    Abstract: PROBLEM TO BE SOLVED: To provide a member for a piping system for a fuel cell, wherein intercepting action with respect to hydrocarbons, alcohols and hydrogen is improved, and each layer firmly adheres mutually.
    SOLUTION: In the member for the piping system for the fuel cell, an innermost layer I, in contact with a conveyed medium, is made of a polyolefine compound. The material is bound to a layer II made of an EVOH compound. Here, the combination may also have a layer selected from (a) a layer III made of a polyamide compound, (b) a layer IV made of a molding material comprising functionalized polyolefine, and (c) a layer V comprising an unfunctionalized polyolefine molding material. The layer I and the layers II are coupled by having a contact surface of the layer I contain the polyolefine having a functional group selected from among an acid anhydride group, a carboxylic acid group, an N-acyl lactam group, an epoxy group and a trialkoxysilane group.

    Abstract: PROBLEM TO BE SOLVED: To provide a multilayer composite material having a good cut-off effect against a medium brought into contact with the material while an adhesive force between layers after cooling liquid is operated for a long time as it is after storage for a long time in a methanol-containing fuel at a high temperature or under operating conditions with rigidity without additional adherence auxiliary layer at all. SOLUTION: In the multilayer composite material comprising a layer I made of at least polyamide molding material and a layer II made of a polyester molding material, the polyester molding material contains a mixture of (a) 80 to 99 wt.% of polyalkylene-2, 6-naphthalate selected from polyethylene-2,6- naphthalate and polybutylene-2,6-naphthalate, and (b) 1 to 20 wt.% of one or more types of compound having at least two isocyanate groups.

    Abstract: PROBLEM TO BE SOLVED: To provide a liquid- or vapor-conducting system with a jointing zone comprising a coextruded multilayer composite. SOLUTION: The liquid- or vapor-conducting system comprises the following elements: I. a jointing element; II. the jointing zone made of a coextruded multilayer composite comprising at least two layers; and III. a hollow article, with the elements I, II and III material bonded to one another. Permanent firm bonding between a connecting member and the hollow article is achieved, along with a reduction in emissions contaminating the environment. COPYRIGHT: (C)2003,JPO

    Abstract: PROBLEM TO BE SOLVED: To provide a multilayer composite material of a polyamide base of which all the layers have sufficient heat distortion temperatures. SOLUTION: The multilayer composite material has a layer I constituted of a molding material which contains constituents: (a) a polyamide of 0-80 pts.mass selected from PA6, PA66 and PA6/66, (b) a polyamine-polyamide copolymer of 0-100 pts.mass, and (c) polyamide of 0-80 pts.mass selected from PA11, PA12, PA612, PA1012 and PA1212. The total of parts by mass of the constituents (a), (b) and (c) is 100, and moreover at least 20 parts by mass in the total of the constituents (a) and (b) are constituted of a monomer unit derived from a combination of a caprolactam and/or a hexamethylenediamine/ adipic acid, while at least 20 parts by mass in the total of the constituents (b) and (c) are constituted of a monomer unit derived from a combination of an ω-amino undecanoic acid, a lauric lactam and the hexamethylenediamine/1,12- dodecanoic diacid.
