Long Fiber reinforced materials
Long Fiber reinforced materials
(OP)
I curently have an ABS that is not performing well strength wise, and I am considering going to either a long fiber abs or even a long fiber polyester. The original material I used in this aplication was 33%GFN, and the warpage of this curved plastic part was unbearable.
I was told that the long fiber materials will not warp and shrinkage rates are very low.
Any thoughts?
Thanks

RE: Long Fiber reinforced materials
Shrinkage will also occur in 2 axis but at different %.
It all depends on your product / process and design
RE: Long Fiber reinforced materials
Shrinkage is primarily a function of process temperatures and fiber volume fraction, there is nothing inherently better about LFTP.
LFTP can have much higher strengths.
How large is your part? How much strength is needed?

We produce polymers that will be able to help.

Check the overall performance of 33% GF nylon vs long strand ABS (not exactly the most common plastic in use these days). You need to know the end use conditions the part will be exposed to. The ABS should warp less, but with the addition of the long fibers its anyone's guess how much it will warp. It depends an the part geometry, wall thickness, gating and molding.
