  • Patent number: 5234752
    Abstract: In a wear-resistant laminated article (e.g. a bearing, or a compressor rotor blade) made by heating an assembly of superimposed layers of fabric impregnated with a phenolic or other thermosetting resin, the fabric is made of non-asbestos yarn comprising a core of glass fibre with a surface of aramid fibre and a relatively porous fibre such as viscose fibre, the aramid fibre forming not more than 40% by weight of the yarn. The laminate may further incorporate carbon fibres.
    Type: Grant
