Abstract
A fitting for connecting first and second components arranged at right angles to each other that includes a flange part, which extends in a first direction and has a first connection surface in contact with the first component, and which has at least one first connection hole formed by a bore of a first insert; and a base part, which extends in a second direction, perpendicular to the first direction, and has a second connection surface in contact with the second component, and which has at least one second connection hole formed by a bore of a second insert. The first insert is joined to the second insert by at least one loop of continuous fiber tow wound around radially outer surfaces of the first insert second inserts.

A fitting adapted to connect a first component to a second component, which is at a right angle relative to the first component, the fitting comprises:
- a first insert defining a first insert bore;
- a second insert defining a second insert bore;
- a flange part, which extends in a first direction and has a first connection surface adapted to be in contact with the first component, the first insert being located in the flange part such that a first connection hole through the flange part is formed by the first insert bore;
- and a base part, which extends in a second direction, perpendicular to the first direction, and has a second connection surface adapted to be in contact with the second component, the second insert being located in the base part such that a second connection hole through the base part is formed by the second insert bore,
- wherein a main body of the fitting is made of a fiber-reinforced polymer material that is molded around the first and second inserts,
- wherein the first insert is joined to the second insert by one or more loops of a continuous fiber tow that is wound around part of a radially outer surface of the first insert and around part of a radially outer surface of the second insert, the continuous fiber tow extends generally in the first direction within the flange part of the fitting and extends generally in the second direction within the base part and follows a curved path within a transition zone between the flange part and the base part, and
- wherein the radially outer surface of the second insert curves away from the second connection surface at each side of a bore axis when viewed in a third direction.
A fitting adapted to connect a first component to a second component, which is at a right angle relative to the first component, the fitting comprises:
- a first insert defining a first insert bore;
- a second insert defining a second insert bore;
- a flange part, which extends in a first direction and has a first connection surface adapted to be in contact with the first component, the first insert being located in the flange part such that a first connection hole through the flange part is formed by the first insert bore;
- and
- a base part, which extends in a second direction, perpendicular to the first direction, and has a second connection surface adapted to be in contact with the second component, the second insert being located in the base part such that a second connection hole through the base part is formed by the second insert bore,
- wherein a main body of the fitting is made of a fiber-reinforced polymer material that is molded around the first and second inserts,
- wherein the first insert is joined to the second insert by one or more loops of a continuous fiber tow that is wound around part of a radially outer surface of the first insert and around part of a radially outer surface of the second insert, the continuous fiber tow extends generally in the first direction within the flange part of the fitting and extends generally in the second direction within the base part and follows a curved path within a transition zone between the flange part and the base part, wherein an upper surface of the base part of the fitting, opposite from the second connection surface, has a concave profile when viewed in a third direction and wherein at a flange side of the base part, the upper surface of the base part has a first curvature with a center of curvature that coincides with that of the curved path followed by the continuous fiber tow in the transition zone.
A fitting adapted to connect a first component to a second component, which is at a right angle relative to the first component, the fitting comprises:
- a first insert defining a first insert bore;
- a second insert defining a second insert bore;
- a flange part, which extends in a first direction and has a first connection surface adapted to be in contact with the first component, the first insert being located in the flange part such that a first connection hole through the flange part is formed by the first insert bore;
- and a base part, which extends in a second direction, perpendicular to the first direction, and has a second connection surface adapted to be in contact with the second component, the second insert being located in the base part such that a second connection hole through the base part is formed by the second insert bore,
- wherein a main body of the fitting is made of a fiber-reinforced polymer material that is molded around the first and second inserts,
- wherein the first insert is joined to the second insert by one or more loops of a continuous fiber tow that is wound around part of a radially outer surface of the first insert and around part of a radially outer surface of the second insert, the continuous fiber tow extends generally in the first direction within the flange part of the fitting and extends generally in the second direction within the base part and follows a curved path within a transition zone between the flange part and the base part, wherein at a second side of the base part distal from the flange part a concave upper surface of the base part has a second curvature and wherein the continuous fiber tow extends into the second side, following a curved path with a center of curvature that coincides with that of the second curvature.
