Joining sandwich materials

Customer question:

Are there any disadvantages in terms of workload or strength if sandwich materials are processed in butt joints, i.e. if smaller pieces have to be processed due to a lack of availability? Does the sandwich material necessarily have to be scarfed like a wood veneer?

From my practical experience, I can say that stapling them together with superglue or other adhesives is perfectly fine. The support material only takes on the task of creating a light wall thickness with load-bearing outer skins. With very thin outer skins such as Carboweave, it can happen that the joints are slightly marked, especially with very low-resin construction.

Butt to butt should be glued! I consider butt jointing to be very time-consuming, as there must be no cracks in the material thickness. When glued, the stock always has different strength values. This is not noticeable, only visible on very close inspection.
