Embodiment 1

[0013] A method for preparing a high-strength packaging composite material in this embodiment includes the following steps: using a high-strength, high-performance fiber reinforcement and a thermosetting resin matrix as raw materials, and adopting a vacuum infusion molding process to prepare a high-strength packaging composite material; The reinforcement is a high-strength and high-performance two-dimensional fabric reinforcement material. The resin matrix is ​​an epoxy resin matrix (model Snow Goose brand, Jiangsu Wujiang Heli Resin Factory). The high-strength and high-performance two-dimensional fabric reinforcement material adopts glass fiber plain weave cloth (purchased from Nanjing Fiberglass Research and Design Institute), and is cut into a size of 20cm × 20cm. Six layers are a unit. This embodiment uses Two units are superimposed; considering that special expensive instruments have high impact modulus requirements under unexpected conditions or during transportation, a ...

Abstract

The invention discloses a method for preparing a high-strength packaging composite, comprising the following steps: using high-strength high-performance fiber enhancement and thermosetting resin matrix as raw materials, and preparing the high-strength packaging composite by using a vacuum infusion forming technique; wherein the enhancement is one or two of high-strength high-performance two-dimensional fabric enhancing material and three-dimensional fabric enhancing material; the two-dimensional fabric enhancing material is two-dimensional fiberglass plain cloth; the three-dimensional enhancing material is in units of 3D six-layer quasi-orthogonal fabric made with high-strength fiberglass.It is guaranteed that the prepared packaging composite has different impact resistance and shows excellent performances such as high wear resistance and light weight; the packaging composite low in cost, light in weight, high in cost performance, high in strength and good in comprehensive performance is prepared, and the whole technical process is pollution-free and clean and is suitable for industrial large-scale production.

Description

technical field [0001] The invention relates to a preparation method of a high-strength packaging composite material, in particular to a preparation method of a high-strength packaging composite material with high-performance glass fiber as a reinforcing material and epoxy resin as a matrix. Background technique [0002] Fiber-reinforced resin-based composite materials have excellent properties such as high temperature resistance, corrosion resistance, and high strength, and are widely used in high-tech fields such as aerospace. The original packaging materials are generally wood and plastic, and fiber-reinforced resin-based composite materials are rarely used in the packaging industry. With the development of the packaging industry, the original packaging materials such as wood and plastic can no longer meet the packaging requirements of high-strength special instruments. Advanced high-performance fiber-reinforced composite materials have also begun to be gradually used in...
