AI Technical Summary
The existing pultrusion beam sheet process cannot effectively meet the quality standard requirements, resulting in excessive gaps in the pultruded beams and delays in production.
The sheet material is sliced, bundled, bonded, and fixed. In particular, cotton thread is used to tie it three times at the root and tip of the pultruded beam blade, and adhesive is applied to the tangential position. Fiberglass tape is used to adjust the gap to ensure that the sheet material is within the standard range of the mold closing gap. Finally, it is fixed with tooling clamps.
This reduces the layup adjustment time of the same layer of sheet metal in the pultruded beam, shortens the molding cycle, improves the quality of the blade, solves the problem of excessive gap in the pultruded beam, and ensures the overall safety and reliability of the blade.
