Abstract
A fiber composite structure includes a base structure being formed of a first fiber composite material that includes first fiber bundles embedded in a first matrix material, wherein the base structure includes an opening defined by first fiber bundles which include first sections and a second section that continuously or uninterruptedly interconnects the first sections, wherein the second section forms a bay that defines a part of the circumference of the opening. The fiber composite structure further includes a functional structure positioned in the opening of the base structure and joined with the first fiber composite material of the base structure.
Claims17
A fiber composite structure, comprising:
- a base structure comprising:
- a first fiber composite material that includes first fiber bundles embedded in a first matrix material;
- and
- an opening defined by the first fiber bundles;
- wherein a portion of the first fiber bundles each comprise first sections that are on opposite sides of the opening, the first sections that are on opposite sides of the opening extending away from each other and away from the opening in opposite directions;
- wherein the portion of the first fiber bundles each comprise a second section that passes circumferentially around the opening and forms a bay that defines a part of a circumference of the opening;
- and
- wherein the second section continuously or uninterruptedly interconnects the first sections of a same fiber in the portion of the first fiber bundles;
- and
- a functional structure positioned in the opening of the base structure and joined with the first fiber composite material of the base structure.
A method for manufacturing a fiber composite structure, comprising:
- preparing a base structure, which comprises first fiber bundles embedded in a first matrix material, by positioning the first fiber bundles to define an opening, wherein:
- a portion of the first fiber bundles each comprise first sections that are on opposite sides of the opening, the first sections that are on opposite sides of the opening extending away from each other and away from the opening in opposite directions:
- the portion of the first fiber bundles each comprise a second section that passes circumferentially around the opening and forms a bay that defines a part of a circumference of the opening;
- and
- the second section continuously or uninterruptedly interconnects the first sections of a same fiber in the portion of the first fiber bundles;
- positioning a functional structure within the opening of the base structure;
- and
- joining the functional structure and the base structure by curing the first matrix material, in which the first fiber bundles are embedded.
A fiber composite structure, comprising:
- a base structure being formed of a first fiber composite material that includes first fiber bundles embedded in a first matrix material, wherein the base structure comprises an opening defined by first fiber bundles which include first sections and a second section that continuously or uninterruptedly interconnects the first sections, wherein the second section forms a bay that defines a part of the circumference of the opening;
- and
- a functional structure positioned in the opening of the base structure and joined with the first fiber composite material of the base structure;
- wherein the functional structure includes a solid body;
- and
- wherein:
- the functional structure includes a solid body;
- or
- the solid body is made of a material that has, in a predefined frequency range, a higher electromagnetic transmittance than the first fiber composite material.
