Abstract

The temperature dependence of the thermal strains in the longitudinal direction of the transverse ply ε thtl , of 0°/90°/0° epoxy and polyester laminates, has been determined from the thermal variation of the deflection of an unbalanced beam. These results have been compared with those predicted from known values of the linear expansion coefficients,α t andα l. There is good agreement between the experimental and calculated values of thermal strain for the epoxy composite. Good agreement for the polyester laminates can only be obtained when the values ofα t used are those for wet laminates. The large thermal strains previously reported for the polyester laminates can therefore be explained by small quantities of water in the matrix which are not readily removed during post-curing.
