At the deficiency that prior art exists, technical problem to be solved in the utility model is to provide a kind of composite material sleeper, the intensity height, long service life, corrosion-resistant, good insulation preformance, weatherability is strong, endurance, good springiness has solved vibration effect and noise pollution that orbital region produces.
For solving the problems of the technologies described above, the technical scheme that the utility model is taked is, a kind of composite material sleeper, and described sleeper is for being the hollow housing of reinforcing material to cloth with continuous glass fibre and glass fiber multiaxis; Described sleeper cross section is horizontal round rectangle; The hollow channel that it is vertical round rectangle that described sleeper vertically is provided with three cross sections.
Optimize, above-mentioned composite material sleeper, the radius of corner of the cross section of its sleeper and three hollow channels is 10mm.
Optimize, above-mentioned composite material sleeper, the length of the cross section of its sleeper is 240mm, width is 150mm.
Optimize, above-mentioned composite material sleeper, its hollow channel comprise that two symmetries are positioned at the passage and the passage that is positioned at the sleeper middle part of sleeper both sides; The distance that is positioned at the sidewall of the passage of sleeper both sides and sleeper is 10mm.
Optimize, above-mentioned composite material sleeper, its passage that is positioned at the sleeper middle part is 15mm with the spacing that is positioned at the passage of sleeper both sides.
Optimize, the spacing at two ends is 18-22mm about the above-mentioned composite material sleeper, its passage that is positioned at the sleeper middle part and sleeper.
The utility model composite material sleeper has more following characteristics: corrosion resistance, and not perishable under the natural environment, can guarantee the good precision of the long-term maintenance of track; Weather resisteant, cracking does not take place after handling in external coating under natural environment, still do not influence its performance at high temperature under the low temperature environment for use; Fatigue durability, because of good corrosion resistance and weather resisteant height, the endurance life-span is also long; Anti-electrical insulating property, the insulaion resistance height does not have Insulation Problems; Processability can be cut according to Len req; Elasticity---better elastic has reduced railway roadbed rigidity, plays the effect of favorable damping noise reduction; The property produced in batches can be produced and long line production as industrial product is a large amount of.
