How do I ensure aluminium honeycomb is bonded to fabric for composite sandwich ?

Group: Awaiting Activation Posts: 6, Visits: 23	Hi If I want to create a decent thickness solid composite sandwich panel to use as a caravan side panel (sort of) and I need to construct the components like the sides, top, floor, front and back I am considering using aluminium or solid core with a combination of CF/Glass and Kevlar for strength and impact combination - possibly with ply on the inside to bolt things to internally. I have a couple of specific questions; 1) I cant find anywhere that explains how to create an Aluminium core composite and how to bond the core to the fabric and if it can be infusion formed. 2) If I am going to construct a big 3D construction, how do I choose the right sandwich components for a good combination of rigidity and flexibility and ease of production - I am thinking about silver glass (or 2x2 CF) on the outside with 2x kevlar layers around aluminium or foam core ? 3) If I find the right combination of sandwich materials and create a side panel and a roof panel how do I join the two - I understand the different techniques but just want to choose the right combination of epoxy, bolts, extrusion etc. - I don't want to just bond the two together and find the roof peels off on the motorway! What particularly concerns me 4) It occurred to me that I could build a box-ally frame and then I would have a solid base, for example to bolt a spare wheel to. Then I thought should I try and build a frame into the composite shell or just both the sell to the frame or is having a frame overkill. Thanks DF Tags Aluminium Honeycomb Bonding Chassis Rigidity

Carbon/Twaron is in stock now, I'll get it added to the website so you can purchase online but in the meantime if you want some and it's not online just give us a call. Price will be the same as 188g carbon/kevlar. I guess I have to do the stress testing as you suggested and I see that you have some trial sample fabric kits but they are a bit small - do you have any random offcuts (or is that where the sample kits come from)? It's not where the samples come from but generally we don't have a lot of offcuts. If you place an order in the future and would like to ask at the time whether we can include any available offcuts of reinforcement then I'm sure we'll try to accommodate.
