Problem Statement: Design a submersible that has an internal volume of 1500cm3 and can withstand an external water pressure of 745KPa (depth of 250ft ). The material to be used is a short-fiber carbon-filled nylon matrix. The project entails designing the geometry, finding the build orientation such that the fibers are oriented in the intended direction, and the design performs well structurally. We will estimate the cost and time to print the part via additive manufacturing. Material Used: Nylon-x with 20% weight-fraction short fiber carbon composite. Use the following properties until an update is issued. \[ \text { E_11 }=3.29 \mathrm{GPA} ; \mathrm{E} \_22=2.0 \mathrm{GPa} \text {, nu_12 =0.3.G_12= } \] 908MPa SL+=S_L=70MPa,ST+=ST=37MPa,SLT=37MPa The report should contain technical descriptions of the design as follows: Section 1: Design the vehicle's shape - show the geometry dimensions to meet the internal volume condition. Use as streamlined a shape as possible. Specify the shape, size, and thickness of the vehicle. You can use a spherical front end, cylindrical middle and design as follows: Section 1: Design the vehicle's shape - show the geometry dimensions to meet the internal volume condition. Use as streamlined a shape as possible. Specify the shape, size, and thickness of the vehicle. You can use a spherical front end, cylindrical middle and conical tail as the shape. The diameters and lengths are to be determined according to the restrictions. You can make assumptions about any missing requirements and state them. Section 2: Material design -- Determine the material structure (i.e., composition and layup - what direction should the fibers be oriented? Determine the layer thicknesses - Use Solidworks Simulation to ascertain that the safety factor is at least 2. Use layer sizes as produced from process design. Section 3: Process Design - Use Cura to determine the print direction so the internal geometry is as close to the designed material as possible. If the internal geometry has voids, recompute the estimates for stiffness and strength based on void volume fraction. Describe your assumptions - Try to use close to 100% infill. Show the print orientation and layer-bylayer structure as seen from Cura. conical tail as the shape. The diameters and lengths are to be determined according to the restrictions.
