Embodiment 1

[0026] Such as figure 1 Shown, a kind of preparation method of fiber-reinforced composite mandrel comprises the following steps:

[0027] ① Pull the composite fiber 4 bundled with 10 strands of 1000tex thermoplastic resin fiber and glass fiber to the upper end of the oven 6 through the guide tube 5 .

[0028] ② Preheat the oven 6 to 160°C.

[0029] ③ Enter the composite fiber 4 into the oven 6 at a speed of 0.1m / min.

[0030] ④The thermoplastic resin fiber is melted and soaked into the glass fiber and enters the extrusion mold 7 at a speed of 0.1m / min. The composite fiber 4 is pultruded along the extrusion mold 7 under the action of its own gravity and traction to form a mandrel material 9 .

[0031] ⑤ Leading the extruded mandrel material 9 into the cooling water tank 3 for cooling.

[0032] ⑥ Pull the cooled mandrel material 9 into the measuring device 10 through the pulling device 8 for qualification inspection.

[0033] ⑦ Rewind the mandrel material 9 that has passed t...

Abstract

The invention discloses a preparation method of a fiber-reinforced composite mandrel. During production, thermoplastic resin fibers and glass fibers on a fiber support are bundled and then guided to the upper end of an oven through a bundle guiding tube; after the preheating temperature of the oven reaches the preset temperature, the thermoplastic resin fibers and the glass fibers are fed into the oven at the preset speed, and the process can be monitored and operated on an operating platform; when the thermoplastic resin fibers are molten and infiltrated into the glass fibers in the oven, the molten thermoplastic resin fibers are prevented from dropping under the action of a segmented automatic temperature control assembly, and a composite fiber enters a corresponding extruding mold after molten through a funnel-shaped channel; the composite fiber is pulled and extruded into a mandrel material through the extruding mold under actions of the gravity and the traction force of a traction device; the mandrel material enters a measurement device under the traction of the traction device for inspection after cooled through cooling water, is wound after inspected to be qualified, and is packaged after cut as per specifications.

Description

technical field [0001] The invention belongs to the field of optical cable reinforcing cores, and in particular relates to a preparation method of a fiber-reinforced composite core rod. Background technique [0002] At present, fiber-reinforced non-metallic reinforcing rods are widely used in the market, including basalt fiber-reinforced plastic rods and aramid fiber-reinforced plastic rods. Basalt fiber-reinforced plastic rods (BFRP) are inorganic fiber-reinforced composite materials, which have a large minimum bending radius, are easy to break and Problems such as poor combination with the cable sheath material limit its application in all-dielectric optical cables and home optical cables; although aramid fiber reinforced plastic rods (KFRP) have a relatively low bending radius, their materials are brittle in application , and the import price is high, and the localization of aramid fiber is low, the production penetration rate is low, and there are also problems such as p...
