Fatigue tests at a special price

 

 

As a follow-up to the JEC Paris 2019 we offer you a special price for fatigue tests to determine S/N curves. You will receive a discount of 25 percent on the corresponding tests if you order before May 17th 2019. The tests take place in our accredited testing laboratory:

  • Tests under various load conditions, e.g. R = -1 (alternating tensile/compressive load), R = 10 (compressive/compressive load) or R = 0.1 (tensile/tensile load)
  • Testing with calibrated servo-hydraulic universal testing machines (MTS)
  • Execution of quasi-static preliminary tests to determine the strength
  • Sinusoidal load type with peak value control (force or displacement)
  • Test frequency as a function of the load horizon
  • Test specimen production (CNC milling) and measurement with calibrated measuring devices
  • Application of strain gauges for R = 0.1 on request
  • Preparation of detailed test reports including the S/N curve, the straight line according to Basquin and the stress/cycle number curve in a semi-logarithmic diagram.
  • Sending of raw data in CSV format on request

The tests can be implemented promptly. Just contact us, we will be happy to make you a personal offer!


The entire Grasse Zur Composite Testing team congratulates Olympic Bobsleigh Champion Mariama Jamanka (Oberhof) on her double victory in Whistler! One year after her sensational triumph in Pyeongchang, she crowned herself World Champion for the first time. At the title fights in Whistler, Canada, the 28-year-old won the gold medal on Sunday with pusher Annika Drazek.

We are proud to be able to test for the Institute for Research and Development of Sports Equipment (FES), without whom this victory would certainly not have been possible!


This year we are exhibiting for the first time at the most important international trade fair for fibre-reinforced plastics and composites. JEC Paris will take place from 12 to 14 March in Paris. You will find us at the booth of the German Aerospace Center DLR in hall 5 / booth E 67.

A free ticket is available here. You are welcome to forward this newsletter or the link to interested colleagues.

We would like to inform you about current developments of our testing services. Our accreditation according to ISO 17025, which allows us to test for the aerospace industry, is particularly important. In addition, our online process control GZ US-Plus, which has been used successfully for more than twenty years, will be in the focus of the trade fair. The US-Plus technology is the only process control on the market that can measure contactlessly.

We look forward to your visit!


Picture Frame Shear Test According To
DIN SPEC 4885 / DIN EN ISO 20337

 

The picture frame shear test according to DIN SPEC 4885 / DIN EN ISO 20337 is the reference test method for determining shear properties for fibre-reinforced plastics (CFRP and GFRP). The test method represents a significantly improved test method compared to all other shear test methods, as higher material characteristics are achieved with simultaneously lower standard deviations. In our test laboratory accredited according to ISO 17025, we are happy to carry out contract testing according to all important standards for fibre-reinforced plastics.

The Grasse Zur Composite Testing team congratulates Theo Reinhardt and Roger Kluge on winning the 108th Berlin Six-Day Race. This victory would not have been possible without their FES track bike.

We are proud to test for the Institute for Research and Development of Sports Equipment (FES)!


Do you or your colleagues want to learn more about composites? Would you like to refresh your knowledge around the topic “testing of fiber-reinforced plastics”? You would like to exchange information with other users in the field of material testing? Then you should not miss the next professional seminars at Grasse Zur Composite Testing!

The seminars are aimed both at beginners and experienced material engineers:

Overview of Test Standards – Composites Testing! [PDF] on 24 + 25 January in Berlin

Proper Curing of Resin-Hardener-Systems – Part I [PDF] on 21 + 22 February in Berlin (focus on DSC)

Service Strength of Composites [PDF] on 14 + 15 March in Berlin

Simulation of Carbon Components [PDF] on 28 + 29 March in Berlin (in cooperation with ar engineers)

Proper Curing of Resin-Hardener-Systems – Part II [PDF] on 23 + 24 May in Berlin (focus on DMA, rheology, curing kinetics, process control)

The seminars offer the time and opportunity to make contacts, introduce your everyday challenges and questions and to discuss them in the spirit of an exchange of experience. The discussions can be continued with the dinner together in a pleasant atmosphere.

If several employees come from one company, we can give you a small discount. We also offer a discount for student and academic staff. Just contact us.

Afterwards, it is a good idea to extend your stay with an interesting weekend in the capital Berlin.

Further information and registration options are available here!


ISO 17025

 

We are delighted to inform you that our test laboratory has been accredited to DIN EN ISO / IEC 17025: 2005 since 2 November 2018. After two years of intensive preliminary work, we were able to convince the examiners in April of this year of our competence to carry out mechanical-technological and physical tests on plastics as well as fiber composite materials and products made from them. The accreditation has taken us a big step forward in terms of technology and organization, and we can now test for aerospace, medical technology and automotive with significantly less effort.

If necessary, we can perform short-term material audits and analyses for you. By the end of the year, we still have spare capacity so we can help you complete your projects by the end of the year.

Talk to us at any time without obligation. We will advise you!
