Epoxy/unidirectional reinforcement, data

Unidirectionally reinforced [0°4]AS4/3501-6 graphite/epoxy coupons were immersed in simulated sea water at room temperature within pressure chambers at 13.8 and 20.7 MPa for 2 months and weight gain data recorded periodically up to saturation (Gao and Weitsman 1998). A third set of specimens was immersed at atmospheric pressure 0.1 MPa. Each circumstance involved at least four replicate samples. All weight data could be matched with linear Fickian predictions. Results are summarized in Table 5.1.

The S-N data of unidirectional carbon fiber reinforced epoxy, shown in the gray rectangular region of Fig. 13.11, are adapted from Ref. 69, which encompasses unidirectional carbon/epoxy data from a variety of sources. In Fig. 13.11, the maximum cyclic stress of the carbon fiber instead of that of the composite is used in order to make a comparison with the data from the present study. A... 

S-N diagrams. Filled circles are data obtained from this study. Quasistatic tensile data (square with white circle) are adapted from Ref. 33, error bar represents standard deviation. The gray rectangular region covers most S-N data for unidirectional carbon fiber reinforced epoxy composites, adapted from ref. 69.
