COMPRESSION TOOL AND METHOD OF FORMING GAS TURBINE ENGINE COMPONENTS

An assembly for forming a gas turbine engine according to an example of the present disclosure includes, among other things, a layup tool including a main body extending along a longitudinal axis and a flange extending radially from the main body, the flange defining an edge face slopes towards the main body to an axial face. At least one compression tool has a tool body having a first tool section and a second tool section extending transversely from the first tool section. The first tool section is translatable along a retention member in a first direction substantially perpendicular to the edge face such that relative movement causes the second tool section to apply a first compressive force on a composite article trapped between the axial face of the flange and the second tool section. A method of forming a gas turbine engine component is also disclosed.

Additive manufactured structure having a plurality of layers in a stacking direction that define a plurality of interfaces and method for making the same

An additive manufactured structure and methods for making and using same. The structure includes a plurality of layers stacked in a stacking direction. The structure further includes at least one reinforcement structure affixed to the layers and extending at least partially in the stacking direction. The reinforcement structure can hold the layers together to stiffen and strengthen the structure. Mechanical strength of the structure in the stacking direction can advantageously be improved. Shape and spatial distribution of the reinforcement structure can be customized and adapted to the geometry of the layers to enhance strengthening effect. The reinforcement structure can be tension free or have a compressive stress induced by a preload applied during manufacturing. The compressive stress can be adjusted dynamically via a sensor. The structure and methods provide, among other things, novelty for addressing the inherent weaknesses in parts created by large-scale extrusion deposition processes.

Thermoplastic Composite Having One or More Inner Openings and Method for Moulding Said Composite
20230070857 · 2023-03-09 ·

The present invention relates to a method and mold (100, 110) for forming a thermoplastic composite (1) that has one or more inner openings (0). The present invention further relates to a thermoplastic composite (1) manufactured using such method. Typically, forming of a thermoplastic composite (1) is achieved using a mold (100, 110) comprising a first (100) and second (110) mold part that are moved towards each other for the purpose of forming the thermoplastic composite (1). According to the invention, the mold further comprises a third mold part (120) that is movably arranged around the one or more first mold parts (100). Furthermore, an additional step is used of clamping the outer part in between the second and third mold parts during the mutual movement of the first and second mold parts while allowing the one or more inner parts to move relative to the one or more first mold parts thereby increasing the one or more inner openings, respectively.
