In the three-dimensional woven fabric laminate 13 of the tubular article 10b with flanges at both ends, the individual three-dimensional woven fabrics 1 alternately form the tubular portions 2 alternately with the tubular portions 2 of the other three-dimensional woven fabrics 1 from the front end side, as in the example of FIG. After inserting the tubular portion 2 into the tubular portion 2 of another three-dimensional fabric 1, the warp yarn extension portion 14 at the tip of the tubular portion 2 is inserted.
Is spread radially and is made to follow the disk-shaped portion 3 of the three-dimensional fabric 1 on the ground.
作用及び発明の効果 本発明によれば、複合材製のフランジ付き管状物品10
の強化材を構成する立体織物１が、その管状部２と円盤
状部３とが連続した一体の織物構造により構成されてい
るので、強化材が管状部とフランジ部とで組織がとぎれ
ることがなく、一体に連続したものとなる。According to the present invention, a flanged tubular article 10 made of a composite material is provided.
Since the three-dimensional woven fabric 1 constituting the reinforcing material is constituted by an integrated woven structure in which the tubular portion 2 and the disc-shaped portion 3 are continuous, the structure of the reinforcing material may be cut off between the tubular portion and the flange portion. Instead, they are continuously continuous.
従ってフランジ付き管状物品10においても、その管状
部11とフランジ部12とがそれぞれ強化されているだけで
なく、その連結部においても強化され、他の部分と同等
の強度を有しており、大きな力が加わったようなときに
も管状部11とフランジ部12との連結部から破損するよう
なことがない。Therefore, also in the flanged tubular article 10, the tubular portion 11 and the flange portion 12 are not only reinforced, but also reinforced at the connection portion, and have the same strength as other portions, Even when a force is applied, the connection between the tubular portion 11 and the flange portion 12 is not damaged.
しかも立体織物１の円盤状部３は管状部２と連続した
織物構造を有しているので、周方向にも充分に強化され
ており、たて糸４のみを放射状に配置した場合のように
放射状のひび割れが生じるようなこともない。In addition, since the disk-shaped portion 3 of the three-dimensional fabric 1 has a woven structure continuous with the tubular portion 2, it is sufficiently reinforced in the circumferential direction, and has a radial shape as in the case where only the warp yarns 4 are radially arranged. No cracking occurs.
