Description
The IsoBeam is a rectangular, unidirectional, composite lattice structure designed for beam applications. Three carbon fiber specimens each 2 ft (0.61 m) long, 6 in. (152.4 mm) tall and 3 in. (76.2 mm) wide with four 6 in. (152.4 mm) bays were hand-woven and tested in bending. The beams each weighed between 1.82-1.86 lbs (8.09-8.27 N). A low maximum strength was achieved, primarily due to insufficient consolidation and inadequate manufacturing quality but the structure is seen to be very ductile and damage tolerant.
