Abstract
Curved beams tested in four point bending were used to measure interlaminar tensile strength, and straight beams loaded in three point bending to measure interlaminar shear strength. Results from specimens of 16, 32 and 64 plies with all dimensions scaled showed significant size effects. The average interlaminar tensile strength dropped from 109 MPa for the smallest specimens to 61 MPa for the largest, whilst the interlaminar shear strength was reduced from 97 MPa to 85 MPa.Keywords
