8、2001(E) iv ISO 2001 All rights reserved Foreword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member bo
9、dy interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrot
10、echnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Pu
11、blication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this part of ISO 1268 may be the subject of patent rights. ISO shall not be held responsible for identifying any or all su
12、ch patent rights. International Standard ISO 1268-7 was prepared by Technical Committee ISO/TC 61,Plastics, Subcommittee SC 13,Composites and reinforcement fibres. Together with the other parts (see below), this part of ISO 1268 cancels and replaces ISO 1268:1974, which has been technically revised.

The fibre reinforcement may be preformed. The reinforcement is placed in the cavity of the mould and the mould is c
22、losed. The resin system is injected into the cavity to impregnate the reinforcement. Subsequently, the resin is cured to form a composite plate. The procedure can be modifed, for instance by applying a vacuum to extract the air prior to resin injection, heating the resin to reduce its viscosity and
23、curing time or, when the resin is a highly reactive one, introducing the resin and hardener separately, using two pumps, into a mixing chamber and then into the mould. -,-,- ISO 1268-7:2001(E) 2 ISO 2001 All rights reserved 5Materials 5.1Reinforcement Reinforcement fibres, such as glass, carbon, ara
24、mid, etc., in the form of mats (chopped-strand or continuous-strand mats), chopped rovings, woven fabrics, knitted fabrics, braids, unidirectional reinforcements and combinations thereof can be used. The reinforcement may be preshaped into a preform in such a way that it retains its shape. Preforms
