SYSTEM AND METHOD FOR FABRICATING A LAMINATE STRUCTURE
A method for fabricating a laminate structure includes providing a laminate core, forming at least one laminate layer on each opposing side of the laminate core, the laminate core and the at least one laminate layer on each opposing side of the laminate core forming a laminate structure, determining an out-of-plane displacement for the laminate structure at a temperature of interest, the out-of-plane displacement corresponding to warpage, and if the warpage exceeds a predetermined value, modifying at least one of the laminate layers to reduce the warpage.
1 . A method for fabricating a laminate structure, comprising:
providing a laminate core;
forming at least one laminate layer on each opposing side of the laminate core, the laminate core and the at least one laminate layer on each opposing side of the laminate core forming a laminate structure;
determining an out-of-plane displacement for the laminate structure at a temperature of interest, the out-of-plane displacement corresponding to warpage; and
if the warpage exceeds a predetermined value, modifying at least one of the laminate layers to reduce the warpage.
2 . The method of claim 1 , wherein the modifying further comprises altering at least one layer property.
3 . The method of claim 2 , wherein the layer property is chosen from thickness, area percent composition of multiple material layers, the geometry of the layers, and the material of the layers.
4 . The method of claim 3 , wherein the at least one laminate layer on each opposing side of the laminate core comprises a composite layer having at least two different materials.
5 . The method of claim 4 , wherein the two different materials comprise a dielectric material and a metal material, the metal material being applied as a repeating unit cell pattern.
6 . The method of claim 5 , wherein a repeating unit cell on the at least one laminate layer on each opposing side of the laminate core is different than a repeating unit cell on another of the at least one laminate layer on each opposing side of the laminate core.
7 . A system for fabricating a laminate structure, comprising:
a laminate core having at least one laminate layer on each opposing side of the laminate core, the laminate core and the at least one laminate layer on each opposing side of the laminate core forming a laminate structure;
a software module executing on a processor, the software module determining an out-of-plane displacement for the laminate structure at a temperature of interest, the out-of-plane displacement corresponding to warpage; and
if the warpage exceeds a predetermined value, the software module modifying at least one of the laminate layers to reduce the warpage.
8 . The system of claim 7 , wherein the modifying further comprises altering at least one layer property.
9 . The system of claim 8 , wherein the layer property is chosen from thickness, area percent composition of multiple material layers, the geometry of the layers, and the material of the layers.
10 . The system of claim 9 , wherein the at least one laminate layer on each opposing side of the laminate core comprises a composite layer having at least two different materials.
11 . The system of claim 10 , wherein the two different materials comprise a dielectric material and a metal material, the metal material being applied as a repeating unit cell pattern.
12 . The system of claim 11 , wherein a repeating unit cell on the at least one laminate layer on each opposing side of the laminate core is different than a repeating unit cell on another of the at least one laminate layer on each opposing side of the laminate core.
13 . A method for fabricating a laminate structure, comprising:
providing a laminate core;
forming at least one laminate layer on each opposing side of the laminate core, the laminate core and the at least one laminate layer on each opposing side of the laminate core forming a laminate structure;
determining an out-of-plane displacement for the laminate structure at a temperature of interest, the out-of-plane displacement corresponding to warpage; and
if the warpage exceeds a predetermined value, modifying a layer property of at least one of the laminate layers to reduce the warpage, the layer property chosen from thickness, area percent composition of multiple material layers, the geometry of the layers, and the material of the layers.
14 . The method of claim 13 , wherein the at least one laminate layer on each opposing side of the laminate core comprises a composite layer having at least two different materials.
15 . The method of claim 14 , wherein the two different materials comprise a dielectric material and a metal material, the metal material being applied as a repeating unit cell pattern.
16 . The method of claim 15 , wherein a repeating unit cell on the at least one laminate layer on each opposing side of the laminate core is different than a repeating unit cell on another of the at least one laminate layer on each opposing side of the laminate core.
