Material tests form an essential part of a quality control program and are essential for validation of material and/or structural models. ALE is specialized in tests on fibre reinforced plastics, but can also offer tests on other materials.
Testing of bulk materials or the laminates you produce can provide the information required to consistently produce high quality products. Improved customer confidence and efficient troubleshooting can be further benefits of implementing a well-structured quality control system.
ALE is one of the few companies in the Netherlands that has experience in testing composite materials. We can help you with:
- Implementing your own quality control system (if you don’t already have one)
- Development of detailed material models
- Development of detailed validated (Finite Element) models of the complete test set-up
Some of your clients may require approval by a classification society such as ABS, DNV or Lloyds Register. The society will normally require materials testing to be carried out on a calibrated testing facility. We have experience in dealing with these societies.
ALE can prepare test specimens from test panels or material samples that you provide. Alternatively we can provide advice to those who wish to prepare their own samples.
ALE offers a broad range of tests for fibre reinforced plastics. A number of these tests are carried out in-house and others are done at facilities of partners such as Delft University of Technology.
A selection of the tests which we can offer:
On request, any test can be executed according to customer requirements. For information regarding these, or other tests, please contact us directly.
ALE will deliver a comprehensive report that conforms to the applicable test standard with each series of tests. This implies that not only the test results are provided but most important: the interpretation.
The report typically includes a detailed description of the test procedure, graphic and numerical results, calculations of material properties and a discussion of the failure modes with accompanying photographs.
ALE is unique in its pressure vessel testing facilities due to our revolutionary LoW8 technology. We are equipped to perform almost all necessary certification tests according to the composite pressure vessel regulations R67-01 (automotive use), EN14427 (domestic use), and EN12245 (other applications). More information about ALE’s patented Dry Filament Winding can be found at low8.com. This site is dedicated to all of our pressure vessel activities.
Pressure Vessel Testing
ALE has developed the revolutionary LoW8 cylinder for storage of LPG and other gases. For this Type IV composite cylinder 3 standards are applicable:
- EN 14427: LPG equipment and accessories – Transportable refillable fully wrapped composite cylinders for LPG – Design and construction
- EN 12245: Transportable gas cylinders – Fully wrapped composite cylinders
- ISO 11119-3: Gas cylinders of composite construction – Specification and test methods Part 3: Fully wrapped fibre reinforced composite gas cylinders with non-load-sharing metallic or non-metallic liners
A Type Approval has been obtained for the LoW8 cylinder for EN 14427 (see low8.com).
What can ALE offer?
ALE has the knowledge, expertise and test facilities for carrying out tests on cylinders according to the standards EN 14427, EN12245 and ISO11119-3. We do not use the facilities exclusively for our own cylinder. Amongst others we can offer you the following tests:
- Burst test
- Cyclic test
- (Hydraulic) proof test
- Artificial ageing test
- Drop test
- Permeability test
- Material testing
- Flawed cylinder test
- High velocity impact test
