Abstract: The present disclosure provides an arrow shaft with a high strength including, as the arrow shaft which has an arrowhead disposed at one side and an arrow nock disposed at the other side, at least one sheet layer which is laminated on and wound around at least a portion of an arrow shaft main body and is arranged in one direction, in which the sheet layer includes: a first sheet member which includes a plurality of sheet parts having at least some made of a transparent or translucent material and a second sheet member which has a strength reinforcing part formed on a portion where the first sheet member and at least a portion of the second sheet member overlap.

Abstract: An arrow shaft test apparatus, includes: a measuring machine body disposed lengthily in the left and right directions; a pair of arrow seating parts provided on the upper end of the measuring machine body, and disposed to be spaced at a predetermined distance apart from each other in the left and right directions; and a measuring sensor unit fixed to the measuring machine body, and for measuring the spacing distance forming with any outer circumferential surface of a shaft seated in the pair of arrow seating parts.

Abstract: Disclosed are a material for making a pole, a pole made of the material, and a tent including the pole. The material includes glass fiber or mineral fiber having unidirectionality in a circumferential direction of the pole. The glass fiber is GU glass fiber weaved and coated in one direction thereof. The glass fiber or the mineral fiber includes 30 wt % or more with respect to 100 wt % of the total weight.

Abstract: An arrow shaft includes a body having on opposite ends thereof an arrowhead and an arrow feather, and a pattern formed on an outer circumference of the body. The pattern is helically formed along the body, and the helical pattern is formed on a predetermined region in a direction from the arrowhead to the arrow feather.
