href=\"https:\/\/dycarbonfiber.com\/en\/carbon-fiber-components-manufacturer\/carbon-fiber-tube-manufacturers\/\"> <strong>T800 carbon fiber tube<\/strong><\/a> is an effective lightweight structural solution for wind tunnel model support applications that require high stiffness, low deflection, and stable performance under aerodynamic loading. For scaled-building wind tunnel tests, a custom roll-wrapped <a href=\"https:\/\/dycarbonfiber.com\/en\/carbon-fiber-components-manufacturer\/carbon-fiber-tube-manufacturers\/\">T800 carbon fiber tube<\/a> can function as a rigid cantilevered support strut, also known as a sting, supporting a PLA or other lightweight model while minimizing unwanted vibration.<\/p><p class=\"my-2 [&amp;+p]:mt-4 [&amp;_strong:has(+br)]:inline-block [&amp;_strong:has(+br)]:align-top\">This type of project requires more than selecting a strong carbon fiber grade. The final support performance depends on the tube diameter, wall thickness, unsupported length, laminate orientation, mounting condition, model weight, and aerodynamic test environment.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-6cd74cb3 e-flex e-con-boxed e-con e-parent\" data-id=\"6cd74cb3\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t\t\t\t<div class=\"e-con-inner\">\n\t\t\t\t<div class=\"elementor-element elementor-element-6166b5c9 elementor-widget elementor-widget-text-editor\" data-id=\"6166b5c9\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t\t\t\t\t\t<h2 id=\"project-requirements\" class=\"font-semibold leading-tight text-pretty mb-2 mt-4 [[data-has-inline-images]_&amp;]:clear-end text-lg first:mt-0 md:text-lg [hr+&amp;]:mt-4\">Project Requirements<\/h2><p class=\"my-2 [&amp;+p]:mt-4 [&amp;_strong:has(+br)]:inline-block [&amp;_strong:has(+br)]:align-top\">A customer required a <a href=\"https:\/\/dycarbonfiber.com\/en\/carbon-fiber-components-manufacturer\/carbon-fiber-tube-manufacturers\/\">round carbon fiber tube<\/a> for use as a fixed-base support strut in high-frequency aerodynamic testing of 1:400 scale building models.<\/p><p class=\"my-2 [&amp;+p]:mt-4 [&amp;_strong:has(+br)]:inline-block [&amp;_strong:has(+br)]:align-top\">The proposed tube requirements included:<\/p><ul class=\"marker:text-secondary list-disc pl-8\"><li class=\"py-0 my-0 prose-p:pt-0 prose-p:mb-2 prose-p:my-0 [&amp;&gt;p]:pt-0 [&amp;&gt;p]:mb-2 [&amp;&gt;p]:my-0\"><p class=\"my-2 [&amp;+p]:mt-4 [&amp;_strong:has(+br)]:inline-block [&amp;_strong:has(+br)]:align-top\">Application: Wind tunnel testing support for scaled building models<\/p><\/li><li class=\"py-0 my-0 prose-p:pt-0 prose-p:mb-2 prose-p:my-0 [&amp;&gt;p]:pt-0 [&amp;&gt;p]:mb-2 [&amp;&gt;p]:my-0\"><p class=\"my-2 [&amp;+p]:mt-4 [&amp;_strong:has(+br)]:inline-block [&amp;_strong:has(+br)]:align-top\">Support condition: Rigidly fixed at the base with the model mounted at the top<\/p><\/li><li class=\"py-0 my-0 prose-p:pt-0 prose-p:mb-2 prose-p:my-0 [&amp;&gt;p]:pt-0 [&amp;&gt;p]:mb-2 [&amp;&gt;p]:my-0\"><p class=\"my-2 [&amp;+p]:mt-4 [&amp;_strong:has(+br)]:inline-block [&amp;_strong:has(+br)]:align-top\">Tube length: 15\u201330 in \/ 381\u2013762 mm<\/p><\/li><li class=\"py-0 my-0 prose-p:pt-0 prose-p:mb-2 prose-p:my-0 [&amp;&gt;p]:pt-0 [&amp;&gt;p]:mb-2 [&amp;&gt;p]:my-0\"><p class=\"my-2 [&amp;+p]:mt-4 [&amp;_strong:has(+br)]:inline-block [&amp;_strong:has(+br)]:align-top\">Tube diameter: 2\u20133 in \/ 50.8\u201376.2 mm<\/p><\/li><li class=\"py-0 my-0 prose-p:pt-0 prose-p:mb-2 prose-p:my-0 [&amp;&gt;p]:pt-0 [&amp;&gt;p]:mb-2 [&amp;&gt;p]:my-0\"><p class=\"my-2 [&amp;+p]:mt-4 [&amp;_strong:has(+br)]:inline-block [&amp;_strong:has(+br)]:align-top\">Wall thickness: 1\/16\u20131\/8 in \/ approximately 1.6\u20133.2 mm<\/p><\/li><li class=\"py-0 my-0 prose-p:pt-0 prose-p:mb-2 prose-p:my-0 [&amp;&gt;p]:pt-0 [&amp;&gt;p]:mb-2 [&amp;&gt;p]:my-0\"><p class=\"my-2 [&amp;+p]:mt-4 [&amp;_strong:has(+br)]:inline-block [&amp;_strong:has(+br)]:align-top\">Surface requirement: Matte finish for friction-fit installation<\/p><\/li><li class=\"py-0 my-0 prose-p:pt-0 prose-p:mb-2 prose-p:my-0 [&amp;&gt;p]:pt-0 [&amp;&gt;p]:mb-2 [&amp;&gt;p]:my-0\"><p class=\"my-2 [&amp;+p]:mt-4 [&amp;_strong:has(+br)]:inline-block [&amp;_strong:has(+br)]:align-top\">Structure concept: Unidirectional internal layers with a twill weave outer layer<\/p><\/li><li class=\"py-0 my-0 prose-p:pt-0 prose-p:mb-2 prose-p:my-0 [&amp;&gt;p]:pt-0 [&amp;&gt;p]:mb-2 [&amp;&gt;p]:my-0\"><p class=\"my-2 [&amp;+p]:mt-4 [&amp;_strong:has(+br)]:inline-block [&amp;_strong:has(+br)]:align-top\">Priority: High bending stiffness and low vibration<\/p><\/li><\/ul><p class=\"my-2 [&amp;+p]:mt-4 [&amp;_strong:has(+br)]:inline-block [&amp;_strong:has(+br)]:align-top\">Because the tube works as a cantilever, the root end carries the highest bending moment.

For sting applications specifically, it&#8217;s worth being clear about what T800 actually improves: tensile strength gains are more significant than stiffness gains. If the strut&#8217;s main failure risk is bending or vibration rather than snapping under tension, wall thickness, layup structure, and tube geometry usually matter more than jumping to a higher fiber grade. A well-designed T800 carbon fiber tube can outperform a poorly laid-up T1000 tube in exactly this kind of stiffness-critical use case.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-4efb0375 e-flex e-con-boxed e-con e-parent\" data-id=\"4efb0375\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t\t\t\t<div class=\"e-con-inner\">\n\t\t\t\t<div class=\"elementor-element elementor-element-5d889f50 elementor-widget elementor-widget-text-editor\" data-id=\"5d889f50\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t\t\t\t\t\t<h2 id=\"recommended-tube-construction\" class=\"font-semibold leading-tight text-pretty mb-2 mt-4 [[data-has-inline-images]_&amp;]:clear-end text-lg first:mt-0 md:text-lg [hr+&amp;]:mt-4\">Recommended Tube Construction<\/h2><p class=\"my-2 [&amp;+p]:mt-4 [&amp;_strong:has(+br)]:inline-block [&amp;_strong:has(+br)]:align-top\">For a high-stiffness carbon fiber tube used as a wind tunnel model support, a roll-wrapped construction is recommended.
