Impact Resistance - Fiber Cement Materials
We were recently asked by a manufacturer of fiber cement building products to recommend an impact system that would allow them to test their products for impact resistance – specifically as related to the installation process. Fiber cement products offer an alternative to owners looking to refurbish the exterior of their homes. A composite material made of sand, cement and cellulose fibers it is fire, rot and insect (termite) resistant. Considered green and sustainable in appearance it can imitate clapboards or shingles; in sheet form it can be used as cladding & as a soffit/eave lining. Besides exterior siding fiber cement can be used to substitute timber fascias.
Either the CEAST Model 9340 or the CEAST Model 9350 Impact Test Machines is capable of performing the tests. A 3 point bend fixture to support the specimens was chosen by the customer. By using tup inserts of different shapes and sizes impacts of various types can be performed. Adding in an instrumented tup, CEAST VisualIMPACT software, DAS 64 Data Acquisition and Analysis System, allows the customer to gather information such as energy absorbed, and incipient damage point from each of the tests performed.
The CEAST 9340 or the 9350 are well suited for helping customers determine the performance characteristics of their materials when subjected to an impact event. The information gathered by doing instrumented impact testing can be used to provide the customer with a data baseline whereby they can determine how changes made in the mix of materials will perform in real life situations. A broader range of testing could be accomplished with the use of an environmental chamber to study impact characteristics at different temperatures as well as using different fixtures and inserts to simulate other impact events.
The new CEAST DAS 64K is a state-of-the-art Data Acquisition System designed for impact testing instruments. Compatible with the full range of CEAST impact testing systems, including pendulum type machines (CEAST 9000 Series) and drop towers (CEAST 9300 Series), it’s the key for instrumented impact testing. The DAS 64K also enables the data collection from instrumented tups or hammers on older models and non-CEAST impact machines.
