Abstract
A pre-stressed curved plate comprising a curved plate having at least one concave surface, the curved plate being enveloped and adhesively bonded with tensioned reinforcing fibers, whereby the reinforcing fibers are first wound around the plate under tension being spaced apart from the concave surface and subsequently subjected to pressure to stretch and bond the reinforcing fibers to the surfaces of the plate, where upon bonding, the tensile strain of the fiber introduces stress in the plate.
Claims6
A method of preparing a pre-stressed curved plate having at least one concave surface, comprising:
- winding tensioned reinforcing fibers around a curved ceramic plate whereby a space is left between the at least one concave surface of the ceramic plate and the wound reinforcing fibers;
- and
- applying external pressure to the tensioned fibers to stretch the fibers until they contact and bond to the at least one concave surface, thereby providing a compression stress on the curved plate.
