It is the narrow web fabric or tubing formed using aramid fiber yarn as material knitting, there is high intensity, thickness has 0.4
~2mm, stretch modulus are 3 times of steel wire, and 2 times of glass, use temperature range is wide.With high temperature resistant, fire protection flame retarding, weight
The advantages that amount is light, high intensity, high-modulus, low-shrinkage, the good mechanical properties such as shellproof, shock resistance, dielectricity is good, it is anti-in individual
The fields such as shield, bullet resistant material have extensive use.To the impact in the bullet short time, high tenacity, high-energy absorption rate and high-elastic
The aramid fiber material of property modulus can absorb kinetic energy by rapid dispersion energy within the shortest time.
Increase the intensity that FRP armors 104 further improve optical cable, glass fiber reinforced composite plastic bar (FRP) has
The superior functions such as light weight, modulus height often substitute reinforcer 109 of the phosphating steel wire as optical cable in optic cable design, meet
Certain tensile strength, while there is anti-extraneous stress.When this gunshot-proof optical cable designs, shield is outer inside sets more circles
Shape FRP twists mode closing lay, to form one layer of armour protective layer using spiral.The further external force band such as buffering, dispersion bullet
The impact forces come, protect optical cable core not destroyed.
The effect and purpose of the present embodiment：
1), all dielectric provided in this embodiment makes somebody a mere figurehead gunshot-proof optical cable and provides new thought for the exploitation of optical cable.
2), all dielectric provided in this embodiment, which makes somebody a mere figurehead gunshot-proof optical cable, proves high intensity gunshot-proof optical cable, using light-duty complete
What dielectric structure can be achieved on.
3), all dielectric provided in this embodiment make somebody a mere figurehead gunshot-proof optical cable meet optical cable field make somebody a mere figurehead the stretching used, infiltration
Wait full performance tests requirement and 107 optical cable basic test performance of optical fiber.
4), all dielectric provided in this embodiment is maked somebody a mere figurehead gunshot-proof optical cable and is also provided for other high intensity type cable manufactures
Direction.
Embodiment 2.
The present embodiment provides a kind of all dielectric self-supporting gunshot-proof optical cable manufacture craft, as shown in figure 4, it includes following step
Suddenly：
Optical fiber 107 colours；
