2k type boron fiber is operable at temperatures up to 300[degrees]C [1-8].
One of the most promising CM in the field of aircraft and rocket construction are boron fiber, made with the use of reinforcing boron fiber and epoxy matrices .
Thus, aluminum alloys reinforced with boron fibers can be reliably operated at temperatures up to (450-500)[degrees]C instead of (250-300)[degrees]C [1-5].
In this CM with a matrix of aluminum alloys, boron fibers (sometimes coated with silicon carbide SiC) are used as the reinforcing filler .
This version has many revisions, new section numbers and headings, some reorganization, new sections on boron fiber
composites, and new information on glass fiber composites, and it deletes other information.
These materials were typically 40% graphite, 20% boron fiber, and 40% epoxy.
Until then, the only available reinforcement was glass, although boron fibers were also coming on the scene.
For example, in an aluminum-boron composite, the tool encounters a soft aluminum matrix and hard boron fibers
The boron fibers
come from Specialty Materials in the U.
