A resent developement is to use UV curing. Check out: http://www.compositesworld.com/ct/issues/2005/April/795
Maybe it works for your problem. ONly thing is that you cannot use it for CFRP, since UV rays cannot penetrate them.
Hi,
I have to determine the first eigen frequencies of a wind turbine placed on the sea bed (north sea). Interaction with the sea bed has to be investigated. My first idea is to model the stiffness of the soil with springs. (and leave the mass of the soil out). Does anybody have experience with...
Hi,
For a project i have to analyse the first eigenfrequencies for a windturbine placed on the sea bed. Problem: how do i model the influence the stiffness of the sea bed. My first guess is to model the stiffness with springs. WHat is a good first estimate of the stiffness of the seabed? Where...
Thanks,
PRoblem is that i have to have two guide rails with the same curvature. Guidance should be accurate (around +/-2mm) so the two rolled strips should be of the same curvature.
Btw: how about the transition from the large radius to the small radius? is this possible?
Hi
I need a steel strip (St52) (thickness10mm, height 60mm)to use as a guide rail for a curved door. The strip is 2.5m long, and has two radii. First part radius: 3.5m, 2nd part radius: 0.35m).
I am thinking of making this rail by rolling the strip. What tolerances can be met with the rolling...
I forgot to mention that the primer was green. Because there was green residue on both the aluminum and the CF part (the fracture surface was completely flat, the adherents didn't fail). Hence we concluded that the primer itself had failed.
The joint is a scarf joint, where both the CF and the...
Hi,
We bonded carbon composite (CF-epory) to aluminium with 3M EPX DP490 adhesive (epoxy). A metal primer (epoxy, also from 3M) was used for corrosion protection (galvanic corrosion). On test samples we saw green residue on both the CFRP and the aluminium, indicating that the primer itself had...
