Roland's homepage

My random knot in the Web

Me at work

It occurred to me that I only rarely have a picture taken with me in it. Usually I’m the one holding the camera. So here are a couple of “action shots”. :-)

R.F. Smith performing a flamability test R.F. Smith during infusion of a first prototype

The first picture is me doing an informal test to see if a material that we made is self-extinguishing according to UL 94 V-0.

The other picture is me watching the vacuum infusion of a new glass fiber part for which I did the initial design and calculations. A stack of layers of glass fibers and filler materials is laid in an aluminum mold, and covered with a translucent foil that is sealed at the mold edges after which a vacuum is applied. Activated polyester resin is then fed through a hose into the glass package and fills the voids between the fibers. When after some time the resin has reacted and hardened, the product is taken out of the mold and processed further.
