These materials melt during heating, and without containment, deform and lose structural integrity. Another major challenge is gas evolution during stabilization and carbonization, generating voids. This study introduces a new stabilization method, termed high-pressure stabilization in press (HiPSiP), which is performed directly during a compression molding process. After initial molding at 280 °C and 10 MPa for 30 min, the pressure and temperature is ramped up to 100 MPa and 510 °C and held for 1–3 h inside the mold before cooling. After HiPSiP, the matrix no longer exhibits thermoplastic behavior, due to cross-linking of the polymer chains. This prevents distortion and gas-induced decompaction during subsequent carbonization. Carbonized samples reached a density of 1.53 g/cm³ and achieved short beam strength of 28.4 ± 0.6 MPa, one of the highest to the authors’ best knowledge without the use of any densification cycles. Characterization was performed for thermal, microstructural, chemical, and mechanical properties, using thermogravimetric analysis (TGA), differential scanning calorimetry (DSC), optical microscopy, scanning electron microscopy (SEM), powder x-ray diffraction (PXRD), elemental analysis (EA), Fourier transform infrared spectroscopy (FTIR), and short beam strength testing.

This study systematically investigates the compression response of MPCFs with varying graphite microstructures by innovatively combining in-situ micropillar compression experiments with molecular dynamics simulations. Results elucidate the critical roles of grain size, orientation, amorphous carbon content, and pore structure in governing compression behavior. Specifically, as graphitic microcrystals develop, increased grain size and enhanced orientation induce collective buckling of graphitic sheets. Meanwhile, reduced amorphous regions and highly oriented pores weaken lateral support, promoting extensive sheet reorientation and leading to shear or kinking failure at lower stress levels. Consequently, the compressive strength of MPCFs decreases from 1273 MPa to 454 MPa, with fracture morphology transitioning from uniform microcracks to axial cracks along (002) planes. Correspondingly, the compressive strength of their polymer composites declines by 57.9 %, with the failure mode shifting from matrix-dominated shear delamination to penetration damage caused by brittle fracture of fibers.

Utilizing polymethacrylimide (PMI) foam as a three-dimensional scaffold, multi-walled carbon nanotubes (MWCNTs) as a conductive network, and two types of Fe₃O₄ hollow nanospheres synthesized via hydrothermal and solvothermal methods as magnetic loss components, we constructed a “magnetic–dielectric–porous” composite foam.

Furthermore, UV-initiated polymerization was employed to increase the precursor viscosity, effectively suppressing filler settling during processing.

Thorough evaluation of localized responses is of paramount importance for overall structural analysis.

Herein, off-axis tests were performed on woven carbon fabrics in polycarbonate (PC) matrix that have been per-sheared to simulate yarn reorientation. A transition from brittle to ductile characteristics was found as yarn angle increased. High-fidelity mesoscale representative volume elements (RVEs) were developed to examine this transition as well as the progressive failure of composites. An elasto-plastic constituent model was established for the PC, and modified strain-based 3D Hashin failure criteria with viscosity regularization were employed for yarns to facilitate convergence in response to PC plasticity-induced large deformation of composites. In agreement with the experiments, RVEs with small yarn angles (30°, 37.5°) exhibited near linear mechanical behaviors with brittle failure dominated by fiber fracture whereas RVEs with larger angles (45°, 52.5° and 60°) displayed significant nonlinearity and large deformation (nearly 40% strains). These ductile characteristics were manifestations of matrix plasticity coupled with yarns rotating to align with the load until interlocked.

This study proposes improved ROM models considering molding temperature and fiber mass fraction affecting mechanical property of jute fabric polylactic acid (PLA) composites. Plain jute fabric was alkali-treated (10 wt% NaOH, 2 h), and jute/PLA composites were fabricated by compression molding through alternate stacking of PLA with unidirectional jute yarns or plain-woven jute fabrics at different molding temperatures and fiber mass fractions. Below PLA’s melting point (160°C), insufficient matrix flowability hinders fiber impregnation, resulting in decreased composite strength. Conversely, excessively high temperatures induce thermal degradation of jute fibers, compromising the mechanical integrity of the composite, as the tensile strength of jute fabric/PLA composites decreases from 51.46 to 18.56 MPa when molding temperature increased from 160 to 200°C. The influence of fiber mass fraction on tensile strength of jute fabric/PLA composites exhibits a two-stage pattern. Increasing fiber mass fraction initially enhances the tensile strength of composites, but when it exceeds 26%, the tensile strength decreases due to inadequate impregnation.
