“…From the results obtained, the addition of the fillers improved the compressive strength 69%, while the Young's modulus increased from 446.56 MPa to 872.56 MPa, as the fillers loading increased from 10 to 30 wt.%. Similar result was reported by [16], when the addition of the rigid nanoparticles increases compressive yield strength of matric resins 89.1 MPa at 0 wt.% to 94.78 MPa at 20 wt.%. These results can provide essential information in composite board production for industrial applications, mostly in the construction industries.…”

“…Each sample was placed unidirectional under the compression loading cell of the Universal Testing Machine (Testometric model), ensuring that the sample was at alignment with the loading cell. The compression was done according to ASTM D3410 standard, at a cross head speed of 1.5 mm/min [16][17]. As the compression of each sample by the machine progressed, a stressstrain curve was plotted automatically by the Machine (Fig.…”

The compressive behaviours (compressive strength, compressive energy, Young’s modulus, failure time, and compressive strain) of epoxy composite board, reinforced with oil bean pod shell particulates (OBPS) and mahogany timber saw dust (SD) were investigated in this research. The samples were prepared with five different fillers (OBPS and SD) percentage (10, 15, 20, 25 and 30 vol.%) in the ratio of 1:1. Both filler materials where treated with 5(w/v)% Sodium hydroxide solution to enhance their mechanical properties. All the composite samples were tested according to ASTM standards, by using the Universal Testing Machine. Results obtained from the research showed that fillers loading had significant (P ≤0.05) effect on all the compressive behaviours investigated. In addition, the results showed that the fillers significantly improved all the compressive parameters. The compressive strength of the composite increased from 14.54 to 48.19 MPa, as the fillers loading increased from 10 to 30 wt.%, while the Young’s modulus increased by 49%. The compressive energy increased from 21.4 to 146 Nm. Data gotten from this research can be useful in the production of composite boards for engineering applications.

“…To avoid the composite from failures, suitable reinforcing agents should be applied to the matrix, which gives the additional properties that, the composite need [4]. Matrix modification is one of the processes to strengthen the matrix phase and improve the composite's properties [5]. This matrix modification process can be done by reinforcement of the second phase mainly (Nano-tubes, Nano-wires, Nano-particles, etc) to the matrix, which can alter mechanical, physical and chemical properties [6].…”

The objective of present research work is to investigate the surface morphology and surface microhardness of unidirectional E-glass fiber epoxy composites filled with varying amount of ZnO nanofiller content such as 1, 2, 3, 4 and 5 wt% respectively. ZnO nanofiller was added to the epoxy resin matrix in varying amount (wt%) using mechanical stirrer and followed by ultrasonication process. The laminate composites were fabricated using a compression molding press technique. Further, laminate composites were subjected to individual characterization and testing according to ASTM standards. The crystalline nature of ZnO nanofiller was studied using x-ray diffraction analysis (XRD) and surface morphology of ZnO nanofiller on the resin surface was examined by using a scanning electron microscope (SEM). The experimental test results revealed that addition of nanofiller content by 1, 2 and 3 wt% resulted in a gradual reduction of void fraction and thereafter increase in void fraction was observed with 4 and 5 wt% of ZnO loading. The surface microhardness results indicated a linear increment with increase in ZnO nanofiller loading from 1 to 5 wt%. Further, surface topography was studied with the help of atomic force microscopy (AFM), to obtain the surface roughness values. The surface roughness values increased with increase in ZnO wt% within the epoxy resin matrix. The results of the surface analysis of the fabricated composites indicate that at higher loading of ZnO nanofiller, there is formation of clusters and agglomerates of the nanofiller which reduces the nano-scale effects of the filler and nanofillers tend to behave as micro-fillers.

In this study a type of polymeric composites from melting poly Unsaturated polyester as a basic substance with powdered sawdust was prepared, studying some of it is mechanical properties, which was included: Impact Strength (I.), Yong modulus (E), hardness (B.) and compression Strength (C.). Polymeric composites before and after reinforcing were studied by comparison between them. It was noticed increasing resistance of Yong modulus (E), Impact Strength (I.), hardness (B.) and compression Strength (C.). Also, It is studied the effect of some acids like (, H2SO4, HNO3) with concentrations (0.5 N; 1N and 1.5N) respectively. Some physical properties were studied as absorbance and poly 's diffusion coefficient before and after reinforcing. The results showed increases in values of these properties with increasing concentration of acid and time of polymer's immersion in the acidic solution.
