Carbon frame and manufacturing method therefor

Abstract

The present invention relates to a carbon frame and a manufacturing method therefor, and provided are a carbon frame manufacturing method capable of improving torsional stiffness, and a carbon frame manufactured thereby, the method comprising the steps of: (a) preparing at least two pieces of foam; (b) wrapping up each piece of foam with plastic; (c) stacking a carbon prepreg on the plastic; (d) combining the piece of foam so as to put same in a mold; and (e) injecting heat and wind into the plastic.

Description

technical field [0001] The present invention relates to a carbon frame and a manufacturing method thereof, and more particularly, to a carbon frame capable of improving torsional rigidity and a manufacturing method thereof. Background technique [0002] In general, a frame is a structural member for maintaining the shape of machines, appliances, and devices, and is formed of various materials such as wood, metal, plastic, and the like. In particular, recently, frames of carbon materials that are light in weight and excellent in strength have been developed and applied to various fields. [0003] For example, in the case of bicycles, weight reduction is evaluated as an important factor for ease of movement, transportation, and storage, so carbon frames have been used so far. However, because carbon frames are expensive, carbon frames are usually only partly used in expensive lineups or in the main frames that carry the heaviest loads. [0004] The main frame receives loads ...

AI Technical Summary

Problems solved by technology

However, due to the flexible nature of carbon frames, the torsional loads applied when pedaling can become more of an issue

[0005] For this reason, there are constant attempts to increase the torsional rigidity of the carbon frame, but no solution has yet been found
