different regions. Bend tests add information about deformation of the selected material or joint. Record specimen orientation and weld position with the result.
Composite laminates
Marine laminates are evaluated through loading modes such as tension, bending and shear. Reinforcement direction and laminate construction belong in the test definition so results can be compared meaningfully across materials.
Sandwich panels and core materials
Core compression, flatwise tension and panel bending investigate different parts of a sandwich construction. Identify whether the test concerns the core, the face-to-core bond or the response of the panel specimen.
Adhesive joints and coatings
Bonded substrates and coated specimens need a loading arrangement that matches the bond being assessed. Joint geometry, substrate preparation and failure location help make a strength result useful for material and process comparisons.
Ropes and rigging specimens
Breaking force and extension describe different aspects of rope behaviour. Steel and fibre ropes also differ in construction, gripping and end preparation. Include the termination and free test length when planning the test.
Coated fabrics and flexible materials
Strength, tear and layer adhesion address different performance questions for coated textiles. Identify the material direction, coating and joint or seam being assessed before selecting the gripping and test method.
Configure the test
Account for construction, preparation and test conditions
Where the force enters the specimen
Metal grips, laminate tabs, sandwich loading blocks and rope terminations create different load paths. Include these interfaces in the specimen drawing so the configuration addresses the intended failure region.
What deformation is measured
Specimen strain, panel deflection and rope extension are not interchangeable. Choose the measuring location, gauge length and movement range around the property you need to report.
Material history and conditioning
Record whether the sample is dry, conditioned or tested after environmental exposure. Also distinguish preparation before a test from controlling the environment during loading when discussing your equipment needs.
DAK testing systems
Choose a platform around your laboratory
A material-testing programme may cover several loading modes without using the same fixture for every specimen. Compare the UTM platform and accessories against your metals, composites, joints or flexible materials.
DAK flagship
Series 7200 Universal Testing Machine
Our flagship universal testing machine brings flexible programming, specimen setup and measurement together for a broad marine-materials laboratory, with tooling selected for the test at hand.
Series 9000 Universal Testing Machine
A universal testing platform for established material and component methods. Compare the published force range, working space and control approach with the requirements of your marine test programme.
Repeated-load evaluation
If the programme includes fatigue, state the load history, cycle requirements and specimen configuration. This keeps a repeated-load study distinct from a one-time strength measurement.
Standards and methods
Find marine-material and joint test methods
Start with a relevant method shortcut or use the complete marine library. Match the reference to the material, specimen construction and required result, rather than treating a sector label as a single test.

Before you specify
Make the equipment enquiry specific to your specimen
Material testing or complete rigging evaluation?
A short rope specimen and a complete mooring or rigging assembly can require very different test lengths and fixtures. Describe the actual assembly and loading plan, not only its nominal breaking load.
Core strength, bond strength or panel behaviour?
A sandwich panel can be examined at several levels. Decide which part of the construction is under investigation before choosing a compression, tensile or bending fixture.
