Bending behaviour of thermoplastic composites in melt: A data-driven approach

The resistance to bending of continuous fibre-reinforced thermoplastic composites at processing temperature is an important predictor wrinkle formation during the stamp forming process. This can be quantified with experiments and approximated models. However, current models are validated one, or most two, composites. Hence, it not known whether these generalise other data-driven study proposes a rate- temperature-dependent model derived from experimental data 10 very different multivariate structure was analysed Tucker decomposition, together bootstrapping cross-validation, reveal generalisable trends, discard irrelevant features. suitable could parametrised yield four-parameter model, which approximates deformation, rate, dependence, respectively using linear, power law, Arrhenius-type relation. four composite materials.
