Hybor Material-
(OP)
My company has recently wanted to employ HyBor laminate (Boron/Epoxy) in an aircraft application. I have heard that there is significant handling concerns regarding the material. Has anyone used this particular material, and are there any issues that I should be aware of as I implement the material in the design? I calculated the $/weight, and its approximately on the order of $1000/lbf, so it's pretty expensive.
The primary application is in pure bending, and thus the thought was only to use uni-directional plies. The one significant advantage is that the strength of the material is nearly twice of standard gr/epoxy laminate (which is why we are considering it in compression/tension application).

Boron
Effects of Exposure: Boron compounds are very toxic and therefore considered an industrial poison. Boron is one of a group of elements, such as Pb, Mn, As, which effects the central nervous system. Boron poisoning causes depression of the circulation, persistent vomiting and diarrhea, followed by profound shock and coma. The temperature becomes subnormal and a scarlatina form rash may cover the entire body.

You are right, I was thinking of beryllium, but since I found that MSDS, you'll be hard pushed to use it in production. We've had to eliminate lead from our plant.

RE: Hybor Material-
As compositepro says, the fibres are very tough and are just waiting for an unwary hand.
If during your design you can do a layup schedule that will put the boron under a layer of carbon or glass so that it is not abraded later, you should not have a problem.
