T800H Fabric Properties
T800H Fabric Properties
(OP)
Hi, I doubt at the properties below. Based on Toray website, T800H is fabric but the table below shows the modulus more like unidirectional.
What do you think?

And why the hell can’t you post all of your composite questions in the same forum?
RE: T800H Fabric Properties
T800 is fiber. T800H is dry fabric; T800S is unidirectional tape. So, I expect for the modulus for two directions should be quite close to each other, right?
RE: T800H Fabric Properties
T800 is generic fiber name.
T800H is T800 fiber with H type sizing/surface treatment
T800S is T800 fiber with S type sizing/surface treatment
Or something like that. If you need details, call you Toray sales rep.
RE: T800H Fabric Properties
Both types are carbon tow, not fabric. One type is probably preferred for fabrics use. Fabrics are usually solution impregnated, and highly collimated carbon fibers may not soak-up enough solution to reach target resin content. Twisting and untwisting tow disrupts the collimation and increases the bulk of the fabric, slightly.

I might have confused from the website that T800H common application is weaving by T800H is fabric...
