I found this while I was surfing for some prepreg
http://www.atlasortho.com/easypreg/index2.htm
has anyone experience this before? the price seen to be extremely high though.
Thermoplastic prepreg is quite different to work with than wet bagging, infusion or thermoset prepreg. As you can see in the video on their website, the fibers do not comform to the mould at all. It is just when a vacuum is applied, that the fibers take shape.
There are certain products that are nice to do with this type of material, but other products are hard to make.
These product do have their purpose.
I do not like, at ALL, the fact that they do not tell you what resin they are using. I would not make anything out of PP if I didn’t have too. Soft, low service temp, etc. Yet they make it look easy, and don’t give any info. Hmmmmmmmmm…
It can be nylon as well. One of my customers uses nylon vacuum bag as the resin. He places a lot of nylon bag between layers of fabric, then presses it down, and into the oven, to melt the nylon (at 250C or so).
Nylon is OK for a lot of parts, like bicycle seats, etc. Also the Aerospace industry is looking into it. (mostly by infusing caprolactam, which cures into nylon)
Also I feel, from the site, that it is mainly targeted at orthopedic stuff. Also then it should be OK, with a bit of flexibility, and Tg is not important (OK, over 100F please…)
am I reading the price list right? $207 for a sqm?
wonder what vac bag. Many are treated so they don’t melt…juuuuuust burn. Prob the cheaper ones aren’t. nonetheless, nylon is ok…but just the fact that the company has NO tech data…eeeeeeehhhhh…
Yes, you do not need an advanced bag for that purpose, if you are melting them anyway. Never heard them complain about pinholes or porosity either…
