| Abstract: | The effective deformative characteristics of spatially reinforced composites made by spatial braiding along the generatrices
of a one-sheet hyperboloid are analyzed. The geometrical relationships determining the structure of a unit cell of a braided
composite are derived. The effective thermoelastic characteristics are calculated by the method of orientational averaging.
The dependences of the bending and torsional stiffnesses of thick-walled cylindrical rods — made by the method suggested and
by winding — on the braiding/winding angle are compared. The numerical estimations are given for rods made of carbon (CFRP)
and aramid (AFRP) epoxy plastics.
