Problems solved by technology
Once it is formed, it can only be corrected and polished after curing, which will destroy the continuity of the fiber, and its overall performance will be discounted, which is not conducive to the stability of its structure and the guarantee of the mechanical properties of the product.
If the rigidity of the window frame is insufficient, it will cause deformation, which will affect the appearance gap and flatness; if the deformation is too large, it will affect the sealing performance of the sealing strip, causing noise and high-speed vibration problems
At the same time, the secondary operation increases various processes, increases the labor load, and increases the cost, especially for mass production, which brings many problems

The invention provides a composite material wrinkle eliminating tool and a manufacturing device and method thereof. The composite material wrinkle eliminating tool comprises shaping plates and a connecting belt arranged between the shaping plates; the shaping plates are enclosed by the connecting belt in a closed mode, the two ends of the connecting belt are both embedded into the shaping plates, and the surface of the connecting belt is coated with a polysulfide sealant. According to the eliminating tool and the manufacturing device and method thereof, smooth transition of cloth layers in the staggered positions of multiple specially-shaped surfaces can be well achieved, the problem of concentrated distribution of large cloth folds is solved, fiber breakage caused by follow-up grinding is reduced, the quality and stability of products are improved, and batch production is facilitated.
Description
technical field [0001] The invention belongs to the field of glass fiber reinforced plastics manufacturing, and in particular relates to a tool for eliminating wrinkles of composite materials and a manufacturing device and method thereof. Background technique [0002] Due to the unique advantages of high specific strength, high specific stiffness, strong designability, good fatigue fracture resistance, corrosion resistance, stable structural size and easy large-area integral molding, fiber-reinforced resin-based composite materials have been gradually promoted and applied to the body During the production of the shell structure. [0003] For example, in the integral molding method of a composite car body disclosed in Patent Notification No. CN111559091A, the car body shell mold has the characteristics of a large number of doors and windows, large curvature changes, many edges on special-shaped surfaces, and vertical depth, etc., and the number of reinforcing fiber layers at ...
