Abstract
Fiber reinforced plastics (FRP) are one of the composite materials have high-strength, high-stiffness, and lightweight alternative to metals. Recently, advanced composite materials so as Iso Truss structures has been developed for alternative structures in the field of automotive and construction industry. In this report, we show the following acknowledgments of present study. The first, Iso Truss grid structures have been formed with carbon/epoxy FRP materials with helically filament-winding (FW) method. The next, influence of the tetrahedron region (pyramidal grid in this structure) on mechanical properties are measured. The third, for the applications of this structure the Christmas tree tower was constructed at campus of Kusiro N. C. T. with connected half a dozen pieces.
