Lars,
That was what I was wondering about, so the strength isn’t there as opposed to
using Carbon fiber reinforced polymer, correct?
You would have to weigh strength versus costs then.

Subject: [AR] Re: Carbon Fiber Injection Molded parts
It's a good thing. But as I understand it is limited to omnidirectional short
fibers?
They can be useful, and as launch costs come down it will make sense to use
techniques like this but it isn't going to eliminate directional CFRP in the
big important structures or be used to make COPV's in one shot. It might be a
neat way to make a COPV liner, however.
Lars
Thanks,

Greetings and Salutations:
Interesting article I found. BMW has figured out how to use injection molding
to make a motorcycle Carbon Fiber swingarm, allowing it to be made in minutes
rather than hours. I think that this has huge ramifications in Aerospace:

They could mold out large chunks of structure with high strength from what the
article implies. Of course they will have to prove out the strength of the
material.
