Fiber Composite Hollow Profile with Partial Bulkhead

The reinforcing bulkhead is designed with varying height along its length, with the height being less than the passage height only at specific points rather than uniformly. This local variation provides mechanical reinforcement exactly where needed while preserving passage clearance in other areas, thus resolving the contradiction between strength enhancement and space conservation

Instead of providing full-height reinforcement along the entire bulkhead, the invention applies reinforcement partially - the bulkhead height is less than passage height at specific points but may equal or exceed it at other points. This partial action achieves the necessary mechanical stability while avoiding excessive space consumption

The bulkhead height varies locally along its length, being less than passage height at specific points. This creates non-uniform reinforcement that provides maximum rigidity where structurally necessary while reducing material usage and weight in less critical areas

The height parameter of the reinforcing bulkhead is changed along its length rather than maintaining a constant full-height design. By varying this geometric parameter, the structure achieves optimal rigidity-to-weight ratio by concentrating material where it provides the most structural benefit

The reinforcing bulkhead is integrated into the hollow profile during the initial braiding process rather than being added through subsequent milling, drilling, or gluing operations. This preliminary action of incorporating reinforcement into the base structure eliminates the need for complex downstream manufacturing steps

The reinforcing bulkhead and hollow profile are merged into a single integrated component produced by the braiding process. This combining of reinforcement and structure into one manufacturing step simplifies the overall production process and eliminates multiple separate operations

The braiding process inherently produces minimal waste through its continuous fiber reinforcement method, eliminating the need for extensive trimming and material removal that characterizes shell construction. The process serves itself by naturally achieving the desired component shape and reinforcement without generating significant waste

The manufacturing method transitions from shell construction with high material removal to braiding with continuous fiber placement. This parameter change in the manufacturing process fundamentally alters the waste profile while maintaining the weight benefits of fiber-reinforced plastics
