Material Properties of Pultruded FRP Profiles
The relatively low elastic moduli of pultruded FRP profiles often results in their design being governed by deflection and buckling criteria. Their relatively low shear moduli may also result in shear deformation constituting a significant proportion of the total deformation and a reduction in global and local buckling loads. Determination of the various elastic moduli of pultruded FRP profiles, from full section and coupon tests, is described. Results of the various tests and theoretical predictions are compared and exhibit significant variation. Explanations for the differences are provided and recommendations made concerning appropriate properties to be used in design.
