The last RAPRA Report on Polymers in Aerospace Applications (W.W. Wright, Report 37) was published in 1990. The present report strives to provide a contemporary review of this area with an emphasis on the literature appearing after 1990. It includes coverage of new materials and technologies (particularly nanocomposites). The principal use for polymers in aerospace applications is as a matrix material and/or reinforcing bre for composites. Other major applications include use in adhesives, anti-misting additives, coatings, elastomers, bres, and foams. | Report 192 Polymers in Aerospace Applications Joel R. Fried Volume 16 Number 12 ISSN 0889-3144 Expert overviews covering the science and technology of rubber and plastics RAPRA REVIEW REPORTS A Rapra Review Report comprises three sections as follows 1. A commissioned expert review discussing a key topic of current interest and referring to the References and Abstracts section. Reference numbers in brackets refer to item numbers from the References and Abstracts section. Where it has been necessary for completeness to cite sources outside the scope of the Rapra Abstracts database these are listed at the end of the review and cited in the text as a.1 a.2 etc. 2. A comprehensive References and Abstracts section resulting from a search of the Rapra Polymer Library database. The format of the abstracts is outlined in the sample record below. 3. An index to the References and Abstracts section derived from the indexing terms which are added to the abstracts records on the database to aid retrieval.

Authors and Akron University The effect of thermal history on the rheological behaviour of ester- and ether-based commercial thermoplastic PUs Estane 5701 5707 and 5714 from B.F.Goodrich was investigated. It was found that the injection moulding temp. used for specimen preparation had a marked effect on the variations of dynamic storage and loss moduli of specimens with time observed during isothermal annealing. Analysis of FTIR spectra indicated that variations in hydrogen bonding with time during isothermal annealing very Abstract much resembled variations of dynamic storage modulus with time during isothermal annealing. Isochronal dynamic temp. sweep experiments indicated that the thermoplastic PUs exhibited a hysteresis effect in the heating and cooling processes. It was concluded that the microphase
