The cuts help the core accommodate a shape, but they also change the represented construction. Include their direction, extent and treatment in the panel definition rather than specifying core density alone.<\/p><h2>Describe the supplied core format<\/h2><p>A plain board and a cut or grooved format are not the same supplied item. Identify the manufacturer\u2019s material, thickness and format. Show the intended cut direction in relation to the panel curvature. Avoid treating an image of a bendable core as a complete production definition.<\/p><h2>Review the proposed processing<\/h2><p>Diab\u2019s finishing information distinguishes core cuts, grooves and perforations by their intended form and flow roles. Use the instructions applicable to the chosen material. Where the construction includes filled cuts or additional bonding material, ask how that is represented in the proposed panel and mass estimate. This article gives no universal resin allowance.<\/p><h2>Keep the sample construction reproducible<\/h2><p>A curved panel sample should retain its core-format and orientation reference alongside the skins and process proposal. If the cut pattern changes, review the construction instead of approving it as a cosmetic difference. Agree inspection of the resulting panel under its actual requirements. Core density remains useful information, but it cannot stand in for the complete skin, core and cut-pattern definition.<\/p><figure><a href=\"https:\/\/www.carbon-fiber-corp.com\/wp-content\/uploads\/2026\/10\/ly-geo-20261024-11-kerf-2.webp\" aria-label=\"Open the full-size diagram\"><img src=\"https:\/\/www.carbon-fiber-corp.com\/wp-content\/uploads\/2026\/10\/ly-geo-20261024-11-kerf-2.webp\" alt=\"Core format and cut direction remain connected to the panel skins and sample identity.\" width=\"1600\" height=\"1000\" loading=\"lazy\" decoding=\"async\"><\/a><figcaption>Core format and cut direction remain connected to the panel skins and sample identity. <a href=\"https:\/\/www.carbon-fiber-corp.com\/wp-content\/uploads\/2026\/10\/ly-geo-20261024-11-kerf-2.webp\">View full size<\/a>.<\/figcaption><\/figure><aside class=\"notes\"><h2>Useful information for an enquiry<\/h2><ul><li>Core material, thickness and supplied format<\/li><li>Cut pattern and direction relative to curvature<\/li><li>Proposed filling or bonding scope<\/li><li>Sample construction and revision<\/li><\/ul><\/aside><p>Further reading: <a href=\"https:\/\/www.diabgroup.com\/products-services\/finishing\/\">Diab: core finishing, cuts, grooves and perforations<\/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-fibre-ballooned-drawing-inspection-map\/\">Ballooned Carbon Fibre Drawings: Map Each Callout to the Inspection Record<\/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\/kerf-cut-sandwich-core-panel-definition\/#article\", \"headline\": \"Kerf-Cut Sandwich Cores: Include the Cuts in the Panel Definition\", \"description\": \"Specify cut pattern and direction for a kerf-cut sandwich core.
