Abstrakt: Interferometric measurements of the linear thermal expansion coefficients of epoxy resin Code 69 are reported over the approximate temperature range 90 K to 500 K. Corresponding measurements on specimens of this resin reinforced with unidirectional Courtaulds HTS carbon fibre and on specimens of resins DLS 351/BF3400 and Code 69 reinforced with bidirectional HTS fibres are also reported. The results are qualitatively similar to earlier observations on similar specimens based upon ERLA 4617/mPDA and DLS 351/BF3400 resins. A comparison of the present results with those described earlier has established that a detailed knowledge of the temperature dependence of the thermal expansion characteristics of a resin permits a good estimate to be made of the corresponding behaviour of unidirectional and bidirectional composites based upon it.
