Rapid prediction of fibre-dominant tensile failure in randomly oriented strands

A stochastic morphological modelling framework has been established to predict the tensile behaviour of Randomly Oriented Strands made ultra-thin Carbon Fibre Reinforced Thermoplastic prepreg tapes. The tape properties from their distributions are generated in a Monte Carlo simulation. Young’s modulus laminate is accurately predicted using classical theory. Fibre-dominant failure also Thermoplastics Sheet Moulding Compounds Weibull Material discontinuity accounted for via introduction stress concentration factor, as result overlaps. strength values and scatter were found increase with increasing length, which agrees well literature data, thus demonstrates reliability proposed framework. rapid well-suited application structures.
