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.

A pre-stressed curved plate comprising a curved ceramic plate having at least one concave surface, said curved ceramic plate being enveloped and adhesively bonded with tensioned reinforcing fibers, wherein the reinforcing fibers are first wound around the ceramic plate under tension and being spaced apart from the concave surface and subsequently subjected to pressure to stretch and bond the reinforcing fibers to the surfaces of the ceramic plate, where upon bonding, the tensile strain of the fibers introduces stress in the ceramic plate.

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 concave surface of the ceramic plate and the wound reinforcing fibers;
- applying external pressure to the tensioned fibers to stretch the fibers until they contact and bond to the concave surface, and
- cooling the plate and removing the external pressure after bonding.
