Conclusions
-
1.
The method of producing Al-B composite materials must ensure little or no formation of AlB2 at the matrix-filament interface.
-
2.
Use of a matrix of heat treated aluminum alloy and increasing the diameter of the boron filament makes it possible to double or triple the transverse strength of unidirectionally reinforced composites.
-
3.
The increase of the transverse strength due to crisscross reinforcement leads to reduction of the strength in the principal direction of the filament.
