The article shows prospects of composite materials application. We provide general con-
cepts and terms of composite materials, the technology of the assembly of highly respon-
sible and structural elements, drawbacks of the existing technology. An overview presents
advanced tools for the composite materials processing. When using these tools the stress
concentration around the drilled holes is reduced. The offered method of changing the
assembly technology is illustrated by the results of experiments.
It is shown that the pre-
preg obtained strength characteristics similar to those obtained on the uncured compo-
site material.
The results of the work can be used in rocket and space technology.
Key terms:
composite material, filler, matrix, binder, the prepreg, curing, drilling, punc-
turing.
