Experimental and theoretical investigation on tensile properties and fracture behavior of carbon fiber composite laminates with varied ply thickness

Unidirectional laminate made from ply prepreg is commonly used to evaluate the mechanical performance of carbon fiber-reinforced composites (CFRCs), which is often calculated using the classical law of mixtures based on the fraction of dual-phases components. The thinning of the ply prepreg presents some special influences on composite structures and mechanical properties, leading to the deviation of the results between calculation and the...
