发明名称 METHOD FOR PRECISION PREFORMING OF COMPLEX COMPOSITE ARTICLES
摘要 <p>An apparatus and method provide for the assembly of a multiply shaped fiber preform, the apparatus using a shaping tool having the shape of the desired part, and one or more secondary location tools, can be positioned on the shaping tool, so as to simulate a flat shape. The location tools include a number of upwardly extending location pins, such that a number of plies can be assembled in a vertical stack using the pins to assure ply to ply accuracy and orientation. After assembly, the plies are engaged in a localized portion of the assembly so as to hold the plies in register, with the secondary tools then removed and the plies then formed to shape over the tool surfaces. Utilizing the apparatus and method of the invention maintains multiple plies in register during the assembly and forming process to assure part reproducibility, in an automated process.</p>
