The Automotive ceramic gas turbine(CGT) is intended for operation at a turbine inlet temperature of 1,350°C and a turbine speed of 100,000 rpm. High temperature lubricating oil has to satisfy the heat-resistant and lubricity under a severe condition such as a bearing temperature of 300 °C, a reduction gear tooth pressure of 1 GPa and a peripheral speed of 120 m/s. The practical performance and durability tests of the high temperature lubricating oil based on polyolester were performed using a high-temperature and high speed bearing simulator and a high speed gear tester under the actual engine conditions.

The present paper outlines basic material models for composite strength and failure analysis, based on ESI's PAM-FISS/Bi-Phase composite material model. The new material models have been ported into the PAM-CRASH™ crashworthiness simulation code and applied to the crashworthiness simulation of axially compressed box columns made of hybrid Carbon-Kevlar-Aramid sandwich walls. After calibration of the models on laboratory coupon tests and validation on simple component crash tests, the methodology can be used to predict the crash behaviour of a prototype passenger car compartment structure, made entirely of composite sandwich material.
