ABSTRACT:
A process for producing a composite element comprising a plurality of sheet members 64 rigidly secured to a support 65 with their rear main faces in contact therewith, characterized in that the sheet members, which have a perceptible reflectance, are placed on a jig 61 in one or more predetermined orientations relatively to one another, and a fluid, settable substance is applied to the thus arranged sheet members 64 e.g. by pouring from a ladle 66 and is caused or allowed to set at least partially while the sheet members 64 remain on the jig 61 to form at least part of a substantially rigid support structure 65 for the sheet members 64.
The invention includes a composite element which comprises a plurality of sheet members 64 having a perceptible reflectance, the sheet members 64 being rigidly secured with their rear main faces in contact with a surface of a substantially rigid support structure 65, the sheet members 64 also being arranged in one or more predetermined directions, the composite element comprising one or more members 69 secured to the rear main faces of the sheet members 64 and embedded as by casting in the support 65 to provide a key therefor.
