Abstract

The paper presents the results of a study of the technological characteristics of the formation of a composite material based on aluminum, reinforced with discrete boron fibers. Since boron has anomalously large neutron- absorption cross- section, the coating of a composite material with the addition of boron can be used as protection against thermal neutrons of gamma detectors of the outer surface of downhole geophysical devices. With the development of new technologies equipment decreases in size, the number of devices increases and free space in which protection system is placed becomes less. The use of this material allows manufacturing protective coating with a thickness of 1,5 mm and it provides much higher attenuation of the thermal neutron flux than currently used materials with a layer thickness of 5 mm. The results of test for thermocycling of composite material samples with different volume fraction of reinforcing agent (from 30 to 50 vol. %) are shown.
