High-Pressure Composite Gas Tank (Concept)

Create a parametric 3D CAD model (SolidWorks-style, units in mm) of a high-pressure composite gas storage tank with an internal ceramic layer. This is a CONCEPT model for a research project, not a certified pressure-vessel design. GEOMETRY (cylinder with hemispherical domes, axis along X): - Gas cavity: internal radius 300 mm, cylindrical section length 1368 mm, hemispherical domes (R 300 mm) at both ends. Cavity volume must be 500 litres and inner wetted surface about 3.7 m^2. Verify both and report them. - Layers, from the inside out (each layer an offset of the one inside it, modelled as a SEPARATE BODY so each can be shown, hidden or suppressed): 1. Ceramic inner layer: 3 mm thick (parameter ceramic_t, range 0.5 to 5 mm). 2. PA6 liner: 4 mm thick. 3. Carbon-fibre composite shell: 25 mm thick, outer surface smooth. - Resulting outer radius: 300 + 3 + 4 + 25 = 332 mm. Overall length about 2033 mm. - End boss at ONE dome: stainless-steel (or aluminium) boss, flange diameter about 120 mm, clamped between the liner and the composite shell, with a central threaded gas port (placeholder size G3/4). The second dome has no opening. - Working pressure 250 bar (25 MPa); mark it in the drawing notes only. MAKE IT PARAMETRIC with named parameters: cavity_radius, cyl_length, ceramic_t, liner_t, composite_t, boss_flange_d, port_size. Changing a parameter must rebuild the whole model. DELIVERABLES: 1. 3D model with a feature tree and the layers as separate bodies (colour them: ceramic = white, PA6 = yellow, carbon = dark grey, boss = steel). 2. A half-section view of the dome and boss region showing all layers. 3. A 2D drawing: front view, section view, detail of the boss region, overall dimensions, and layer thickness callouts. 4. A table of parameters, cavity volume, inner surface area, and volume of each layer. 5. Exports: STEP and STL. RULES: - If anything is unclear, list your assumptions at the end instead of inventing details silently. - Do not claim the design is structurally verified or certified.

Every value above is a live dimension. Open a model like this in the editor and each one becomes a slider you can drag before exporting.
