FIELD: process engineering.
SUBSTANCE: invention relates to fabrication of ultra-light aircraft rubs from fibrous composites. Shaped truss structure comprises top and bottom lines with connection props with reinforcement at connection zone. Fibrous material impregnated with binder is laid in grooves of rigging, said material being forced through every structural element of truss structure for preset number of times. Then produced truss structure is solidified and removed from rigging. Note here that fibrous material impregnated with binder is laid in said grooves in paths that rule out acute angles at transition of fibrous material from line to prop and vice versa.
EFFECT: lower labour input, decreased weight.
