Abstract
A geologic core holder includes an elongated barrel constructed of a composite of wound and longitudinally extending nonmetallic fibers embedded in a resin matrix to provide a high strength structure which presents minimal attenuation of x-rays and magnetic flux. The barrel has opposed end flanges and the core holder includes removeable end plugs which are slideable in a bore formed by the barrel. Opposed pairs of split retaining blocks are engageable with the end flanges for securing the end plugs in the barrel bore. One of the end plugs is adapted to support a flexible sleeve for holding the core sample within a cavity formed in the barrel bore whereby fluid pressure may be applied to exert a particular pressure and temperature condition on the core so that pressure fluid flow characteristics through the core may be studied and x-ray imaged.
