HIGH-PERFORMANCE FOAM CORES BASED ON PMI DEFINITION OF STATUS AND RECENT DEVELOPMENTS

摘要

The present paper defines the position of a family of already very well established rigid foams based on PMI. It will be shown that PMI is widely used as a core material for demanding sandwich structures in many fields of application, e.g. air- and spacecraft, railway rolling stock and ships. Typical applications will be discussed to characterize the performance of these particular foam plastics and to show that they significantly contribute to weight and cost savings. Most recently, two new PMI grades have been developed which will be discussed in this paper.
