Has any one worked with Zylon?
(OP)
Just trying to get some more information regarding Zylon or zylon/carbon hybrid. I am looking to see if this fabric is worth working with and what the drapability, what resin type works best for it. I have been reading that this has much better abrashion resistance and heat resistance than Kevlar. Any Information would be appreciated, application wise i am looking to use it for a rear diffuser with exhaust ports on a vehicle. The problem i have been running into is the egt's and finding a soulution for a resin that doesnt break down over 200deg even after post cure.

Thank you for being the one and only person from multiple forums to give me an answer at all, never mind the knowledge you have on this product. I will be looking into the Bismaleimide, for the hi temp areas. Does that product require a post cure cycle or does it cure with Hi temp. properties? I was thinking that the zylon properties would be good for a specific area were the exhaust pipe would meet with the diffuser. The exhaust would need some sort of flex area so that its not attached at a ridged point do to normal movement in startup and different driving conditions. Would the V.A.R.T.M achieve the same result.

For the highest temp commercially available plastics suitable for matrixes check out polyimides, such as Cytec's Avimid N, which has a claimed dry Tg of 410°C (375°C wet). However, stay away from ones such as PMR-15 which have MDA in them, as they're bad for you. PBI, a thermoplastic (polybenzimidazole), can go even higher, but I don't know of it being available with continuous fibers. BMIs can be happily processed at 100 psi and maybe 200°C with a free-standing post-cure of maybe 230°C. PIs though may need 200 psi and 320°C. As Moudoc observes, curing BMIs out of autoclave (OoA) is not advisable. ACG do a BMI which they claim can be cured OoA, but they do warn that it will be much more porous.
Re Zylon (aka PBO), we've played with it a bit. It looks useful for armor, but it should be fairly useless for a weight-efficient structure, as laminates of it have very low compression strength (much like Kevlar). Unless it's a tension structure such as a sail, structure-wise you're better off for high temperature with glass (maybe carbon if temperature is <=300°C) in PI, or maybe alumina fiber such as 3M's Nextel, though that may be overkill. If you're tension-only the data from Teijin show reasonable retention of Zylon tensile properties at 400°C. Zylon also degrades quite quickly in sunlight (see North Sails's notes for rigging made of it).

PEEK requires processing at 700F and does not blend with other resins well. Raptor Resins supplies BMI resins that can be used for vartm and other out-of-autoclave process, and can be cured at 350F.

Did you looked at the Cyanate ester resin?
It is thermosets and high temp (don't know about abrasion or impact resistance. Maybe it is complying to your requirements.
TenCate is supplying this resin, they are supplying resin for vartm/infusion and prepreg.
