摘要： In an example, a method for forming a composite part includes, based on a part specification, cutting layers of material in a sequence and positioning the layers to form a stack. For each layer, after positioning the layer and before cutting a next layer in the sequence, the method includes (i) scanning along a length of the layer to determine an image, (ii) determining, based on the image, at least two edges of the layer, (iii) determining, based on the edges, a measured width at locations along the length of the layer, (iv) comparing the measured width at each location to a target width at the location, (v) deciding, based on the comparison, whether to adjust the production process, and (vi) if the decision is to adjust the production process, then adjusting the production process based on the comparison. The part specification specifies the target width at each location.

摘要： The present invention is a method for real-time controlling a resin transfer molding process, which is used to control a filling pressure of a resin in a resin transfer molding (RTM) apparatus. In a pre-control RTM process, the current filling pressure, the current permeability and the wave front position at the current time point is input into a prediction-control model to acquire a predicted filling pressure at the next time point. The predicted filling pressure is used as the filling pressure to make the resin flow to the expected position of the wave front at the next time point, whereby to achieve stable quality of RTM products.
