Embodiment Construction

[0025] A carbon fiber product, please refer to figure 2 , it is the tripod 30 of carbon fiber bicycle, and this tripod 30 is tubular. For the mold used in this carbon fiber product, please refer to image 3 , which includes a mold core 10 and an outer mold, the mold can refer to a traditional mold.

[0026] A carbon fiber product molding method, it comprises the following steps:

[0027] Step 1, the inner core body processing step, using Baolilong to process the inner core body 20 suitable for the shape of the carbon fiber product 30, in this embodiment, the shape of the inner core body 20 matches the shape of the inner cavity of the tripod 30;

[0028] Step 2, the air bag wrapping step, wraps the air bag 40 outside the inner core, and the inner core 20 is fixed with an air intake nozzle 50 and an exhaust nozzle 60, wherein the air intake nozzle 50 and the exhaust nozzle 60 are both Connect the air bag 40;

[0029] Step 3, carbon fiber wrapping step, wrapping multiple lay...

Abstract

The invention discloses a method for molding a carbon fiber product, which comprises: a step 1 of processing an inner core body, in which a core body adaptive to the shape of the carbon fiber product is processed by adopting a foam material with the characteristic of thermal contraction; a step 2 of wrapping with an air bag, in which the outside of the core body is wrapped with an air bag, and an air inlet nozzle which is connected with the air bag is arranged; a step 3 of wrapping with a plurality of carbon fiber layers, in which the outside of the air bag is wrapped with a plurality of carbon fiber layers, and then the air bag is put into a die; a step 4 of heating curing, in which steam or hot air is led into the air bag through the air inlet nozzle for heating, the heating ensures that the inner core body shrinks, the shrinking ensures that a gap is formed between the air bag and the inner core body, the gap forms a conveying air duct, and the steam or the hot wind flows in the conveying air duct and heats the plurality of the carbon fiber layers so as to fuse the carbon fiber layers and solidify the product; a step 5 of cooling with water, in which the air inlet nozzle and an air outlet nozzle are adopted; and a step 6 of taking out the core body, in which the die is opened for taking out the inner core body. The technical proposal of the method has the advantages of less heating consumption, high molding efficiency and cost reduction.

Description

technical field [0001] The invention relates to a method for forming a carbon fiber product, in particular to a method for forming a carbon fiber product by using hot steam. Background technique [0002] Traditional carbon fiber product 30 molding method, the device that this method adopts is as figure 1 As shown, it includes a mold 20 and a template 10 that holds the mold 20 . The method includes the following steps: Step 1, assembling multiple carbon fiber layers in the mold; Step 2, closing the mold; Step 3, heating the template 10 to cure the product: the template 10 transfers heat to the mold 20, and the mold 20 The heat is transferred to the multi-layer carbon fiber layers to fuse the multi-layer carbon fiber layers, so that the fusion is solidified and formed into a carbon fiber product 30 . Step 4, cooling step: cooling the mold 20 with cold water. Firstly, the external heat is used to fuse the carbon fiber layer after multiple transfers, resulting in large heat l...
