ABSTRACT:
A method and apparatus for producing a shaped composite article from a matrix material and a reinforcing material is disclosed wherein the composite article has predetermined physical and mechanical properties. As illustrated, the apparatus includes a matrix crucible (18) in which a matrix material is contained. A piston (30) is provided for maintaining and controlling the level of the matrix material (19) in the crucible (18) and for controlling the temperature of the matrix material by means of utilizing either a cooling coil (36) or a heating coil (40). A plurality of capillary tubes (26) are carried in a capillary plug (24) through which the reinforcing material is pulled during the process. Shape forming means includes a shape forming plate (42) having an opening (48) formed therein corresponding to the shape of the object being formed. The shape forming plate is spaced above the capillary plug (24) such that a level (44) of matrix material occupies the opening (48) in the forming plate to provide a contact zone above the capillary plug in which the matrix and reinforcing materials contact one another. This level is kept small so that interaction between the two materials is kept at a minimum.
