Mechanical Performance and Parameter Sensitivity Analysis of 3D Braided Composites Joints

Figure 14

The relative contribution of various parameters on the sensitivity of 𝑁. 𝑛: the ratio of pipe force and material strength, 𝛾: the ratio of main pipe diameter and thickness, 𝛽: the ratio of main pipe diameter and branch pipe diameter, 𝜃: branch pipe axis and main pipe axis angle (°) 𝜏: the ratio of main pipe wall thickness and branch pipe wall thickness, 𝛼: fiber braiding angle (°), 𝑉_𝑓: fiber volume content (%), and 𝑑: the main pipe diameter (mm).
