Show how the supplier\u2019s L, W and thickness directions relate to the carbon fiber panel drawing. Core density and cell size do not communicate that orientation, and the skin fiber direction is a separate part of the construction.<\/p><h2>Use the core manufacturer\u2019s convention<\/h2><p>Hexcel\u2019s honeycomb selector guide identifies L, W and thickness directions. Retain the convention used for the selected core product instead of guessing it from a small photograph of the cells. The required orientation belongs on the core layout or another controlled construction reference.<\/p><h2>Relate the core to the panel axes<\/h2><p>Mark the intended panel length and width alongside the core arrows. Include the orientation of separate core pieces if a panel contains more than one. Rotating a core blank to save material should remain a visible construction change when the orientation is specified.<\/p><h2>Keep directional data attached<\/h2><p>When a core datasheet lists directional properties, preserve their labels in the review. Do not transfer one column into a general claim for every panel direction. The completed sandwich also includes skins, joints and local features. A clear core layout supports the material discussion without substituting for the design and acceptance evidence of the finished panel.<\/p><figure><a href=\"https:\/\/www.carbon-fiber-corp.com\/wp-content\/uploads\/2026\/10\/ly-geo-20261025-b03-03-honeycomb-2.webp\" aria-label=\"Open the full-size diagram\"><img src=\"https:\/\/www.carbon-fiber-corp.com\/wp-content\/uploads\/2026\/10\/ly-geo-20261025-b03-03-honeycomb-2.webp\" alt=\"Core orientation and skin reinforcement direction are recorded separately in the sandwich section.\" width=\"1600\" height=\"1000\" loading=\"lazy\" decoding=\"async\"><\/a><figcaption>Core orientation and skin reinforcement direction are recorded separately in the sandwich section. <a href=\"https:\/\/www.carbon-fiber-corp.com\/wp-content\/uploads\/2026\/10\/ly-geo-20261025-b03-03-honeycomb-2.webp\">View full size<\/a>.<\/figcaption><\/figure><aside class=\"notes\"><h2>Keep these details together<\/h2><ul><li>Core product and manufacturer axes<\/li><li>Relationship to panel axes<\/li><li>Orientation of each core piece<\/li><li>Direction labels on referenced data<\/li><\/ul><\/aside><p>Further reading: <a href=\"https:\/\/www.hexcel.com\/wp-content\/uploads\/2026\/01\/HexWeb_SelectorGuide_2017.pdf\">Hexcel: honeycomb configuration and direction labels<\/a>.<\/p><div class=\"reading\"><p>Related: <a href=\"https:\/\/www.carbon-fiber-corp.com\/sandwich-core-density-panel-stiffness\/\">Sandwich Core Density Alone Does Not Define Panel Stiffness<\/a> \u00b7 <a href=\"https:\/\/www.carbon-fiber-corp.com\/carbon-fiber-grade-tow-labels-t300-t700s\/\">T300, T700S and 3K Carbon Fiber: Read the Grade and Tow Labels Separately<\/a>.<\/p><p><a href=\"https:\/\/www.carbon-fiber-corp.com\/contact\/\">Discuss your component with Litian Yunde<\/a> \u00b7 <a href=\"https:\/\/www.carbon-fiber-corp.com\/carbon-fiber-guides\/\">Browse the component guides<\/a><\/p><\/div><\/div><script type=\"application\/ld+json\" class=\"ly-article-schema\">{\"@context\": \"https:\/\/schema.org\", \"@type\": \"BlogPosting\", \"@id\": \"https:\/\/www.carbon-fiber-corp.com\/carbon-fiber-panel-honeycomb-l-w-direction\/#article\", \"headline\": \"Honeycomb Core in Carbon Fiber Panels: Put L and W on the Layout\", \"description\": \"Mark honeycomb core L, W and thickness directions on carbon fiber panel layouts.
