Problems solved by technology

Since other preparation materials are crucial to its sound quality and volume, the existing thermoplastic materials are difficult to meet the needs of manufacturing guitars in terms of mechanical strength, specific strength, and flexibility.
Therefore, there is no plastic material guitar that is made of thermoplastic material and can be played directly without electricity.

preparation example Construction

[0036] The preparation method of this carbon fiber reinforced composite material includes:

[0037] Step S1: Mix acrylonitrile-butadiene-styrene copolymer, acrylonitrile-styrene copolymer and auxiliary agents in parts by weight to obtain a mixed material.

[0038] Among them, the additives are antioxidants and lubricants.

[0039] More specifically, a premixing agent is used for mixing, that is, acrylonitrile-butadiene-styrene copolymer, acrylonitrile-styrene copolymer and additives are added to the premixer in parts by weight, and mixed for 3 to 5 minutes to obtain Mix ingredients evenly.

[0040] Step S2: After mixing the mixed material with the carbon fiber, extruding and granulating.

[0041] Further, this step includes: kneading and melting the mixed material at 200-230°C, then mixing with carbon fibers, kneading and melting at 180-220°C, extruding and granulating, and cooling at 25-45°C .

[0042] Further, the carbon fiber reinforced composite material is prepared by...

Abstract

The invention provides a guitar, a guitar model body, and a preparation method for the guitar model body, and relates to the field of guitar preparation. The guitar model body comprises a back plate,a side plate and a neck of the guitar. The guitar model body is made of a carbon fiber composite reinforcing material, and is prepared in an integrated manner through the injection molding technology.The carbon fiber composite reinforcing material contains the following components by weight: 20 to 80 parts of acrylonitrile-butadiene-styrene copolymer, 15 to 35 parts of carbon fibers, and 5 to 30parts of acrylonitrile-styrene copolymer. The guitar model body can be bound with a panel and a sound beam to form an integrated guitar, thereby greatly improving the production efficiency of the guitar. The prepared guitar is better in sound quality, and the volume and acoustic performances of the prepared guitar are higher than the volume and acoustic performances of a wood guitar. Moreover, theguitar can be directly used for performance without power.

Description

technical field [0001] The invention relates to the field of guitar preparation, in particular to a guitar, a guitar shape and a preparation method thereof. Background technique [0002] At present, there are mainly two types of guitars on the market, wooden guitars and plastic material guitars. Among them, wooden guitars are usually prepared by manual processing of specific wood to obtain major components, such as back panels, panels, side panels, sound beams and necks, etc., and then use glue to manually bond the major components. The processing of this kind of wooden guitar requires nearly 200 processes, and the processing technology is cumbersome; and specific wood is required to meet the sound quality requirements of the guitar. For example, the most commonly used material for making panels is spruce, and the quality of the panels produced is different depending on the place of origin; The back and side panels need to be hard and strong, so commonly used woods include ...
