Abstract

The objective of the current study is to analyse the adhesion processes between the glass fibre reinforcement layer and acrylic sheet to find out the optimal adhesion measuring methods depending on the reinforcement layer concentrations and plastic composite material parameters (dimensions, wall angles, edge radiuses). The experimental tests with different glass fibre reinforce­ment composition, material heating temperatures and adhesion area variations have been considered. For finding out the optimal adhesion measuring method different well known methods have been tested. For optimal selection of the adhesion area an optimization model have been proposed. Together with the adhesion area optimization an attempt has been made to find out the maximum tensile force, depending on the conditions and material parameters. The FEM simulation has been performed with optimal adhesion area values to verify the prediction accuracy of the surrogate model.

Keywords

large composite plastic products, vacuum forming, short glass fibre reinforcement, FEM, adhesion processes.
