A mold core (and method for making same), for a concrete product mold comprising a mold core wall shaped to extend from a mold surface into an interior of the mold, preventing concrete from filling an area of the mold interior when the mold core is installed on the mold surface, the mold core wall comprising welded-together steel wire.

The concrete garden bed mold is plastic mold that creates concrete walls for a garden bed. An objective of the concrete garden bed mold is to provide users with a mold that easily releases the concrete block once cured within the mold. The concrete garden bed mold intends to provide users with a device that can create concrete molds with cylindrical holes to allow for a securing rebar to traverse through the concrete, securing the wall in place. To accomplish this the concrete garden bed mold has a mold cavity, a flat top surface, and tapered walls. The tapered walls ensure the created interlocking garden bed wall does not get stuck within the mold cavity as the concrete cures.

A method for forming a hole within a ceramic matrix composite component includes forming a first core portion for a ceramic matrix composite component; embedding a hollow member into the first core portion at a desired location; wrapping the first core portion with a first ceramic matrix composite material; inserting a rod through the hollow member and into the first core portion; removing the hollow member; assembling a second core portion to the first core portion such that the rod extends into the second core portion; and wrapping the first core portion and the second core portion with a second ceramic matrix composite material.
