Composite laminate structure
View Patent ↗A composite laminate structure includes a first skin; a second skin; a core between the first skin and the second skin, the core including adjacent core sections and a Z-Y partition separating the adjacent core sections; and a plurality of distinct groupings of Z-axis fibers that extend from the first skin to the second skin through the adjacent core sections and the Z-Y partition separating the adjacent core sections.
1. A composite laminate structure, comprising:
a first skin;
a second skin;
a core between the first skin and the second skin, the core including adjacent core sections and a Z-Y partition separating the adjacent core sections; and
a plurality of distinct groupings of Z-axis fibers that extend from the first skin to the second skin through the adjacent core sections and the Z-Y partition separating the adjacent core sections.
2. The composite laminate structure of claim 1 , wherein the groupings of Z-axis fibers are generally perpendicular to the first skin and the second skin.
3. The composite laminate structure of claim 1 , wherein the ends of the Z-axis fibers extend into the first skin and second skin.
4. The composite laminate structure of claim 1 , wherein the first skin and the second skin comprise an X-Y material.
5. The composite laminate structure of claim 1 , wherein the adjacent core sections are made of foam.
6. The composite laminate structure of claim 1 , wherein the Z-Y partition extends substantially at 45 degrees relative to horizontal.
7. The composite laminate structure of claim 1 , wherein the adjacent core sections include respective portions vertically disposed relative to each other and separated by the Z-Y partition, and the plurality of distinct groupings of Z-axis fibers extend from the first skin to the second skin through the respective vertically disposed sections and the Z-Y partition separating the vertically disposed sections.
8. The composite laminate structure of claim 1 , wherein the first skin and the second skin comprise glass fibers.
9. The composite laminate structure of claim 1 , wherein the Z-Y partition comprises glass fibers.
10. The composite laminate structure of claim 1 , wherein the core sections are longitudinally elongated and have a polygonal cross-section.
11. The composite laminate structure of claim 10 , wherein the core sections include a combination of polygonal and half polygonal core sections that combine to form a substantially planar core.
12. The composite laminate structure of claim 1 , wherein the composite laminate structure includes a shear modulus of at least 35,000 psi.
13. The composite laminate structure of claim 1 , wherein the composite laminate structure includes a plurality of respective, separate Z-Y partitions between respective adjacent core sections.
14. The composite laminate structure of claim 1 , wherein the Z-Y partition extends in a +Z direction and a +Y direction.
15. The composite laminate structure of claim 1 , wherein the Z-Y partition extends in a +Z direction and a −Y direction.
16. The composite laminate structure of claim 1 , wherein the Z-axis fibers wick liquid resin when the composite laminate structure is subjected to liquid resin, aiding the cured integrity of the entire composite laminate structure.
17. The composite laminate structure of claim 1 , wherein the Z-Y partition includes one or more Z-Y partitions, the one or more Z-Y partitions including end portions that overlap adjacent to the first skin and the second skin to form a localized thicker skin.
