Embodiment Construction

[0026] The present invention will be further elaborated below with specific embodiments.

[0027] The production process of this kind of composite material product comprises the following steps:

[0028] Step 1: Dip glass fiber cloth, kevlar cloth, carbon fiber cloth, bamboo veneer and other materials into thermosetting resin. Thermosetting resin is used to increase the strength of the cloth and to bond other layers.

[0029] Step 2: According to the requirements of the product, laminate the tape and other fabrics. The purpose of the tape is to increase the strength, and the fabric is the appearance of the product.

[0030] The third step: pass the laminated sheet through the mold to shape it, which is convenient to put into the soft rubber sleeve; put the shaped laminate into the soft rubber sleeve to complete the shaping of the product; put the shaped product into the sealed and pressure-resistant bag, so that the product is in a negative pressure state.

[0031] Step 4: P...

Abstract

The invention relates to a production technology of materials, in particular to a production technology of a composite material product. The production technology of the composite material product comprises the following steps that firstly, raw materials are made into rubber materials; secondly, the rubber materials are made into laminated materials; thirdly, the laminated materials are shaped through a mould, and are put into an outer sleeve, the outer sleeve is sleeved with a protection bag, and negative pressure is formed; fourthly, the product is put into a hot-pressing tank to be vulcanized, the pressure in the hot-pressing tank rises to 0.3 Mpa to 3.0 Mpa, the temperature of the hot-pressing tank rises to 60 DEG C to 300 DEG C, and after thermal forming is carried out for 15 minutes to 80 minutes, circulating cooling is carried out, and the product is taken out. According to the technology for producing the composite material product through the hot-pressing tank, the productivity and the efficiency are high, the yield is also high, and the size consistency of the product is good.

Description

technical field [0001] The invention relates to a material production process, in particular to a composite material product production process. Background technique [0002] Composite products such as bamboo veneer, carbon fiber, and kevlar currently on the market are generally formed by a hot press, with a pressure of 0.6Mpa-20Mpa and a temperature of 85°C-300°C. The resin used is thermosetting or thermoplastic. resin. Using thermosetting resin-impregnated glass fiber cloth, kevlar cloth, carbon fiber cloth, bamboo veneer and other materials, the product is formed by lamination, molding and heating, and then the modeling process is completed by laser cutting and CNC engraving, and finally it is made by spraying and printing. finished product". There are no companies that use the autoclave process to produce composite products. Generally, autoclave is used to produce tires and shoe soles in the market. [0003] This production process in the current market has the follow...
