MMA Memo #219

Report on Visit to Composite Optics Inc.

John B. Lugten [1]

July 9, 1998

Keywords: antenna design, CFRP

This memo summarizes my recent visit to Composite Optics Inc. to update them on recent MMA antenna designs, and discuss in detail the antenna components which are likely to be of composite construction. I presented my concept for an all CFRP primary mirror support structure using pultruded truss elements joined by laminated plate gussets. COI commented on the strengths and weaknesses of this approach and gave an update on their continuing development of the laminated plate all CFRP structure. COI provided engineering constants for particular CFRP laminates (which are in good agreement with values we have assumed until now) which will give our future modeling work a greater level of accuracy.
