INSTALLATION vacuum infusion for manufacturing large bridge spans of composite materials

摘要

The invention relates to installations for the manufacture of vacuum infusion of large span bridges of composite materials. Installation for the manufacture of vacuum infusion of large span bridges composite manufacturing equipment to the working chamber of the matrix display, intended to receive the sandwich structures based on a middle layer covering the filler and its technological mat. Matrix-casing-head base is formed with a curved deflection in the direction of its longitudinal axis. The working surface of the bottom has a longitudinally oriented sides and connecting them cross. Rear bottom surface is mounted on parallel along the longitudinal axis of the cross pieces supports placed between the vertical studs, successively installed in the direction in parallel rows and having in said direction a variable height to form a curvilinear trough bottom according to the technological construction rise sandwich structure formed span of the bridge. The middle layer filler has U-shaped profile with the outer surface of each vertically oriented portion parallel to the facing inner surface corresponding thereto longitudinally-oriented sidewall. Each said surface of the sidewall located on the longitudinal axis of the bottom of the base at a distance L = 1 + a, the height of the sidewall exceeds the height of said portions of the middle layer and covering its technological mat, where 1 - distance from the longitudinal bottom axis to the outer surface of the vertically oriented portion of the middle layer, and - given the thickness of the mat process. Longitudinally oriented side walls have
