“…In line with other published works, the test specimens for impact test were prepared according to ASTM D 256M and all the specimens were notched with a root radius 0.25mm at 2mm depth and the composite specimen were 70mm long, approximately 2mm thick and 10mm wide [22,23]. The impact speed was set at 3.6 m/s, employing a hammer drop energy of 7.7 J and span in-between the supports was stationed at 40 mm.…”

The primary objective of this research work is to analyse the effect of fibre loading and orientation on the tensile and impact strength of the polymeric composite materials. Fibre reinforced composite materials have been reported to have attracted many applications in view of its low weight and superior strength when compared with the metal matrix composite. While researches have established the weight reduction of fibre reinforced polymer material, few works have reported the impact of orientation on the manufacturing of polymer composite. In this study, series of experimental works were done to demonstrate the manufacturing of glass-fibre reinforced epoxy resin with special attention on the influence of oriented reinforced composite material. The composites were manufactured using hand-lay technique with three different fibre loadings (10, 20, and 30 wt. %) and at two different fibre orientations (30o and 60o). Key of the finding drawn from this research form the basis of discussion and, composite with 60o fibre orientation showed better tensile strength when compared with the neat resin and other oriented (G10E30) fibre reinforced composite. Similar observations were also noticed on the impact strength of these composites which signify the improved mechanical properties of oriented reinforced composite materials.Â http://dx.doi.org/10.4314/njt.v36i3.17

“…The square plate mould with dimensions: 480 × 480 x 3 mm was specifically fabricated for the development of the specimen test in line with other published works [13,14] assembled with base and top plates, for the easy removal of the specimen, without sticking. The mould cavity was thoroughly cleaned in order to avoid particles interaction with the epoxy resin and were coated the inner layers of the mould with polyvinyl alcohol (PVA), for easy removal of the composite specimens.…”

Replacing external metallic wall of refrigerated vehicles has been on the front burner in many published works as weight of the metallic insulated panel continues to pose a challenge on refrigeration unit and environment. As a follow-up to this problem statement, five (5) composite materials were fabricated as replacement options for metallic external sheet for refrigerated vehicles. The key study of this paper is to investigate the moisture absorption and thickness swelling tendencies of these composite specimens as these properties determine the suitability of these materials for refrigerated wall. Part of the methodology adopted in the manufacturing of these composites were based on fibre loading and orientation in the composite panel. Key findings from this experiment shows that the absorption behaviour of composites at 30 o and 60 o was consistent until 60 hours duration of immersion before a significant disparity was observed. In addition, G30E (30% reinforced glass fibre in the epoxy composite) was more resilient to moisture attack as a result of enhanced fiber content. The implication of the study is that G30E reinforced composite material could be adopted as external wall of food transport system because of its lower thickness swelling and water absorption properties.

“…Introduction. Epoxy polymer is one of the most applicable thermoset matrices used for reinforced composite materials, due to its high elastic modulus, considerable rupture strength, low creep and good performance at elevated temperature [1][2][3]. Despite the above improved characteristics, epoxy materials have a brittle nature, low toughness, and poor damping characteristics [4].…”
