CATIA Composer with Composite Part Data

Posted by Justin Brash on 05-Apr-2018 12:01:00

In this short video, see how CATIA Composer can import native CATIA V5 Composite parts, and preserve all of the Composite Design and Analysis data for use in creating rich 3D documentation.

A simple example of a CATIA V5 Composite part is used in the video, modelled using the 'Zone Approach' with one main laminate and four thicker, reinforcement laminates. 

Learn how to open and select the CATPart from your file browser and see how it replicates in Composer, with all the geometry included.  You will now have the ability to design and capture multiple scenes (or views) as well as create high quality key-frame based animations.

Composite Zoning Optimisation

Posted by Andy Woodward on 15-Jun-2017 16:58:33

It is for good reasons that designing laminated composite structures is sometimes known as a ‘black art’.  It is not easy to intuit from the topology of and loads applied to a component what a good ply layup should be.  Many companies rely on the wisdom of veteran engineers’ hard won experience, but sometimes it is necessary to take a step back and ask “what else could we try?”.

Often the design of a composite layup starts with the definition of zones within a part.  The layup on each of these zones can then be fettled using FEA to arrive at a stacking sequence which can then be used to define plies. 

But how do you choose the zones? Is it arbitrary based on the topology of the part? Do you just chequer-board your panel into regular squares?  You could use a technique developed with MSC Nastran for one of the F1 companies.
