Guiding pultrusion mold for I-shaped glass fiber reinforced plastic sectional material

Abstract

The invention discloses a guiding pultrusion mold for an I-shaped glass fiber reinforced plastic sectional material. The guiding pultrusion mold comprises a main body, one end of the main body is provided with a fixing block, one end of the fixing block is provided with a mounting valve, and the fixing block is connected with a fixing frame of the main body through a plurality of support frames, the upper surface of the fixing frame is provided with a first mounting plate and a second mounting plate; the first mounting plate is provided with a first guide plate, and a first through hole is formed in the first guide plate; the second mounting plate is provided with a second guide plate, and a second through hole is formed in the second guide plate; the first guide plate and the second guide plate are arranged on a middle column, the middle column extends into a pultrusion system at the other end, and the contact part of the middle column and the pultrusion system is provided with a cross slot and a vertical slot, a plurality of electric heating holes are formed in the upper surface and the lower surface of the pultrusion system, and a pressing block is arranged in the pultrusion system. The guiding pultrusion mold disclosed by the invention has the following advantage of being reasonable in structure, the mold is uniformly heated, the transportation is convenient, the security coefficient is high and the cost is low, the working efficiency is high, and the mold is hard to damage.

Description

technical field [0001] The invention relates to a mold, in particular to an I-shaped glass fiber reinforced plastic section guide pultrusion mold. Background technique [0002] FRP is also known as glass fiber reinforced plastics, commonly known as FRP (Fiber Reinforced Plastics), that is, fiber reinforced composite plastics. According to the fiber used, it is divided into glass fiber reinforced composite plastic (GFRP), carbon fiber reinforced composite plastic (CFRP), boron fiber reinforced composite plastic, etc. [0003] It is a composite material with glass fiber and its products (glass cloth, tapes, felt, yarn, etc.) as reinforcing material and synthetic resin as a matrix material. Fiber-reinforced composites are composed of reinforcing fibers and a matrix. The diameter of the fiber (or whisker) is very small, generally below 10 μm, with fewer and smaller defects, and the fracture strain is about 30 / 1000. It is a brittle material that is easy to damage, break and cor...

AI Technical Summary

Problems solved by technology

[0008] The disadvantage of FRP is: low elastic modulus

Aging phenomenon is a common defect of plastics, and FRP is no exception. It is easy to cause performance degradation under the action of ultraviolet rays, wind, sand, rain, snow, chemical media, and mechanical stress.

low shear strength

The interlayer shear strength is borne by the resin, so it is very low
