In our study, a new kind of material was prepared by melt blending with PVC as the matrix and carbon black (CB) as the filler. With the amount of CB increasing, the notched impact strength of composite increased greatly, however the tensile strength declined. When the amount of CB was 30%, the notched impact strength of composite was 9.66 KJ/m2, the tensile strength dropped from 48.3MPa to 33.2MPa. The distribution of CB in the PVC matrix is relatively uniform and no large agglomeration in the PVC matrix.

Efforts have been made to turn empty water sachet (commonly called pure water nylon), palm kernel shell and iron filings, which are all wastes released into the environment from different sectors of production in Nigeria into a useful material of good physical and mechanical properties. These wastes, especially the empty water sachet, pose a great challenge on the effort of achieving a clean and safe environment, mostly by their contribution to flooding during the rainy season. A recycling aimed research was carried out, making use of these materials to produce a new composite material and proffer suggestions for the possible use of the newly developed composite material. The empty water sachet was used as a matrix, which was reinforced by carbonized palm kernel shell particulate and iron filings. The percentage composition of iron fillings was maintained at 5%wt, while that of palm kernel shell ash was varied from 5%wt - 20%wt at an interval of 5%. The composites were compounded and compressively moulded. Physical and mechanical properties of the composites were tested for and the results obtained shows that the composite material could be used to produce automobile bumper among other parts due to their Impact Strength and low Density. After results analysis, materials with 5%wt of CPKS and that with 10%wt of CPKS were recommended for the automobile bumper production following their high impact strength - density ratio of 0.26 and 0.19 respectively, which are higher as compared to that of Peugeot 406 bumper measured alongside the composite materials.

Abstract The present study describes the preparation of aligned unidirectional bagasse fiber-reinforced vinyl ester (BFRVE) composites and their mechanical properties such as tensile, flexural, shear and impact strength. Composites were prepared by a hand lay-up technique developed in our laboratory with the help of a hot press. Mechanical properties were obtained for different fiber contents by varying the number of layers. The obtained tensile property values were compared with the theoretical results. The results show that the tensile strength increased linearly up to 44 wt% and then dropped. However, the tensile modulus increased linearly from 17 wt% to 60 wt%. In the case of flexural properties, the flexural strength increased up to 53 wt% and started to decrease. However, the flexural modulus also increased linearly up to 60 wt%. The impact strength values were higher than the matrix materials for all the specimens. The short beam shear strength values were also increased up to 53 wt% and then dropped. The modified Bowyer and Bader (MBB) model followed by the Hirsch model shows a very good agreement with experimental results in both tensile strength and modulus.

In this work, hydroxyapatite (HAp) was produced from crocodile bones by thermal process at 900°C. X-ray diffractometer (XRD), Fourier transform infrared spectrometer (FTIR) and Scanning electron microscope (SEM) were used to characterize the obtained HAp. Polylactic acid (PLA)/HAp composites were prepared by melt blending as follows: 95/5, 90/10 and 85/15 (weight ratio). The effect of the amount of HAp on the mechanical properties including tensile strength, modulus, elongation at break and impact strength of PLA/HAp composites was undertaken. It was found that tensile strength and elongation at break of the composites decreased with an increase of HAp content, while modulus and impact strength showed no significant effect.

The wood-plastic composites (WPC) were prepared via compress molding by using the blends of high density polyethylene (HDPE) and modified polyethylene (MAPE) as the matrix and wood flour (WF) as filler. The effect of MAPE content in the matrix on the mechanical properties of the matrix and WPC was investigated. It was shown that the change of MAPE content in the matrix had no influence on the tensile strength of the matrix, but markedly reduced the impact strength of the matrix. Additionally, it had significant influence on the strength of WPC. When the content of wood flour and the content of the matrix remained fixed, with increasing the content of MAPE in the matrix, the tensile strength and the flexural strength of WPC tended to increase rapidly initially and then become steady. Moreover, with the increasing of MAPE concentration, the impact strength of WPC decreased when the low content of wood flour (30%) was filled, but increased at high wood flour loading (70%).

Reinforcing Material

Kenaf is a nonwoody fibrous plant, and its fibre can be potentially used as a reinforcement in the matrix to produce biocomposite materials. The properties of biocomposite materials are highly dependent on the reinforcing material and the matrix used as a binder. This study used kenaf fibre as a reinforcing material with different compositions (10, 20, and 30 wt.%) and different fibre lengths (1 cm and 3 cm) in the matrix using the casting process. Low viscosity epoxy resin (635 thin epoxy resin) with a viscosity of 6 poise was used as the matrix. The results showed that the highest flexural strength, impact strength and shore hardness were obtained at a 30 wt.% kenaf fibre composition with a 1-cm kenaf fibre length, namely, 85 MPa, 338 KJ/m2 and 98 SHD, respectively. The length of the fibre in the matrix affects the mechanical properties of the resulting biocomposite. This condition is caused by kenaf fibres with a length of 1 cm being more dispersed in the matrix than fibres with a length of 3 cm.

This study aims to examine mechanical properties of biocomposites formulated with virgin/recycled acrylonitrile butadiene styrene (ABS). Neat virgin ABS (VABS), neat recycled ABS (RABS), VABS with 15% palm long fiber (VABS/15PLF), and RABS with 10% palm short fiber (RABS/10PLF) were fabricated and examined. Twin extruder machine was used to manufacture granular composite. Impact, tensile, and hardness tests were carried out. This study found that the incorporating palm fiber into the matrix polymer increased brittleness of the composites. Impact strength of the composites increases with the rise filler loadings. Increasing filler loading in VABS was found to be able to increase the composite hardness. Conversely, for RABS, the composite hardness was found to decrease with the rise filler loadings.

The current study investigates on development of hybrid composite with Kenaf/Kevlar as reinforcement and unsaturated Polyester as the matrix considering stacking sequence, the orientation of fabric and twill 2x2 weave of the Kenaf fabric in particular. Five laminates (L1, L2, L3, L4, and L5) were developed by stacking the lamina's one over the other with the matrix and then cured in an autoclave. The laminates were subjected to experimental investigation to evaluate mechanical properties such as tensile strength, flexural strength, hardness, and impact strength. Results indicate that L5 shows good flexural strength and modulus, high hardness, and good impact strength, whereas L4 indicates the best tensile strength and tensile modulus. To summarize, the hybridization resulted in an average of 30% increased mechanical property for Laminate L5. The effect of stacking in L5 has a significant impact on the property of the composite. The results of the study were mainly focused on minimizing the use of synthetic fiber and replacing it with natural fiber. SEM analysis was performed on fractured surfaces of specimens which revealed that the failure of the laminated composite is due to poor interfacial bonding among fiber and matrix. Overall, the composite obtained from the combination of Kenaf and Kevlar fabrics had the best balance of properties finds appropriate application for car bumpers, fenders, boat hull, turbine blade etc.
