Hi guys!

2 quick ones:

Q1: Is the adheisive normally used for CF the strongest availiable for that material?
You know when you read about some stealthplane that was glued together? Exactly what kind of glue is that? I don´t mean 
to use it for CF, but that glue must be the best possible for that type of material, so what would be the counterpart for CF?

Q2: If you want to make a superstrong laminate structure, like the one used in high performance sportscars, what recipe would you use?
Without pre-preg that is. What laminates, what core and in what order?

for Q1,  the type of adhesive to use depends on the end application. What you are bonding together, what environment its in, type of stress its under, structural/non-structural parts etc etc etc.    If you look here: EC shop adhesives section you will see there is a number of different adhesives for different purposes.    You need to look for one that best suits your needs and if necessary ask for some advice from the team on here.  Im sure they will be able to advise what adhesives might suit your needs.

for Q2, again it depends on the application.  depending on the application will determine the type of core material used, the number of layers of carbon/laminates etc etc etc  The specification for a structural part of the tub would be totally different to a light body panel for example.

Q1: I already purchased one of each type, I meant in more general terms. Say I want a semi rigid adhesive, is the standard glues we use the strongest?
Also, what is stronger, an adhesive between two cured parts or having one cured part and casting the other part as at wetlay directly on it?
Since it is the joint between two epoxy surfaces we´re looking for, couldn´t you use epoxy as an adhesive?

Q2: For the body 200gr + 3mm soric + 650gr seems to work. I´m thinking of the heavy duty parts, the tub, the front and rear where the suspension and steeringmodules will be bolted to the chassie.

call up a manufacture of adhesives like permabond and have a chat with them about your application they will know exactly what they are talking about and they have a lot of experience. Structural adhesives are a very specific thing there are many different working environments/conditions that certain adhesives are specifically designed to deal with.

Also on a side note that ply layup "200gr + 3mm soric + 650gr"  is unbalanced and so the part could warp when curing.

Paul or Matt from the staff said in a previous post that he would use structural polyurethane between two composites, and epoxy to bond composite to metal or aluminium.

If it can help in any way...
