Cut and lay carbon fabric

Just give it a go man, you'll quickly learn what the material can and can't do. Start with the first layer and take your time, if you mess it up visually then just use that layer as one of the backin...

Thank you! I was thinking of making a shape of the internal of the mold with paper and then cut the fabric to shape a little oversized and trim in the mold... good idea or bad idea?

Good idea if it works, bad idea if it doesn't haha. Just give things a try man. I suspect it will be difficult to do like that though, it is a complex shape and the dry fabric is going to move around...

... going to send the mold to Australia soon! 😅😄

So I did it and I am not dissatisfied with the result. I have given a try to the MTI hose and very happy with it, but the resin inlet spiral left a bad print on the part: seems like the carbon under....

Make sure you have enough bag above the spiral hose, then once the infusion is finished you pull the hose up into the fold of the vacuum bag. Either that or infuse from side to side if the geometry.....

Thank you! I will try the fold suggestion as mti videos suggest to place the mti hose all around the part (see the white line in my pic) and place the resin inlet in the middle.

It's much better and much easier to just keep all the hoses off the part. Infusing from the centre is a good idea for larger parts, but for small parts it is really unnecessary and can cause you...

While i agree with you and would do the same, for a beginner it would be safer with the inlet in the centre. With a little bit of bridging the racetracking on such a geometry can ruin your part when....

It's nearly 1.5 meters x 0.80.

Run the feed spiral up one side and the mti up the other.

Hanaldo - 4 Years Ago

Thank you. I did like you suggest with the other infusions but this one has 600 € of carbon in it and I am very worried of a mistake leading to a bad part, so I would prefer to waste some MTI but be....

For large infusions, I take a strip of flow mesh an stitch it to an omega like shape around the spiral feed tube. With that technique the spiral tube can be set off from the part, and leaves no trace...

Thank you for the hint! For the DD compound product, you mean Blade runner ?
