“…Because of the peculiar mechanical properties and failure mode of the thermoplastic materials, their numerical simulation is still an open point 5 . In this work, starting from experimental data, a multi‐scale approach is implemented in order to simulate the behaviour of a polypropylene (PP) woven lamina used for the production of a thermoplastic composite material.…”

In this work, the behaviour of a woven lamina for thermoplastic composite material is experimentally and numerically investigated. A thermoplastic composite made of hot‐pressed polypropylene (PP) woven laminas is the object of the study. The laminas are composed by tapes that are made up of coextruded core and skins. Experimental tests were carried out to determine the properties of the lamina. The experimental data are used to develop numerical models for the simulation of the experimental test. Three modelling techniques are proposed: The first one implements a macro‐mechanical material model, the second one uses a meso‐mechanical approach, and the third one discretizes the geometry at the yarn level. The global response of the meso‐mechanical material model showed the best agreement with the experimental test, even if it does not represent the optimal solution from the computational cost point of view.

“…XC. Sun [2] studied three different LS-DYNA finite element analysis (FEA) models in simulating low-velocity impact damage for two carbon fiber materials, and all the models provided reliable predictions. Post-failure behavior modeling is the key to composite damage prediction, so researchers like P. F. Liu et al [3,4,5,6,7,8] explored different methods to predict the intraluminal and interlinear damage.…”

Unidirectional carbon fiber composite material is one of the most common types of composites employed in vehicles, and its bending performance plays an important role in crash safety, especially in side pole impact. This study aimed to redesign one of the most important components of the side structure of a vehicle, the rocker panel, with unidirectional carbon fiber composite material. Our results show that it is not easy to acquire the same bending performance as that of a steel rocker panel by merely replacing it with carbon fiber material and increasing the wall thickness. Therefore, reinforcements were employed to improve the bending performance of the carbon fiber rocker panel, and a polypropylene reinforcement method achieved a weight reduction of 40.7% compared with high-strength steel.

“…This type of quality control testing is generally preferred by industry to characterize the toughness of thermoplastic polymers [2]. Measures the ability of a sample or end piece to withstand sudden loads, is a quick test but the impact resistance is dependent on the method used [3]. Among the main factors affecting the measurement are the shape and geometry of the impactor.…”

This article presents the results of the mechanical characterization of the impact resistance of PETG and PA6 thermoplastic polymers. This type of polymer is being widely used in industrial applications and the characterization of its mechanical properties is a subject of great academic and industrial interest. The impact pendulum technique has been used as the most widely known. The tests have been carried out under different conditions and varying the greatest number of parameters in order to obtain data that allow a rigorous characterization of these materials.
