Description
The Composites Materials Handbook, CMH-17 contains over 1,000 records of test data for polymer matrix, metal matrix, and ceramic matrix composites. It has been developed over many years by a US-based consortium of leading engineering organizations—originally known as the MIL-Handbook-17 project, and now embodied in the CMH-17 organization.
Using the handbooks in paper or PDF form is useful. But it is time-consuming, does not provide individual property values in a structured form that enables easy search and comparison between materials, and does not automate the output of numbers into simulation programs. Such access can also be highly costly or inconvenient for multiple users spread across an organization.
Viewing CMH-17 data for a Glass Fiber Composite in the GRANTA MI web browser interface. Users can browse the data using the tree view (left) or use the GRANTA MI search and query capabilities. The system stores and dispays text, numerical, and graph data—the user can click on the graph to export the underlying data to Excel.
In Granta's software, these deficiencies are overcome. The data is delivered in a searchable database form. You spend less time looking for data. You can directly compare performance of different materials for a given application. You can make much more valuable comparisons, because Granta's software allows you to integrate CMH-17 with other data sources, such as MMPDS, and then to perform analyses across these sources. You can output data to simulation programs at a touch of a button and distribute the handbook data to the desktop of every engineers who need them.
GRANTA MI is an extremely cost-effective method for such multi-user access to the data. Accessing these references via Granta is also the easiest way to ensure that you stay up-to-date—you receive updates every time we receive new source data from the CMH-17 organization.
Support for education
The MMPDS and CMH-17 data can also be accessed via CES EduPack for educational purposes. More »
