Preparation method of epoxy resin glass fiber flute

Abstract

The invention discloses a preparation method of an epoxy resin glass fiber flute and belongs to the technical field of flute processing. The preparation method of the epoxy resin glass fiber flute comprises the following steps of: (1) weighing raw materials, and (2) conducting composite winding on the raw materials. The flute manufactured by the preparation method of the epoxy resin glass fiber flute is far lower than bamboo in temperature influence, shrinkage expansion coefficient and the like, the influence of the temperature on the flute (international standard pitch) is reduced to the minimum, the bamboo is replaced, the tone is excellent, the problems that the folk music wind instrument flute is cracked and the pitch of the original flute is influenced by the temperature are solved, the flute is hard, durable, not bent, poisonless and tasteless, the appearance and texture of the flute are beautiful, the bamboo wood is saved, and the national forest resources are protected. According to the preparation method of the epoxy resin glass fiber flute, the proportion is adjusted again, the problems of fluffing and wire drawing are solved, notches are flat and smooth, materials are not affected at all, the tone of the made flute is crisp, fine, smooth and soft and is very close to that of a flute made of bamboo, and the flute body also vibrates very well.

Description

technical field [0001] The invention belongs to the technical field of flute processing, and in particular relates to a method for preparing an epoxy resin glass fiber flute. Background technique [0002] At present, all folk music wind instruments flutes are made of bamboo. To make flutes, they are cut down from the mountains every year, causing certain damage to national forests, vegetation, environment, mountain forests, etc. Due to climate and temperature factors, flutes made of bamboo are prone to cracking. Due to temperature changes throughout the year, thermal expansion and contraction, folk music flute pairs (standard pitch) are not stable, etc., flutes made of bamboo have a limited lifespan, and generally last for a few years. To be replaced is a large amount of consumables, wasting forest resources! [0003] Epoxy resin fiberglass flute, the material is sustainable, does not damage the ecological environment, has the characteristics of pressure resistance, corrosi...

Problems solved by technology

[0004] The current technical difficulty is that the general epoxy resin glass fiber ratio is 70% glass fiber, but the edge of the flute incision and punching will be fuzzy, the glass fiber will be separated from the epoxy resin, and the epoxy resin prepared by the current method fiber weight
