Enhanced glass fiber reinforced plastic pultrusion profile and preparation method thereof

Abstract

The invention discloses a reinforced glass fiber reinforced plastic pultrusion profile and a preparation method thereof.The reinforced glass fiber reinforced plastic pultrusion profile comprises a first positioning frame, a supporting frame is fixedly arranged in the middle of the top of the first positioning frame, a second positioning frame is fixedly arranged at the top end of the supporting frame, and positioning plates are fixedly arranged at the two ends of the top of the second positioning frame; the two second positioning handles are pulled, so that the connecting plates drive the positioning buckles with the fixed bottom ends to be connected with the balance rod in a penetrating and inserting mode, the two to-be-spliced plates get close to each other, the two to-be-spliced plates are fixed through the connecting plates, the two to-be-spliced plates are fixed through the connecting plates, and the two to-be-spliced plates are fixed through the two to-be-spliced plates, so that the two to-be-spliced plates are fixed to the two to-be-spliced plates, and the two to-be-spliced plates are fixed. The two plates are moved to the two sides of the supporting frame, so that splicing of the plates is more stable, precise splicing of the plates is assisted, the plate splicing efficiency is improved, damage to the reinforced glass fiber reinforced plastic pultrusion profile is reduced, and the practicability of the reinforced glass fiber reinforced plastic pultrusion profile is improved.

Description

technical field [0001] The invention relates to the field of reinforced FRP pultrusion profiles, in particular to a reinforced FRP pultrusion profile and a preparation method thereof. Background technique [0002] There are many kinds of FRP pultruded profiles, FRP round tube, FRP square tube, FRP rectangular tube, FRP round rod, FRP I-beam, the basic components of pultruded FRP profiles are resin and glass fiber (including cloth, felt, etc.), it Fiber (including glass fiber, carbon fiber, organic fiber and other metal and non-metal fibers) is used as reinforcing material, resin (mainly epoxy resin, polyester resin, phenolic resin) is used as bonding agent, supplemented by other auxiliary materials (Main auxiliary materials: release agent, curing agent, catalyst, sealing agent, UV light stabilizer, mold cleaning water, gel coat, etc.) compounded. It has a series of excellent characteristics such as high temperature resistance, corrosion resistance, high strength, small spec...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, the I-shaped material in the FRP pultrusion profile is used when splicing two plates. The commonly used FRP pultrusion profile is easy to be damaged due to the connection and vibration of the plates, which not only makes the splicing between the plates difficult. tight, and it is easy to deform the body of the FRP pultruded profile, reducing the practicability of the FRP pultruded profile, so a reinforced FRP pultruded profile and its preparation method are needed
