Anyone else worked with a prepreg like this before?

[@mrp19285]

I miss working with prepreg. Oddly enough I also liked bagging. When I did it we would bag it then put it in a oven.

[@jacknoname9726]

Bagging doesn't suck until the bag leaks and the leak is nowhere to be seen or heard.

Had a small composite biz/brother in mid 70s. Years later, while being an aerospace contractor, I worked in the composite lab at BF Goodrich aerospace in Everett & got to do all the cool stuff with composites. Prepreg, vacuum bags, heat blankets, computer controlled ramp up & down temp. Came real easy. Really cool stuff!

Just a note, on iOS the top and bottom text was partially obscured by the KZbin UI putting text there

[@howtimflies204]

Prepared is awesome…provided you have the oven. I love it. You guys are doing awesome.

[@mylifeisdope916]

We used out of date stuff for non critical parts. I remember it being a lot more brittle than the stuff that wasn't stored at room temp.

Only every single day. I love it!

Out-of-autoclave prepreg is becoming increasingly more common and better... still not quite up to the quality and mechanical properties of an autoclave but significantly cheaper to manufacture.

[@6stringer301]

look like a good result! I've been lurking around watching the progress of the plane build. The NEXX prepreg looks a lot like the Easy Composites XC110. How does the resin look if there's a bridge in the end product?

[@kerrynicole6595]

If this wasn't used as a mold and was skinned on a product would the nonstick side still have a close finished when heat cured?

[@Kawitamamayi]

How much lighter will turbostratic grapheme (0.06% by weight) mixed resin carbon fiber be? Preliminary estimates are the resin will be 7-10 stronger.

[@jakubzabocki6182]

I love how easy it is to use them but they need good equipment

[@DarkAeroInc]

The big thing here with this prepreg is that you'll want a high temperature mold. This prepreg does not require an expensive autoclave to get good results. All the parts we've made using it has been with aluminum molds, vacuum bag, and a cure oven.

[@KorbinX]

I've used it, albeit very infrequently. I can tell you we stored the racks in a cooler just in case the shop was too hot. Appreciate the videos ^-^

[@DarkAeroInc]

Thanks for checking out our videos! This prepreg is manufactured by NEXX Technologies. The first cure hold point for this prepreg is around 230 F so you don't need to worry about your shop being too hot if you're storing it on the rack.

[@KorbinX]

@DarkAero, Inc oh very neat! Thank you for sharing. The portion we used was 2x2 inches, so much smaller than yours. Very interesting technology and looks far more advanced than the basic we used hah. Hope you and yours are well and, as always, appreciate the videos. Can't wait to see what further progress you make :)

[@tomcoryell]

Cost?

[@Tyler.i.81]

That's cool

[@kyrillkryvenko752]

It that NEXX Prepreg?

[@Kicker700]

Who makes it and where can you buy it?

[@kizzjd9578]

Depends where you are located

[@Kicker700]

USA, Texas

[@DarkAeroInc]

It's made by NEXX Technologies.

[@matthewkenchapman]

What brand is it?

[@DarkAeroInc]

NEXX Technologies

[@kirthianand]

I make prepreg

[@GOAFPilotChannel]

Why use breather with prepreg? Shouldn't it come with the exact right amount of resin?

[@reeceengineering3560]

Because the cure cycle can release gasses that you dont want trapped in the bag

[@SameAsAnyOtherStranger]

How does it take to vacuum forming?

[@DarkAeroInc]

This prepreg requires a vacuum bag and cure oven to get proper flow of the resin and mechanical properties. It does not require an autoclave.

[@jackwake9410]

what pre preg is this

[@DarkAeroInc]

Nexx Technologies supplies it.

[@bayanicustodio3998]

Yes… kinda expensive but it’s all over the biggie airplanes.

[@thegoldenatlas753]

Main reason is prepreg is perfectly made, you dont gotta worry if the resin mix is off or not fully distributed.

[@muskepticsometimes9133]

What's the diff between oven n autoclave ?

[@6stringer301]

Oven = heat only. Autoclave = Heat + Pressure

[@muskepticsometimes9133]

@@6stringer301 thanks

[@tcoles2397]

Used pre preg at Qantas' great product and consistent quality. To be used in aviation the product has a shelf life and must be stored correctly. The pre preg is usable in other non certified applications after expiry. Hope this helps.

[@MadMatty72]

And the humidity was?

[@DarkAeroInc]

We perform our composites manufacturing below 60% relative humidity.

[@kizzjd9578]

Meh, all my prepreg comes from overseas at room temp and works just fine.

[@nathanchalecki4842]

What's the brand and where do you buy from? I have never had the guts to try pre-preg because it seemed like bloody hard work getting it from overseas due to the storage thing

[@kizzjd9578]

@@nathanchalecki4842 i get it off aliexpress in small rolls as im only making small size parts. Just make sure you get the toray t300 or better carbon (t700) and also 42% resin.
