Abstract
In accordance with one embodiment of the present disclosure, a method for manufacturing a honeycomb core sandwich panel includes placing a thermoset facesheet in contact with a thermoplastic honeycomb core without using a separate adhesive and attaching the thermoset facesheet to the thermoplastic honeycomb core by using a curing profile comprising a temperature that is lower than a gel point temperature of the thermoset facesheet and higher than a softening point temperature of the thermoplastic honeycomb core.
Claims21
-40. (canceled)
An apparatus, comprising:
- a thermoset facesheet;
- and
- a thermoplastic core, wherein the thermoplastic core has a deformation zone;
- wherein the thermoset facesheet is attached to the thermoplastic core using a curing profile and wherein the curing profile comprises curing the thermoset facesheet and the thermoplastic core at a same time and at a same temperature.
An apparatus, comprising:
- a thermoset facesheet;
- and
- a thermoplastic core, wherein the thermoplastic core comprises a plurality of cells, the cells comprising:
- cell walls;
- and
- a void;
- wherein the thermoset facesheet is attached to the thermoplastic core using a curing profile;
- wherein the curing profile comprises curing the thermoset facesheet and the thermoplastic core at a same time and at a same temperature;
- and wherein a thickness of the cell walls measured at an interface of the thermoset face sheet and the thermoplastic core is greater than at a midplane of the cells.
An apparatus, comprising:
- a first thermoset facesheet;
- a second thermoset facesheet;
- and
- a thermoplastic core, wherein the thermoplastic core comprises as plurality of cells, the cells comprising:
- cell walls;
- a void;
- a longitudinal axis perpendicular to a midplane of the first thermoset facesheet;
- and
- wherein the first thermoset facesheet is attached to the thermoplastic core using a curing profile and without using a separate adhesive disposed between the first thermoset facesheet and the thermoplastic core;
- wherein the second thermoset facesheet is attached to the thermoplastic core using the curing profile and without using a separate adhesive disposed between the second thermoset facesheet and the thermoplastic core;
- wherein the curing profile comprises curing the first thermoset facesheet, the second thermoset facesheet, and the thermoplastic core at a same time and at a same temperature;
- and
- wherein a thickness of the cell walls measured at an interface of first thermoset facesheet or the second thermoset facesheet and the thermoplastic core is greater than at the midplane of the cells.
