Howdy.



WellI am trying to make a rather small part. It is the knuckle cover for a seatbelthinge. 9x7 cm and bout’ 3 cm deep, in the shape of a triangle.



What’sthe correct way to get that mesh and peel ply to go in all the tight areas? Ihave been cutting the peel ply in strips and over lapping it, and the mesh Imake it in to parts, then snip the edges so the flex better..



Thanksfor any help!

If Brute Force Isn''''t working your not using enough...

Hi Dennis,

In our experience elasticated bagging films do slow down infusion mesh noticeably. We've done side by side 'infusion races' between our normal film and our Elastifilm, the normal film probably around twice as fast. The reason is the way that the elasticated bagging films suck down into the shape of the infusion mesh, thus really restricting the flow gaps that the mesh is there to create. It still works but it's quite a bit slower.

It's true that epoxy sticks to the Elastifilm, I take your point about this not being on the product page and I might add something to that affect but Fred's right that the release properties of bagging materials (apart from release films of course) are generally not included as part of a material's specification. If you use a peel-ply then it's a mute point because even if the bag, mesh and peel-ply are all bonded together then you would still be able to remove the peel-ply from the part (although it might be a bit more tricky).

For general infusion, I would recommend our vacuum bagging film film. It's a top-notch film and one you're familiar with the bagging technique you shouldn't have any problems with leaks around the pleats etc.

[UPDATE - I've added this infor to the Elastiflm product page]
