Sheath Material

Polyamide 11 is a key material in the fabrication of offshore flexible pipes. It is mainly used as the flexible pressure layer assuring the impermeability of the fluid and gas carrying flexible pipe. A further important use is as outer sheath material where it protects efficiently the metal strip structure from sea water ingress even in highly dynamic applications. Given these important functions of polyamide 11 the knowledge of its precise material properties is essential for the design and the operating limits of flexible pipes. This paper aims to give a detailed understanding of the scope of the material properties such as fracture toughness, fatigue resistance and the mechanical response function. In a further step the influence of ageing on these properties is outlined with the aid of aged model specimen studies.

Sheath Material

Spheroids of the green colonial alga Volvox consist of biflagellate Chlamydomonad-like cells embedded in a transparent sheath. The sheath, important as a substance through which metabolic materials, light, and the sexual inducer must pass to and from the cells, has been shown to have an ordered structure (1,2). It is composed of both protein and carbohydrate (3); studies of V. rousseletii indicate an outside layer of sulfated polysaccharides (4).Ultrastructural studies of the sheath material in developmental stages of V. carteri f. weismannia were undertaken employing variations in the standard fixation procedure, ruthenium red, diaminobenzidine, and high voltage electron microscopy. Sheath formation begins after the completion of cell division and inversion of the daughter spheroids. Golgi, rough ER, and plasma membrane are actively involved in phases of sheath synthesis (Fig. 1). Six layers of ultrastructurally differentiated sheath material have been identified.
