Description
Technical Field
The invention belongs to a method for forming a J-shaped wall part with a closed composite material strip, which is suitable for laying, forming and demolding the J-shaped wall part made of the composite material, ensures the angle requirement of laying each part of a prepreg of the composite material, improves the operability of laying the J-shaped wall part, and ensures smooth demolding and stable internal quality after the part is manufactured.
Background
The forms of the composite material added with the ribs mainly comprise T-shaped stringers, J-shaped walls, I-shaped stringers and omega-shaped stringers. The I-shaped truss has relatively high and narrow cross section size and large difference of inertia moment between two main shafts of the cross section, and can only be directly used for a bent member in a web plate plane or a stressed member forming a square grid structure, but is not suitable for an axial compression member or a member which is perpendicular to the web plate plane and is also bent. The J-shaped wall and the omega stringer do not have the corresponding problem of different inertias, wherein the J-shaped high wall can also be used as a connecting member of two wall plates, and the J-shaped wall has good stability and can also be used as a connecting piece, so that the frequency of the J-shaped wall in composite parts is higher and higher.
The J-wall component is generally divided into three sections, namely, Z-shaped, C-shaped, and I-shaped, as shown in fig. 1. The general flow of the laying and forming process of the J-shaped wall is as follows: 1. three sets of independent tooling are manufactured for respectively laying three parts on the J-shaped wall. The tooling may be of a mould type or a frame type structure according to different sizes of parts, and the material may be common steel or invar steel; 2. combining the laid parts together by taking one set as a reference, and fixing to ensure that the positions of the parts are not changed in the curing process; 3. and (4) splitting the cured and molded workpiece to take out the part. The tools for laying several parts in the large J-shaped wall are difficult to be combined and positioned through the tools due to large weight in the combination process, and the prefabricated body which is singly laid cannot be positioned due to over-softness. If the J-shaped wall is provided with a closed opening, the conventional tool structure is difficult to demold, and the violent demolding easily causes damage to the content of the part. Three parts after being combined together are solidified, and defects can be generated due to uneven pressure transmission in the solidification process because the parts are all metal tools. Therefore, what kind of tool structure can be adopted to ensure that the laying, forming and demolding of the large-scale J-shaped wall part with the closing-in are smoothly carried out becomes a key technology for manufacturing the large-scale J-shaped wall with the closing-in.
