After 7 years designing and making composite products I moved on late last year. I’m now at a company that is producing nanofibre composite reinforcement material. After reading about nanofibre and the effect it has on composites for years and then not finding commercially available supplies. I’m happy to say we have cracked it and can produce in large quantities, at a ever decreasing price.
The product is called Xantu Layr, it is a poly-amide nanofibre sheet which when interleaved with composite will: [ul]
[li]Improve interlaminar shear
[/li][li]Improve compression after impact
[/li][li]Improve resin toughness
[/li][li]Improve flexural strength - http://youtu.be/DE4ARnSne_M Please excuse the music
[/li][li]Reduce crack propagation and delamination
[/li][li]Add almost no extra weight - between 1.5 and 4gsm depending on weight of fibre used
[/li][li]Appears to improve bond strength to foam (we are in the process of confirming this) http://youtu.be/3vyf8UbGUwQ
[/li][li]Is much safer to use compared to nano particles
[/li][li]Can be used in wet laminating, VARTM, RTM and prepreg.
Since it is a sheet, you can use it to spot reinforce problem areas and it won’t clump or move like nano particles can. We have a customer using it to reinforce a problem spot on in a mould that would crack when demoulding, since they incorporated it they haven’t had any cracking.
A infosheet can be found here.
We are happy to sell sample packs of different gsm and lenght all the way up to 100m rolls. If you are intrested and would like more information PM me.
