carbon fiber/glass fiber laminated analysis

[Stefan85]

Good evening to all,

I have not yet found the right way.

I have as a goal to carry out a structural analysis on a laminate obtained by pressing carbon fiber and glass fiber prepeg.

In particular, I should subject the laminate to vibrations present during the launch of a satellite and those resulting from thermal stress.

what tricks and especially what software do you recommend?
also for a simple preliminary qualitative analysis.

Thank you.

Bye.

depends on the context (aerospace, academic, industrial mechanic). in principle I found myself well with the composites with the different variations of nastran (msc, in). competitive (especially for the quality/time ratio) pro mechanica (mixed crystal). I have not experienced ansys and cosmos (solidworks sim), but I assume that at least the first is very close to nastran.

Good morning

Thanks for the answer.

the context is academic, I must "simplely" simulate the behavior of this laminate in carbon fiber/glass and one with only fiberglass.

are there particular complications in using these sw to set the characteristics of the fibers and indicate that these prepregs go to form a single laminate?

Thank you.

Hello stefan85,
If you use laminates, I recommend using hyperworks as you have the ability to model the composite as it is actually produced, i.e. by thinking about the shape of the skins (ply) with their sequence and you don't have to go to split the component to understand what layers it is made. or you can use the ply based approach and not the zone based approach (which is still usable in hyperworks).
with this ply based approach, you also have the advantage that you can graphically see skins as you have and how transition zones are made (in 2d and 3d display) which is an extremely useful thing to understand if you did well.
In this way, you also have the advantage that in post-procession, i.e. when you go to see the results, these you can see them directly for each skin and then understand if there are problems.
in the hyperworks world, there is then a unique solution regarding optimization.
