Abstract
An X-ray transmission member including a substantially sheet-like X-ray transmitting part composed of a fiber-reinforced plastic containing discontinuous reinforcing fibers and a resin, the X-ray transmitting part having uneven thickness and a substantially uniform area weight. Provided is an X-ray transmission member made of a fiber-reinforced plastic, the member having a uniform radiolucency even if it has a shape whose thickness varies in the member plane.
Claims15
An X-ray transmission member comprising a substantially sheet-like X-ray transmitting part composed of a fiber-reinforced plastic containing discontinuous reinforcing fibers and a resin, the X-ray transmitting part having uneven thickness and a substantially uniform area weight,
- wherein the coefficient of variation (CV) value of the area weight in the whole area of the X-ray transmitting part is not more than 5%,
- wherein the CV value of the rate of radiolucency in the whole area of the X-ray transmitting part is not more than 5%,
- wherein the fiber-reinforced plastic is a porous body in which voids are formed, and
- wherein the X-ray transmission member further comprises a skin layer.
