Requirements of New Polymeric Materials for Heavy Service Conditions

Abstract

The concept “property” is discussed in the light of the service conditions of the material. The presently existing polymeric materials are reviewed as regards their rigidity, strength, thermo-stability and resistance against chemical deterioration. Homo-polymers can fulfill the requirements for extreme service conditions only partly, viz in the form of fibers, films and elastomeric tubes, but not as all round engineering materials. For the last mentioned category a special balance of properties is required: light weight in combination with very good mechanical, thermal and environmental properties in all directions. Composite systems provide a satisfying solution provided that the adhesion between matrix and reinforcement is very good. New methods of fabrication and application will have to be worked out assuring economical use in competition with other engineering materials, e. g. metals and their alloys.
