Method for eliminating wrinkles or bridging in composite laminate corners or bends

A method of manufacturing a composite part having a curved or radiused corner to avoid wrinkling or bridging of outer-most composite plies during consolidation and cure, including laying up composite material on male or female tooling to form two flanges extending at a first angle relative each other and a curved or radiused corner extending between the two flanges. Then the method may include changing an orientation of one or both of the flanges of the composite material, such that the two flanges extend at a second included angle relative each other. The second included angle is smaller than the first angle. The method may also include a step of consolidating the composite material before, after, or during the step of changing the orientation of the composite material to the second angle, as well as a step of curing the composite material oriented at the second angle.

System and method for forming stacked materials

A system for forming stacked material includes a housing defining an interior space. The housing includes a bottom wall and a side wall coupled to the bottom wall. At least one tool is configured to shape the stacked material. The at least one tool is disposed within the interior space. A membrane extends at least partially over the bottom wall and is spaced a distance from the bottom wall. The membrane is configured to move towards the bottom wall. At least one intensifier mechanism is disposed in the interior space and is configured to induce a force against a portion of the stacked material and against the at least one tool as the membrane is moved towards the bottom wall.

Forming a profiled prepreg component

A shaping device for producing a profiled component includes a lay-on unit, a press-on unit and a pressure application unit. The lay-on unit has a support surface for laying on a semi-finished product to be shaped. The press-on unit presses a semi-finished product to be shaped onto the support surface. The pressure application unit has, at least on the side that faces the semi-finished product, a bendable shell for lying on the semi-finished product in an unshaped first state and for lying thereon in a shaped second state, as well as a pressure-transmitting and deformable filling. The pressure application unit can be arranged between the press-on unit and a semi-finished product to be shaped. The press-on unit has a bendable surface lying on the pressure application unit, which bendable surface transmits the force for the shaping onto the pressure application unit. The semi-finished product to be shaped may be a fibre-reinforced composite material.
