Abstract
Curved beams tested in four point bending were used to measure interla minar tensile strength, and straight beams loaded in three point bendi ng to measure interlaminar shear strength. Results from specimens of 1 6, 32 and 64 plies with all dimensions scaled showed significant size effects. The average interlaminar tensile strength dropped from 109 MP a for the smallest specimens to 61 MPa for the largest, whilst the int erlaminar shear strength was reduced from 97 MPd to 85 MPa.
