Example Embodiment

[0037] Examples: In order to have a clearer understanding of the process features, objectives and effects of the present invention, specific implementations of the present invention will now be described with reference to the drawings.

[0038] figure 1 It is a schematic diagram of the connection structure between the bottom mold 1 and the filling mold 3. The filling mold 3 is fixed on the bottom mold 1 by bolts 4 to form a grid channel for laying fiber tows. A positioning card 2 is provided on the center line of the channel, and the diameter of the positioning card 2 cannot be less than 0.5 cm, in order to protect the tight fibers from being broken when turning corners.

[0039] figure 2 It is a schematic diagram of the laying of the fiber tow 5 in the channel. The fiber tows 5 are laid at intervals in the longitudinal and weft directions in the channels formed by the array arrangement of the filling mold 3, and the continuous and tight laying is always maintained.

Abstract

The invention discloses a forming mold and a forming method of a fiber reinforced composite material grid rib. The forming mold comprises a bottom mold, filling molds, compression strips and positioning clamps. The forming method comprises the steps of spreading fiber tows on the mold in longitude and latitude directions to form a fiber grid, and carrying out vacuumizing by virtue of a vacuum mold pressing technique so as to finish dipping and curing forming of the fiber grid. According to the forming mold and the forming method, the fiber reinforced composite material grid rib with any grid size can be fabricated according to the requirement, has a precise size and is stable in performance, and the machining process is environmentally friendly, is easy to handle and is suitable for industrial batch production.

Description

technical field [0001] The invention relates to special equipment and a method for forming composite materials, in particular to a fiber-reinforced composite material grid rib forming mold and a forming method. Background technique [0002] Fiber-reinforced composite grid reinforcement is an overall composite material that impregnates high-performance continuous fibers such as carbon fiber, glass fiber, and basalt fiber in epoxy resin, unsaturated polyester resin, and vinyl resin to form a grid. This fiber-reinforced composite grid bar has the advantages of light weight, high strength, two-way force, convenient construction, and is suitable for ordinary and harsh environments. It can overcome the shortcomings of traditional building materials and has more application advantages. The specific performance exist: [0003] The grid reinforcement made of fiber-reinforced composite material has the reinforcement effect in two directions at the same time, which can be easily appli...
