    • This invention is concerned with means for detecting potential fracturing, such as stress fractures, or damage to, a fibre based structure, by incorporating either hollow fibres containing coloured fluids, or solid fibres, or hollow fibres containing coloured fluids or fluids, which are capable of changing their visual appearance when exposed to external forces, and/or by incorporating fibres within the structure which can change a property such as electrical resistance, capacitance or inductance so that there is an indication whenever and wherever and the extent when a fracture occurs. Where coloured fluids are used, detection is by leakage of the fluid around the fracture. Where colour changing fluids are employed, detection is by observation of change of colour of the fluid. Different fluids can be used for different levels in the strata of tubes in the structure and where these are embedded within the structure, they can be observed where the fibres emanate from the body of the structure. Where fibres are incorporated into the structure that rely on electrical properties to sense a fracture, these fibres may be solid and formed from electrically conductive material and may be coated with such material. Alternatively, though used together with solid fibres, hollow fibres may be used where those hollow fibres contain and/or are coated with electrically conductive material. Appropriate detector means are associated with these fibres to detect the occurrence of a fracture.
    • 本发明涉及通过掺入含有着色流体的中空纤维或含有有色液体或固体纤维的中空纤维来检测潜在的压裂,例如应力断裂或损坏纤维基结构的方法 在暴露于外力时改变其视觉外观,和/或通过在结构内结合纤维,其可以改变诸如电阻,电容或电感的性质,使得当断裂发生时每当和任何地方和程度都有指示。 在使用彩色液体的情况下,检测是通过裂缝周围的流体泄漏。 在使用变色流体的情况下,通过观察流体颜色的变化来进行检测。 不同的流体可以用于结构中的管的层中的不同水平,并且其中嵌入结构中的那些,可以观察到纤维从结构体发出的位置。 当纤维结合到依赖于电性能以感测断裂的结构中时,这些纤维可以是固体的并且由导电材料形成并且可以用这种材料涂覆。 或者,尽管与固体纤维一起使用,但是当中空纤维含有和/或涂覆有导电材料时,可以使用中空纤维。 合适的检测器装置与这些纤维相关联以检测骨折的发生。

    • A filled hollow fibre composite material is made by laying up a plurality of prepreg plies (1) of hollow fibre composite material and non-stick film material (2) one on top of another with the non-stick film material (2) interleaving successive plies (1) at selected areas thereof. The laid up interleaved plies are treated to resin bond the ply areas (3) not interleaved with the non-stick film material and leave the interleaved areas (4) unbonded. The so formed laminate is treated at edge regions to expose open unfilled hollow fibre ends (5, 6) and the plies in the unbonded interleaved areas (4) are separated at the non-stick film material (2) to provide access to the open hollow fibre ends (7) in each ply for the introduction of a film material into the hollow fibres through the open hollow fibre ends (7) in one or more of the separated plies (1) to form a filled hollow fibre composite material.
    • 填充中空纤维复合材料通过将不粘膜材料(2)交替连续地铺设多个中空纤维复合材料和不粘膜材料(2)的预浸料层(1)而形成, (1)在其选定区域。 将铺设的交织层处理成树脂粘合不与不粘膜材料交织的层区域(3),并使交错区域(4)未粘合。 在边缘区域处理如此形成的层压体以暴露开放的未填充中空纤维端部(5,6),并且未粘合交织区域(4)中的层在不粘膜材料(2)处分离以提供通向开口 每个层中的中空纤维端部(7),用于通过一个或多个分离层(1)中的开口中空纤维端部(7)将膜材料引入中空纤维中,以形成填充的中空纤维复合材料。
