specific Embodiment approach 1

[0026] Specific embodiment one: the preparation method of the composite transmission tube blank formed by fiber winding, which is completed by the following steps:

[0027] Step 1. Preheating the mold to 40°C to 50°C;

[0028] Step 2: Coating the preheated mold, the entire coating is evenly distributed on the surface of the mold, and the thickness of the coating is 5um to 10um;

[0029] Step 3. Install the mold processed in step 2 on the winding machine, and then heat the mold to 80℃~100℃;

[0030] Step 4. Install the glass fiber on the fiber tensioner, and set the tension at 0.5kg-5kg;

[0031] Step 5. Pull the glass fiber through the mixed glue in the glue tank to the mold, remove the dry yarn, import it into the mold and start winding, set the winding thickness to 0.05mm~1mm, and stop winding after reaching the set thickness;

[0032] Step 6. Install the carbon fiber on the fiber tensioner, set the tension to 0.5kg~5kg; set the winding parameters, and the winding angles a...

specific Embodiment approach 2

[0039] Specific embodiment 2: The difference between this embodiment and specific embodiment 1 is that the mixed glue solution is obtained by the following method: epoxy resin, curing agent, diluent, and additives are mixed in a weight ratio of 100:4:10: The mixed glue solution was prepared in a ratio of 10, and the mixed glue solution was obtained after stirring for 20 minutes with an electronic mixer. Other compositions and connection methods are the same as those in Embodiment 1.

specific Embodiment approach 3

[0040] Specific embodiment three: the preparation method of the composite material transmission tube blank formed by fiber winding as described in specific embodiment one, step six, install the aramid fiber on the fiber tensioner, set the tension to 0.5kg-5kg; set Set the winding parameters, the winding angles are respectively 15°, 30°, 60°, 30° and 15° alternately, and each winding angle corresponds to the thickness of the single layer being wound as 0.5mm, 0.7mm, 1mm, 0.7mm and 0.5mm, traversing all winding angles constitutes a winding cycle. Other steps are the same as in the first embodiment.

Abstract

The invention discloses a method for preparing a transmission tube blank made from a filament wound composite material, and relates to a method for preparing a transmission tube blank. The invention aims to solve the problem that a dynamic load transmission tube blank made of a metal material is easily resonated with other metal parts to threaten the safety of an aircraft, and has low humidity resistance and moldproof property. The method comprises the following steps of: 1, preheating a mold; 2, covering a film on the mold; 3, heating the mold; 4, arranging glass fibers on a fiber tensioner; 5, dragging the glass fibers into the mold; 6, arranging carbon fibers on the fiber tensioner; 7, winding a main structural layer; 8, winding the glass fibers; 9, regulating winding parameters and winding again; 10, curing and molding; 11, demolding; and 12, performing surface treatment. The composite material wound transmission tube blank has the advantages of high humidity resistance and high moldproof property, avoids resonance with other metal parts, and greatly improves the safety of the aircraft.

Description

technical field [0001] The invention relates to a preparation method of a transmission tube blank. Background technique [0002] With the rapid development of material technology, composite materials are widely used because of their high specific strength, high specific stiffness, excellent vibration damping, fatigue resistance, and corrosion resistance compared with metal materials; The dynamic load transmission tube blank has always been processed by metal materials, and the metal transmission tube blank is very easy to resonate with other metal parts, causing damage to the transmission tube blank or metal parts, which greatly threatens the flight safety of the aircraft, and the metal material The traditional transmission tube blank also has the problems of poor moisture resistance and poor mold resistance. Contents of the invention [0003] In order to solve the problem that the dynamic load transmission tube blank of the existing metal material is easy to resonate wit...
