“…Glass-fiber-reinforced epoxy resin were fabricated using hand-lay-up technique and the concept of fiber orientation was specifically considered in this work in other to ascertain the water absorption and thickness swelling tendencies of the composites when compared with unoriented composites as reported elsewhere [12,15]. Newly manufactured ampreg-21 epoxy resin, which belongs to the larger family of epoxides was used as the matrix material and woven E glass fiber was used as a reinforcing fiber.…”

“…These results further enhance the mechanical properties of the resulting composite as against unreinforced composite thereby strengthening the moisture resistant property of the emerging composites. In a similar manner, Pérez-Pacheco, et al [12] investigated the effect of mechanical properties of carbon fiber/epoxy unidirectional laminated composite on exposure to humid environment and the results showed that the mechanical properties of each of the composite differs considerably as humid environment becomes more intense. The impact of fiber surface treatment and coupling agent only enhanced the fiber-matrix adhesion.…”

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.

“…Even lower rates of moisture absorption in polymers and composites results in resin plasticization, swelling, and residual stresses in the material which, in turn, are the primary sources of material property degradation. Perez-Pacheco et al [1] reported that 0.75 wt% moisture absorption resulted in reduction of the tensile strength, elastic modulus and interfacial shear strength of a carbon/epoxy composite by 25%, 38% and 11%, respectively. Pomies and Carlsson [2] reported that 1.21% absorbed water in carbon/epoxy and 0.63% absorbed water in carbon/BMI-resin reduced the transverse tensile strengths by 66% and 41%, respectively.…”

“…Moisture absorption behavior and laminate degradation of BMI resin has been addressed occasionally in varying detail [2,[6][7] but not as extensively investigated as fiber-reinforced epoxy laminates [1,[3][4][5][8][9][10][11]. In this paper, the effect of process induced voids on moisture absorption kinetics of HexPly® F650, a bismaleimide (BMI) resin reinforced with 581 style, eight-harness satin weave quartz fabric is investigated.…”

“…Relationships between polymer matrices and carbon fillers and properties of polymer–carbon composites have been extensively studied in the past decades. It was found that carbon black additive mainly improves thermal properties of composites , carbon fibers significantly enhance mechanical strength , while carbon nanotubes and graphite have positive impact on the mechanical, thermal, and electrical properties of composites . In the last years, with the development of nanotechnology, the interest in the research of polymer composites with carbon nanofibers and nanotubes and, very recently, of polymer–graphene nanocomposites has increased rapidly.…”

The influence of structural order of anthracite fillers on the curing behavior, morphology, and dynamic mechanical thermal properties of epoxy composites

et al. 2014

This article concerns the study of polymer composites with anthracite fillers of various structural order. Raw Svierdlovski anthracite of turbostratic structure and the anthracite thermally treated at 2,000°C of graphite‐like structure were used as fillers of low‐molecular‐weight diglycidyl ether of bisphenol A cross‐linked with aliphatic amine. Two anthracites of extremely different structures were compared to natural graphite that is composed of well‐ordered graphene sheets. Systematic studies of the influence of the structure of anthracite filler on the curing behavior, morphology, dynamic mechanical thermal properties, and thermal stability of epoxy composite were performed. It was found that the structure of anthracite filler affects the cross‐linking reactions of the epoxy matrix as well as the morphology of the composites and their viscoelastic properties. Raw anthracite added to epoxy matrix had a visible effect on the activation energy and differential scanning calorimeter parameters of the curing process, in contrast to the epoxy matrix modified with anthracite heated at 2,000°C. On the contrary, the effect of anthracite on dynamic mechanical behavior of composites is more evident when the anthracite prepared at 2,000°C was used as a filler. POLYM.
