To provide a pipe renovation material that has properties to easily produce pipes and drill holes, and that can secure required strength.SOLUTION: There is provided a pipe renovation material 10, in which a length direction and a width direction of a renovation member 11 composed of synthetic resin are arranged along the peripheral surface in a renovation pipe 3. A planar reinforcing material 20 is provided in a plane along the length direction and the width direction of the renovation member 11. A fibrous body 30 is fixed to a base material 21 composed of synthetic resin in the planar reinforcing material 20. A warp fiber material 31 of the fibrous body 30 is oriented in the length direction, and a weft fiber material 32 is oriented in the width direction.SELECTED DRAWING: Figure 2 【課題】製管や削孔が容易であり、所要の強度確保などが可能な管更生材を提供する。【解決手段】管更生材１０の合成樹脂からなる更生部材１１の長さ方向及び幅方向を更生管３の周面に沿わせる。更生部材１１の長さ方向及び幅方向に沿う面内に面状補強材２０を設ける。面状補強材２０の合成樹脂からなる母材２１に繊維体３０を固定する。繊維体３０の経繊維材３１を長さ方向に配向させ、緯繊維材３２を幅方向に配向させる。【選択図】図２
