Embodiment 1

[0050] The autoclave process refers to the process of laying up the single-layer prepreg in a predetermined direction to form a composite material blank, placing it in an autoclave, and completing the curing process under a certain temperature and pressure. An autoclave is a special pressure vessel that can withstand and regulate a set temperature and pressure range. The blank is laid on the surface of the mold with a release agent, and then covered with a porous anti-adhesive cloth (membrane), suction felt and air felt, sealed in a vacuum bag, and then put into an autoclave. Before heating and curing, vacuumize the bag to remove air and volatiles, and then heat up, pressurize and cure according to the curing system of different resins.

[0051] The formulation and implementation of curing system is the key to ensure the quality of autoclave molded parts. After heating to a certain temperature, pressurize the billet. The pressure should be to ensure the compaction of the work...

Embodiment 2

[0080] Such as Figure 8 and Figure 9 As shown, on the basis of embodiment 1, this embodiment provides a propeller composite material conduit, which is made by the method described in embodiment 1.

[0081] Preferably, as Figure 8 with Figure 9 As shown, in one of the preferred technical solutions of the present application, the structure of the propeller composite conduit includes: a support frame 7 and a skin 8; the shape of the skin 8 is ring-shaped; the support frame includes: a hub body 1 and the blade 2; the two ends of the blade 2 are fixedly connected to the outer wall of the hub body 1 and the inner wall of the skin 8 respectively.

[0082] Preferably, as Figure 8 with Figure 9 As shown, in one of the preferred technical solutions of the present application, the skin 8 includes an outer skin 6 and an inner skin 3; ribs 4 are arranged inside the skin; one end of the blade 2 and the ribs 4 fixed connection.

[0083] Preferably, in one of the preferred techni...

Abstract

The object of the present invention is to provide a kind of propellor composite material conduit and its preparation method, relate to new material and new process; comprise the following steps: adopt carbon fiber / epoxy resin prepreg cloth as raw material, make hub body according to autoclave process, Blades and ribs; making support frames; processing and forming the inner skin by using autoclave technology, opening slotted holes on the annular inner wall of the inner skin; processing and setting bolt holes and / or fixed ends of mortise and tenon joints on the ribs; The connecting end of the blade passes through the slot hole and is bonded to the inner skin; the rib plate is fixedly connected to the connecting end; the rib plate is bonded to the inner surface of the inner skin; The buoyancy materials are filled in the multiple intervals of each space, and the exposed parts are trimmed out of the outer surface, and the carbon fiber / epoxy resin prepreg cloth is spread on the outer surface, and the outer skin is formed by the autoclave process, and after trimming Obtain the finished product. The invention can reduce the weight of the existing propeller guide tube and has better seawater corrosion resistance.

Description

technical field [0001] The invention relates to the technical field of composite catheters, in particular to a propeller composite catheter and a preparation method thereof. Background technique [0002] In the prior art, the propeller conduits of deep-sea manned submersibles are usually made of metal materials, which have the technical problems of heavy weight and poor seawater corrosion resistance. Carbon fiber reinforced resin matrix composites have the characteristics of low density, corrosion resistance, high specific strength and specific modulus, and designability, and are excellent structural materials. Compared with metal materials, carbon fiber reinforced resin-based composite materials can greatly reduce the weight of its body on the one hand, and on the other hand, it can also improve its corrosion resistance to seawater and prolong the service life of deep-sea manned submersibles. The carbon fiber reinforced resin-based composite materials obtained according to...
