Material Testing for Plastics and
Composite Materials

Lightweight construction and material testing are the insignia of the IMA Dresden – and our company
has been involved with plastics and composite materials since 1961.

Beneficial material properties, versatile areas of use and flexible dimensions gave the plastic and composite market a renewed boost. Today, wind energy, automotive and aerospace industries, along with the rail vehicle industry, are the continuous driving forces for advancing innovation with their demands.

IMA Dresden is an international testing and development centre for inspecting materials and will accompany and support you from the basic material onto production technology and up to, and including, the approval of the finished product. This service comprises not only static, cyclic and dynamic tests but also static long-term tests. The standardised and compliant material samples will be manufactured in-house with wide range of various manufacturing technologies. Furthermore, IMA Dresden has comprehensive experience in the fields of adhesive technology, laminate calculation as well as approval for materials.

We work according to German and international standards and guidelines (DIN, ASTM, ISO, etc.), or in accordance with factory settings. All relevant test laboratories are accredited according to DIN EN ISO/IEC 17025 and moreover are accredited for the business fields of “Material Testing of Metallic Materials” and “Material Testing of non-metallic materials according to SAE Aerospace Standard AS7003 by NADCAP” (National Aerospace and Defence Contractors Accreditation Programme).

Our portfolio

Starting Point for Non-metallic Materials and Connections

We assume the comprehensive determination for mechanical, thermal and chemical characteristics for you as well as determining the loading capacity of plastics, fibre-reinforced plastics, adhesive connections and/or joints hybrid material combinations.

Depending on the requirement, these tests can be executed at low and high temperatures as well as under media influence. We have extensive standard testing technology resources and experience in the design, construction and operation of special test benches for material and component testing processes.

We have also specialized in the comprehensive test topic of thermoplastic composite pipes. The qualification of the “thermoplastic composite pipes” ensures performance, reliability and safety during their service life using the DNVGL-ST-F119 (DNVGL-RP-F119).

Please feel free to contact us when you require a special solution for your testing requirements.

Material creep tests

Components made of fibre-reinforced plastic should be designed to ensure long-term exposure. Material information regarding the behaviour of the component under long-term effects during static loading is therefore required. We implement these long-term tests under different loads as dependent on the temperature and media exposure.
