NOTES 6.1 Intended use, Polyetheretherketone (PEEK) thermoplastic materials are intended for use as a matrix for glass fiber and carbon-gra

42、phite composites, for injection molded parts and monofilament, and as insulation for electrical wire and cable. The material has very low flammability, low smoke and toxic gas emission, and resistance to gamma radiation. 6.2 Ordering data. 6.2.1 Acquisition requirements. Acquisition documents should

43、 specify the following: a. Title, number and date of this specification. b. Type and class of material. C. Specific pellet size, if required (see 3.3). d, Whether a preproduction sample is required and, if so, pertinent e, Quality conformance tests, if other than specified in 4.2.2, f, Sampling plan

44、, if other than specified in 4.2.2.2. g. Level of packing required (see 5.1). details (see 4.2.1). 6.3 Specific optical density. The maximum specific optical density, Dmax, represents total smoke accummulation. 6.4 Gamma radiation resistance. Polyetheretherketone is extremely resistant to embrittlem

45、ent by gamma radiation, Wire samples, coated with various grades (molecular weights) of PEEK polymer to a total diameter of 1.5 mm, have been exposed to gamma radiation from 6oCo spent fuel cells. Samples were removed at 250 Mrad intervals until a maximum dose of 2000 Mrad had been absorbed. The sam

46、ples were subjected to a wrap test around a 1D mandrel followed by a standard dielectric test (1.5 kv for 1 minute in water). In the range sug- gested for high performance wire covering (melt viscosity = 0.4 to 0.5 kNsm2), the dosage level of gamma radiation required to cause failure of the insulati

47、on is of the order of 1100 Mrad (11 MGy). Note: 1 rad = 0.01 gray. 6.5 Sources of supply. PEEK materials may be obtained from: a.
