ABSTRACT The evolution of double‐double (DD) laminates is a promising substitute for traditional quasi‐isotropic laminates due to their potential for lower interlaminar stresses and enhanced design flexibility. The present work investigates the low‐velocity impact (LVI) response of carbon fiber/epoxy composites experimentally and numerically. One quadriaxial (QUAD) layup and th…

ABSTRACT While the mechanical reinforcement of filler particles has been extensively recognized as a critical factor in enhancing the wear resistance of polytetrafluoroethylene (PTFE) composites, the tribological mechanisms beyond mere mechanical effects remain poorly understood for fillers within the same elemental group. This study systematically investigates the tribological…

ABSTRACT The growing demand for sustainable elastomer management has prompted the development of self‐healing cross‐linked rubbers. Recent studies showed that adding ZnO to carboxylated nitrile rubber (XNBR) creates thermo‐reversible ionic interactions. However, Zn leaching during life cycles of rubber products raises environmental concerns. Moreover, achieving both efficient r…

ABSTRACT This study investigates the effects of surface‐modified basalt fiber (BF) on the interfacial properties and mechanical performance of epoxy resin (EP) films. Surface modification was achieved using the silane coupling agent γ‐Aminopropyltriethoxysilane (KH550). KH550 was grafted onto the BF surface via the aqueous solution method to establish a “molecular bridge” effec…

ABSTRACT The thermal management demands of high‐performance electronics drive the need for lightweight composites with high thermal conductivity. Carbon fiber reinforced polymer composites offer excellent mechanical properties and designability, but their intrinsic thermal conductivity is limited. In this paper, both the thermal conductivity and thermal management performance o…

ABSTRACT The present work investigates the dynamic response of Carbon Fiber Reinforced Epoxy Reinforced Aluminum 2024‐T3 FML with a 2/1 stacking arrangement subjected to low velocity impacts. Low velocity impact tests were conducted by drop weight impact tests using hemispherical impactor at an impact energy range of 60–120 J. Hybrid finite element modeling of the laminate in A…

ABSTRACT Literatures show that vibrations induced by foreign object impacts on composite laminates influence delamination formation under multiple impacts. To further investigate this effect, composite laminates with different curvatures subjected to two identical ice sphere impacts at different locations were investigated. Based on a previously established and experimentally v…

ABSTRACT Fast‐growing poplar is a renewable hierarchical porous material; however, its low mechanical strength, poor toughness, and high moisture affinity limit its application in structural fields. In this work, a hyperbranched epoxy resin/modified silica sol hybrid system was developed as an organic–inorganic reinforcing phase and introduced into poplar wood via vacuum‐pressu…

ABSTRACT Improving the fracture behavior of composite materials without compromising their mechanical performance remains a key challenge in structural applications. In this work, the effect of a nanostructured interlayer based on graphite nanoplatelets (GNPs) on the interlaminar shear strength (ILSS) and fracture toughness (Mode I and Mode II) of carbon fiber‐reinforced polyme…

ABSTRACT Order‐aligned structures of thermally conductive fillers in the matrix are of great importance for the highly effective thermal interface materials (TIMs) in the fields of electronic devices, semiconductors, and electronic packaging. However, achieving high thermal conductivity via constructing ordered structures with low filler content remains challenging. Here, we co…

ABSTRACT The bending stiffness of unidirectional (UD) prepregs is non‐constant and temperature‐dependent, playing a critical role in wrinkle formation during preforming. Therefore, establishing a temperature‐dependent constitutive model to capture the bending behavior is essential for accurately predicting wrinkling defects. In this study, the temperature‐dependent evolution of…

ABSTRACT Expanded polystyrene (EPS) is widely used in packaging because of its low density and excellent shock‐absorption and thermal insulation properties. However, its hard‐to‐recycle nature leads to severe environmental pollution. In this study, EPS waste was upcycled to develop lightweight, high‐performance wood–plastic composites (WPCs) using bamboo fibers and pulp. EPS wa…

ABSTRACT The brittleness of fiber‐reinforced polymer composites (FRPs) makes it difficult to balance their strength and toughness, resulting in no nonlinear warning phenomenon like metal materials before ultimate failure. By optimizing the fiber hybrid proportion, the damage mechanism of the FRPs can be effectively changed, enabling them to exhibit a nonlinear progressive damag…
