Anti-ionizing radiation fiber-reinforced resin matrix composite and preparation method thereof

Abstract

In the invention, basalt fiber has relatively high content of heavy-nucleus elements such as iron and manganese, and the heavy-nucleus elements enhance the adsorbing and scattering effects of the basalt fiber on high-energy ionizing radiation; and compared with other reinforcing fiber, the basalt fiber has better ray shielding performance. The elements including tungsten and lead realize perfect weakening and shielding effects on the ionizing radiation with relatively high energy; and by adding the heavy metals tungsten and lead and other compound fillers, the energy of high-energy ray can be effectively reduced so that the high-energy ray is converted into low-energy radiation and further absorbed by the basalt fiber. In the invention, the heavy metals and compounds thereof, the resin matrix and the basalt fiber cooperate with each other and interact, and the obtained anti-ionizing radiation composite obtains good anti-radiation property and mechanical property.

Description

Technical field [0001] The invention relates to the technical field of functional composite materials, in particular to a fiber-reinforced resin-based composite material for preventing ionizing radiation and a preparation method thereof. Background technique [0002] Nuclear technique (nuclear technique) refers to modern high and new technology based on nuclear properties, nuclear reactions, nuclear effects and nuclear spectroscopy, with reactors, accelerators, radiation sources and nuclear radiation detectors as tools. It has high sensitivity, specificity, selectivity, anti-interference, penetrability and other characteristics. With the development of science and technology, nuclear technology has attracted more and more attention and has been widely used in various fields such as energy, medicine, national defense, agriculture, and aerospace. [0003] However, the biggest problem in the application of nuclear technology is ionizing radiation. Ionizing radiation is the general t...

Problems solved by technology

Although these materials have good radiation shielding properties, they often have obvious defects in mechanical properties. For example, the high density, toxicity and low mechanical properties of lead limit their applications. It is often necessary to increase the outer protective device and increase the system capacity. weight and cost; lead glass, lead-boron polyethylene, etc., which use lead or lead-containing compounds as functional fillers, have low mechanical properties and are difficult to meet the requirements of structural materials
