Carbon Fiber - 0210 Damage & Defects Delamination

Delamination in Carbon Fiber Bicycles

Delamination is a common form of damage in carbon fiber bicycle frames and components. It occurs at the interface between the layers of the laminate or along the bond line between two elements. This separation compromises the structural integrity and performance of the material, making it a critical issue in high-stress applications like cycling.

Delaminations can result from various factors:

• Stress Concentrations: Areas like laminate edges, radii, or ply drops are particularly vulnerable.
• Matrix Cracks: These can propagate through the material and lead to layer separation.
• Structural Details: Design features such as sharp angles or abrupt transitions can exacerbate stress and lead to delamination.
• Manufacturing Defects: Poor processing during production can create weak bonds between layers.
• Low-Energy Impacts: Even minor collisions or mishandling can initiate delamination, which may not be immediately visible.

Delaminations reduce the strength and stiffness of the bicycle frame, potentially leading to failure under load. Regular inspections and high-quality manufacturing processes are essential to mitigate this issue and maintain the safety and performance of carbon fiber bicycles.
