a process for producing airfoil components containing ceramic - based materials and having a tip cap . the process entails forming an airfoil portion of the component from an airfoil portion material that contains a precursor of a ceramic - based material . the airfoil portion material defines concave and convex walls of the airfoil portion , and the concave and convex walls define a tip region of the airfoil portion and at least one cavity within the airfoil portion . at least a first ply is formed that contains a precursor of a ceramic - based material , and the first ply at least partially closes the cavity at the tip region of the airfoil portion . the airfoil portion material and the first ply are then cured so that the first ply forms a tip cap that closes the cavity and the precursors of the airfoil portion material and first ply are converted to the ceramic - based materials thereof .
