Patent ID: 7866969

Claim:
A mold assembly for generating a composite part from a strengthener in a generally solid phase and a matrix in a generally liquid phase; said mold assembly comprising: a) a base mold including a strengthener chamber for receiving the strengthener, a matrix injection inlet for injecting the matrix into said strengthener chamber and an evacuation outlet, said inlet and said outlet defining a propagation direction; b) a cover mold including a compression chamber defining a compression wall and a fluid aperture for injecting a controlling fluid into said compression chamber; said cover mold configured to be sealingly mounted to said base mold whereby said strengthener chamber and said compression chamber are adjacent; and c) a deformable member defining the boundary between said strengthener chamber and said compression chamber, said deformable member configured to pressurize the matrix toward the strengthener and propagate the matrix along said propagation direction upon compression exerted on said deformable member by the controlling fluid, wherein said compression chamber is divided into a first pressure region and a second pressure region by said deformable member when the matrix is injected into said strengthener chamber and when said controlling fluid is injected into said compression chamber.
