specific Embodiment approach 1

[0012] Specific Embodiment 1: The preparation method of basalt fiber cloth filled ultra-high-speed impact protection structural material in this embodiment is realized according to the following steps: 1. Spray glue on basalt fiber cloth, and then dry it; 2. Arrange the dried basalt fiber in Whipple In the protective structure, the basalt fiber cloth is obtained to fill the ultra-high-speed impact protective structure material; in the first step, the type of glue sprayed is neoprene, epoxy resin glue or liquid sodium silicate.

[0013] In the first step of this embodiment, glue spraying treatment is to spray a layer of glue on the basalt fiber cloth.

[0014] The type of glue sprayed in step 1 of this embodiment adopts neoprene or liquid sodium silicate, both of which are finished glue sold on the market; epoxy resin glue needs to be prepared on site, using 618# epoxy resin, adding 8% of the mass of epoxy resin % to 10% of curing agent and 20% to 30% of epoxy resin mass plasti...

specific Embodiment approach 2

[0022] Embodiment 2: This embodiment differs from Embodiment 1 in that the basalt fiber cloth in step 1 is a two-dimensional or three-dimensional fabric woven from basalt fiber yarns. Other steps and parameters are the same as those in Embodiment 1.

specific Embodiment approach 3

[0023] Specific Embodiment Three: This Embodiment The preparation method of the basalt fiber cloth filled ultra-high-speed impact protection structural material in this embodiment is realized according to the following steps: 1. The basalt fiber cloth is sprayed with glue, and then dried; 2. The dried basalt fiber Arranged in the Whipple protective structure, the basalt fiber cloth filled ultra-high-speed impact protective structural material is obtained; the glue used in the first step is epoxy resin glue.

[0024] The basalt fiber cloth obtained in this embodiment is filled with ultra-high-speed impact protection structural materials such as figure 1 As shown, it is composed of aluminum protective screen, aluminum bulkhead plate, thin aluminum plate and basalt fiber cloth, in which the aluminum protective screen 1 is an aluminum alloy plate of 1-2 mm, and the aluminum bulkhead plate 2 is an aluminum alloy plate of 3-5 mm. The aluminum plate 3 is an aluminum alloy plate of 0....

Abstract

The invention provides a method for preparing a basalt fiber cloth-filled ultra high-speed impact protective structure material and relates to the method for preparing an impact protective structure material. The method solves the problems of difficultly obtained materials such as Kevlar and Nextel used in the conventional N / K-filled Whipple protective structure and high cost, and poor impact and damage resisting protective performance of the materials related in a thesis 'Damage Analysis for Basalt Fiber Cloth Whipple Protective Structure Ultra High-speed Impact'. The method comprises the following steps of: 1, spraying glue on basalt fiber cloth, and then drying the basalt fiber cloth; and 2, placing the dried basalt fiber cloth into a Whipple protective structure to obtain the material. The basalt fiber cloth is easy to obtain and has low cost which is only 35 yuan / kg, and good impact and damage resisting protective effect after the basalt fiber cloth-filled ultra high-speed impact protective structure material is prepared by using the basalt fiber cloth; and compared with the N / K filling Whipple protective structure, the basalt fiber cloth-filled ultra high-speed impact protective structure material has equal or better performance.

Description

technical field [0001] The invention relates to a preparation method of an impact protection structural material. Background technique [0002] At present, the protective structure widely used in the ultra-high-speed collision protection project of spacecraft space debris is to set a protective barrier outside the main bulkhead structure of the spacecraft, which is called a protective screen or a protective plate. When space debris hits the spacecraft, it first collides with the protective screen, the space debris is broken into smaller secondary debris, and its physical state also changes, such as melting or vaporization, which forms a "secondary debris cloud" . When the secondary debris cloud finally hits the main bulkhead structure of the spacecraft, it has been transformed into multi-point impacts scattered over a large impact area, which reduces the damage of space debris to the main bulkhead structure of the spacecraft. This protection concept was proposed by America...
