Fig. 1 is structural representation of the present invention.
Fig. 2 is that inventive samples test result gathers chart.
Embodiment
Below in conjunction with concrete embodiment, patent of the present invention is described further, but not as the restriction to patent of the present invention.
A kind of automobile line protective casing of an embodiment of patent of the present invention; the cylindrical sleeve of the both ends open be made up of pipe and aramid fiber outer tube in glass, is characterized in that having following three technical processs: interior pipe forming process, outer tube forming process, bonding process.
Interior pipe forming process: glass fibre is carried out 3 D weaving, makes it form the tubular sleeve of both ends open, and glass fibre adopts 3 D weaving, makes it have anisotropy, enhances the shock resistance of all directions of sleeve pipe.
Knitting process: weave respectively glass fibre, aramid fiber, makes the tubing string of two tubulars.Wherein glass fibre adopts 3 D weaving, makes it have anisotropy, enhances the shock resistance of all directions of sleeve pipe.
Outer tube forming process: first aramid fiber is carried out boundling process, latitude plain stitch is carried out in the aramid fiber pipe outside in glass after secondly using process, and one step forming is outer tube.Boundling process uses polyurethane resin to carry out starching to aramid fiber to aramid fiber, its intensity improved, has boundling, on-run effect.Aramid fiber adopts latitude plain stitch, improves dimensional stability and the morphological stability of sleeve pipe simultaneously.
Bonding process: the internal and external casing be shaped is passed through resin bonding, then carries out hot setting process, make it be shaped.Bonding process comprises soaking paste, scrapes the treatment process such as slurry, hot setting.Soaking paste makes sleeve pipe with certain speed by resin stock tank; Scraping slurry can make slurries soak into space between sleeve pipe; In two steps, initial temperature is 120 DEG C or 115 DEG C or 125 DEG C to hot setting, solidifies 10 minutes or 8 minutes or 12 minutes, and following temperature is 170 DEG C or 175 DEG C or 165 DEG C, solidifies 20 minutes or 18 minutes or 22 minutes.
