Embodiment 1

[0023] The continuous glass fiber is impregnated with polypropylene (PP) to prepare a unidirectional continuous glass fiber reinforced PP prepreg tape, wherein the weight content of the glass fiber is 50%. Stack 32 layers of unidirectional prepreg tapes in an orthogonal manner, put them into a hot press machine with a length of 2.8 meters and a width of 1.5 meters, heat press at 185°C for 30 minutes, and then hold the pressure and cool and press to 2.3 meters Long, 1.2m wide laminated road reinforcement panels, 10.2mm thick.

Embodiment 2

[0025] The continuous Kevlar fiber is impregnated with polyethylene terephthalate (PET) to prepare a unidirectional continuous Kevlar fiber reinforced PET prepreg tape, wherein the weight content of the Kevlar fiber is 40%. Stack 25 layers of unidirectional prepreg tapes in an orthogonal manner, put them into a hot press machine with a length of 2 meters and a width of 1.5 meters, heat press at 280°C for 25 minutes, and then hold the pressure and cool down to form a 1.6-meter Long, 1.2m wide laminated road reinforcement panels, 8.1mm thick.

Embodiment 3

[0027] Use nylon 6 (PA6) to impregnate continuous stainless steel fibers to prepare a unidirectional continuous stainless steel fiber reinforced PA6 prepreg tape, wherein the weight content of stainless steel fibers is 80%. Stack 12 layers of unidirectional prepreg tapes in an orthogonal manner, put them into a hot press machine with a length of 2.0 meters and a width of 1.5 meters, heat press at 240 ° C for 15 minutes, and then hold the pressure and cool down to form a 1.6-meter Long, 1.2m wide laminated road reinforcement panels, 4.1mm thick.

Abstract

The invention relates to an application of thermoplastic resin composite materials in preparing a road reinforcing plate, which comprises the following steps: continuous fibres are placed in a soaking composite device to be soaked with the thermoplastic resin, so a unilateral continuous fibre reinforcement presoaking belt is obtained, wherein the weight percentage of the continuous fibre is 15%-85%; and a plurality of layers of unilateral continuous fibre reinforcement presoaking belts are laid on a hot-pressing machine of a plate, and under the melting temperature of the resin, a laminated road reinforcing plate is formed through hot-pressing for a certain time. Compared with the prior art, the invention is used as the road reinforcing plate for tanks and other engineering vehicles to run on deserts, marshes, mud basins and other soft grounds, the grounding pressure of the tanks is reduce, and the pass performance of the tanks and other engineering vehicles are favorably improved.

Description

technical field [0001] The invention relates to a road reinforcement board, in particular to the application of a thermoplastic resin composite material in the preparation of a road reinforcement board. Background technique [0002] When engineering vehicles such as tanks pass through soft ground such as deserts, swamps, and mud, due to their heavy weight, the tracks of engineering vehicles often sink into the soft ground and affect their traffic performance. Therefore, it is necessary to use road reinforcement plates to improve the traffic performance of engineering vehicles. Road reinforcement boards mainly include steel road reinforcement boards, thermosetting composite road reinforcement boards, etc. The steel road reinforcement plate has a good reinforcement effect, but it is too heavy, which is not conducive to transportation, handling, and laying, and affects the rapid operation of engineering vehicles. The thermosetting composite road reinforcement board is light i...
