a laminar panel assembly which is particularly useful in space vehicles for contact with solar cells includes a first and a second cover layer , a supporting core structure interposed between the cover layers and at least one force infeed element disposed within the core structure between the cover layers . the force infeed element includes at least one solid central piece for punctiform load infeed , and shear webs extending from the central piece radially outwardly in a branched formation such that the number of shear webs increases with increasing radial distance from the central piece .
