Special Issue Information

Dear Colleagues,

Polymeric materials are increasingly receiving scientific and industrial interest due to the recent advances in 3D-printing techniques and the possibility of introducing smart responses under various external stimuli. Among the industrial sectors, we find interesting applications for biomedical devices, aeronautical components, and smart structures for soft robotics. The mechanical behaviour of these fast-growing materials is rather complex, combining nonlinear large deformations, strain rate and temperature dependences, as well as viscoelastic and viscoplastic responses. When these materials are manufactured by 3D-printing techniques or when they include embedded stimuli-responsive particles, their mechanical responses become even more complex, presenting anisotropy and physically coupled effects. All these dependences together make the characterization and modelling of their mechanical deformation and failure extremely difficult.

In this Special Issue, novel and recent trends in the Characterisation and Constitutive Modelling of Polymers and Polymeric Composites will be highlighted and discussed. A special focus will be placed on smart polymeric composites (e.g., magneto-active, electro-active), 3D-printed polymers, and polymeric metamaterials. This Special Issue will cover experimental, modelling, and computational aspects of the area.

It is my pleasure to invite you to submit a manuscript for this Special Issue. Full papers, communications, and reviews are all welcome.

This paper reported the tensile failure strengths and damage procedure of composite laminate manufactured from the toughened-epoxy T800 prepreg at multi-scale levels. According to the exterior and interior distinction of each layer in laminate, the macro/mesoscale representative volume element (macro-RVE, meso-RVE) was first constructed, respectively. Then the micro-scale representative volume element (micro-RVE) with a hexagonal fiber-packed pattern in the interior zone of each layer in the laminate was finally determined on the principle of the same fiber volume fraction between the composite laminate and multi-scale RVEs. In the multi-RVEs analysis, the mechanical failure strengths of each scale model were transmitted from the last-scale model’s homogenization, such as the meso-RVE from micro-RVE and the macro-RVE from meso-RVE. Based on our previous report, the innovative multi-scale damage and post-damage models on the concept of the smear crack were improved fully and incorporated by user-defined material subroutines (UMATs), such as in the addition of multiple cracks co-coupled, which makes it predict the element damage procedure. The averaged mechanical responses with damage mechanism of multi-scale RVEs under tensile, compressive, or shear loadings were obtained wholly by the homogenization method. The macroscale tensile damage initiation and propagation procedure were analyzed in detail including their global/local responses, being extended to comparison with experimental results. Full article

The surface roughness (Ra) and composite interfacial property of carbon fiber (CF) are considered to be mainly affected by the microstructure of the CF surface. However, quantitative characterization of the CF surface microstructure is always a difficulty. How the CF surface microstructure affects the interfacial property of CF composites is not entirely clear. A quantitative characterization technique based on images was established to calculate the cross-section perimeter and area of five types of CFs, as well as the number (N), width (W) and depth (D) of grooves on these CF surfaces. The CF composite interfacial shear strength (IFSS) was tested by the micro-droplet debonding test and modified by the realistic perimeter. The relationship between the groove structure parameter and the Ra, specific surface area and composite interfacial property was discussed in this article. The results indicated that the CF cross-section perimeter calculated by this technique showed strong consistency with the CF specific surface area and composite interfacial property. At last, the composite interface bonding mechanism based on defect capture was put forward. This mechanism can be a guiding principle for CF surface modification and help researchers better understand and establish interface bonding theories. Full article
