By means of speeding up the aging of the EIP and transient pulse test, the temperature-rising curve of EIP, the variation of the ignition pressure and 50% ignition point are obtained.
The analyses of the aging hardness curve of the composites showed that the additions of Al-silicate short fibber accelerated aging and there were double hardness peaks on the hardness curve.
