The aim of this paper is to investigate adhesion property between nano-layered filler and the polymer matrix using a combination of experimental and micromechanical models as well as the changes in yield strength and stiffness of a layered silicate-filled epoxy nanocomposite. The results indicate that addition of intercalated layered silicate particles increased Young’s modulus and yield streng...

Strain-rate effects in a unidirectional non-crimp fabric carbon/epoxy composite are addressed. To allow for kink-band formation including strain-rate and damage such composites, the paper advances recent model focused on compression loading at small off-axis angles. The is based computational homogenization with subscale represented by matrix fibre constituents finite deformation. constituent a...

This study evaluated the potential of using poly(lactic acid)/poly(e-caprolactone) (PLA/PCL) blends for fused filament fabrication (FFF) and assembly with pure PLA biomedical applications. PLA/PCL binary were meltblended in a twin-screw extruder at different ratios (20/80 to 80/20) then formed into filaments calibrated diameter FFF. The microstructure, surface properties, rheological mechanical...

In this paper, the modal and linear buckling analysis of a laminated composite drive shaft reinforced by 11 multi-walled carbon nanotubes (MWCNTs) was carried out using an analytical approach, as well finite element method (FEM). The theoretical model is based on classical theory (CLT). fundamental frequency critical torque were determined for different fiber orientation angles. Halpin–Tsai emp...

Biocomposites based on thermoplastic polymers and natural fibers have recently been used in wind turbine blades, to replace non-biodegradable materials. In addition, carbon nanofillers, including nanotubes (CNTs) graphene nanoplatelets (GNPs), are being implemented enhance the mechanical performance of composites. this work, Mori–Tanaka approach is for homogenization a polymer matrix reinforced...

The purpose of the present work is to analyze the modulus of elasticity of graphene (Gr) sheet-reinforced metal matrix nanocomposites (MMNCs) using a homogenized model based on the Mori-Tanaka micromechanics approach. The main focus is to investigate the effects of Gr sheet agglomeration on the MMNC macroscopic elastic modulus. Also, the role of aligning Gr sheets in the mechanical performance ...

This work focuses on the assessment of oil palm mesocarp fibers as reinforcement in a composite material with an unsaturated polyester matrix. Several volume ratios OPMF (0 to 15%) were used, being distributed randomly. The resulting was characterized physical and mechanical aspects. Physically, true apparent densities determined well porosity rate. It appears that addition further lightens inc...
