The application of carbon fiber reinforced polymer (CFRP) Multidirectional (MD) laminates in aircraft structurehave motivated the manufacturers to tailor the mechanical strength in desired directions. The complex stress field owing tomultiple orientations with the loading direction increases the intricacy of failure analysis. Hence, the macroscopic andmicroscopic fracture behaviour of MD CFRP laminates under static loading needs to be explored further. In this study, fourdifferent MD CFRP laminates were fabricated using IMA/M21 prepregs by the autoclaving technique. Effect of fiberorientation on static strength i.e. tensile and compressive strength was studied. The strength decreased with the increase inorientation angle. Scanning electron micrographs revealed that irrespective of the lay-up sequence individual layers failedparallel to the fiber direction. Fiber breakage and delamination were the major failure modes in tensile specimens whilekinking, matrix failure, in-plane shear, stepped fracture, and fiber-matrix debonding were dominated in compressionspecimens. The theoretical and experimental data was in good agreement with the Weibull distribution model.
