“…Furthermore, the improvement in both properties was due to partial load transfers from polymeric phase's resilience to bending loading and the interfacial interaction between the basalt fiber and the LLDPE matrix influenced by mechanical interlocking, chemical bonding and attractive molecular forces. [ 49 ] Song et al [ 50 ] had similar findings to the unmodified basalt fiber reinforced high‐density polyethylene (HDPE) composite and the results of Mazur et al, [ 16 ] who investigated the mechanical properties of basalt fiber reinforced with HDPE composites showed higher than fresh HDPE matrix. T‐GSP is a filler with strong mechanical properties, therefore when employed as reinforcement, it increases the composite's strength.…”

With the widespread use of natural polymers in composites, advances in mechanical, thermal, and thermomechanical characteristics have become necessary. This study explores, the hybridizing effect of alkali‐treated groundnut shell powder (T‐GSP) to the basalt fiber (BF) reinforced linear low‐density polyethylene (LLDPE) composites in different weight fractions. Twin screw extrusion machines were used to mix fresh LLDPE matrix with various weight fractions of T‐GSP particles (0, 5, 10, and 15 wt%) and 20 wt% of fresh BF. It has been found to be that adding up to 15 wt% of T‐GSP with 20 wt% of fresh basalt fibers in the LLDPE matrix produced better results in the mechanical, thermal, and thermomechanical properties of the hybrid composites. FE‐SEM analysis was performed on the tensile fracture surfaces of the hybrid composites to determine the effect of the T‐GSP particles on the wettability and interfacial adhesion of the fiber and the LLDPE matrix. Likewise, mechanical properties of 15 wt% of T‐GSP with 20 wt% of BF hybrid composite reported an increment of 76.39% and 397.05% in tensile strength and modulus, 230.88% and 324.70% in flexural strength and modulus. Also, a decrement of 14.32% in impact strength of the hybrid composites was reported compared to fresh LLDPE polymer. Shore D hardness testing recorded a 27% increment in hardness, while TGA and DSC reported a reduction in degradation temperature and an increment in crystallization and melting temperature of the fabricated composites. dynamic mechanical analysis (DMA) shows an increment in the glass transition temperature of all the composites.

“…Compressive properties which include compressive strength, compressive modulus, and compressive strain were recorded and analyzed. The determination of compressive strength and compressive modulus was calculated by using Equations () and () [ 25 ] :

{normalσ}_{normalC} = F / A

E_{normalC} = {normalσ}_{normalC} / ε

Where

{normalσ}_{normalC}

is compressive strength, F is applied compressive force, A is the cross‐section area of the specimen,

E_{normalC}

is compressive modulus and ε is normal strain. The experimental data of compressive strength and modulus were plotted against the MMT nano‐clay loading for UP‐MMT nano‐clay composites.…”

The effect of montmorillonite (MMT) nano-clay as reinforcement in unsaturated polyester resin (UP) matrix composite was investigated under compression loading to explore the impact of MMT nano-clay wt% in the compressive behavior of UP-MMT nano-clay composite. UP-MMT nano-clay composite samples were prepared with a varied filler content of 0.5 to 3 wt% using dualmixing methods, which are mechanical stirring and ultrasonic agitation.Static uniaxial compression tests were conducted using cylindrical-shaped samples to obtain the compressive behavior of the UP-MMT nano-clay composites. The results of experimentation record a considerable improvement in compressive characteristics of UP-MMT nano-clay composites compared to pure UP matrix. The UP-MMT nano-clay composite samples were viewed under transmission electron microscope (TEM) to know the dispersion of MMT nano-clay in the composites. The nano-platelets were well dispersed and intercalated in the UP-MMT nano-clay composite samples below 1 wt% MMT nano-clay loading. The optimum wt% of MMT nano-clay in the UP-MMT nano-clay composite for improved compressive stress at yield and modulus were noted as 0.60 and 0.61 wt% respectively. Moreover, a mathematical model using Halpin-Tsai-Jumahat equations was utilized to predict the compressive properties of UP-MMT nano-clay composites, which are in closer agreement with the experimental results.

“…11,15,23,24 Generation of reactive functional groups on the surface of inorganic fillers via modification by polydopamine or coupling agents such as silanes and introduction of maleic anhydride-grafted copolymers as compatibilizers are able to enhance the dispersion of the inorganic particles. 12,[23][24][25][26][27][28][29] Moreover, application of appropriate compatibilizers can increase the interfacial adhesion between the fillers and the polymer, which is favorable to improvement of tensile properties of composites. 28,29 For example, the tensile strength of 80 wt% ultra-highly wood fiber-filled polyethylene composites can be increased by 224% via using maleic anhydride grafted polyethylene (PE-g-MAH) as the compatibilizer.…”

Transportation of acidic fluids containing hydrogen sulfide (H2S) by flexible reinforced thermoplastic pipes can cause safety problems due to diffusion of H2S in the pipe. Herein, high‐density polyethylene (HDPE) composites are prepared with a large amount of zinc oxide (ZnO) particles as absorbent fillers by melt‐mixing via introducing maleic anhydride‐grafted polyethylene (PE‐g‐MAH) and maleic anhydride‐grafted poly(ethylene‐co‐octene) (POE‐g‐MAH) as dual‐compatibilizer. By controlling the mass ratio of the two compatibilizers, ZnO particles can be encapsulated by PE‐g‐MAH and POE‐g‐MAH so that mechanical properties of the prepared HDPE/ZnO composites are improved owing to enhanced compatibility between the filler and the resin. By adding PE‐g‐MAH and POE‐g‐MAH with total 10 wt% in a mass ratio of 1/3, the HDPE/ZnO composite containing 50 wt% ZnO exhibits 37.3 ± 3.8 MPa of yield strength, 576 ± 16 MPa of flexural modulus, and 84.4 ± 1.4 kJ m−2 of notched Izod impact strength corrected to 311 ± 24.9 kJ m−2. After exposure in H2S at 0.1 MPa for 7 days, the diffusion distance of H2S in the composite is 659 ± 17 μm, demonstrating a high barrier ability on H2S via absorption. This study provides a feasible method for preparation of polymer composites with suitable mechanical properties for inhibiting H2S permeation in reinforced thermoplastic pipes.
