We often think of composites as being leading edge materials despite the fact they have been widely researched for over 30 years. The material properties they exhibit and the potential benefits they offer in light weight applications has long been understood. However we also know that composite materials can present real challenges when it comes to materials testing. Whilst standards have begun to emerge around the static testing of composite materials, this is not the case in understanding the accumulation of damage and the fatigue life of composite coupons and simple components. Whilst these mechanics are well understood in the world of metals there is still little standardization in the field of composites fatigue.
If you are struggling with the demands of composites testing on your existing machine or perhaps you are considering a new machine, please have a look below at some of the great equipment and upgrades Instron offers to support the fatigue testing of composites.
