“…However, epoxy resins are inherently brittle, which makes them vulnerable to micro-cracks produced in service, and this lack limits their applications. Extensive studies have been conducted to toughen epoxy resins using liquid rubbers [12][13][14][15]. Recently, the incorporation of low molecular weight liquid rubbers into epoxy/clay nanocomposite, to generate a new kind of polymeric material with remarkable properties [16][17][18][19][20], has been considered.…”

Liquid-rubber-modified epoxy/clay nanocomposites: effect of dispersion methods on morphology and ultimate properties

Epoxy/clay nanocomposites modified with carboxyl-terminated poly (butadiene-co-acrylonitrile) (CTBN) liquid rubber (epoxy/clay/CTBN nanocomposites) are synthesized using two different pre-mixing techniques: mechanical high shear mixer (homogenizer) and ultrasonication using tip sonicator. The observations suggest that low molecular weight CTBN easily diffuses into clay galleries, thereby increasing the d-spacing in epoxy/clay/CTBN nanocomposites, regardless of premixing method. High shear mixing causes breaking of clay platelets in epoxy/clay/ CTBN nanocomposites, leading to a reduction in the aspect ratio. Epoxy/clay/CTBN nanocomposites prepared via sonication have achieved a uniform and stable morphology, in which the clay platelets are dispersed in epoxy matrix in such a way that most of them try to localize near the phase-separated CTBN domains. Thermal and mechanical properties of the resulting nanocomposites are correlated with morphological findings.

“…However, so far no studies have been performed to establish unambiguously the nano-scale structure of these networks. Several other works in the literature report the use of polybutadiene functionalized with hydroxyl [50][51][52][53][54][55], epoxide [56][57][58][59], carboxyl [49,[60][61][62], and amine [63,64] as modifiers for the epoxy matrix, but all systems presented phase-separated morphology in the cured state because of the great incompatibility between polybutadiene and the epoxy matrix. In this sense, it appeared us that the confirmation of the totally nanoscopic character of the structure of the blends prepared by using PBNCO would be an interesting contribution for future development of technical applications.…”

“…Many researchers have been conducted to increase the toughness such as by using glass beads, alumina trihydrate and silica. The most successful works, involving the addition of a suitable rubber such as liquid amineterminated (ATBN) [8], carboxyl-terminated (CTBN) [9][10][11][12] and hydroxylterminated (HTBN) [13][14][15]. Thomas et al [10] has been reported the use of epoxy-terminated (ETBN) copolymers of butadiene while Saadati et al [8] has worked out using hydroxyl-terminated and epoxy-terminated polybutadiene to interpenetrating the polymer networks (IPN) structures.…”

Effects of liquid epoxidized natural rubber (LENR) on the mechanical behaviour of kenaf fibre reinforced epoxy composite were studied. Kenaf fibres (Hibiscus cannabinus, L. family Malvaceae) and thermoset matrices were hand-laid up and characterized in terms of its mechanical properties. The objective of this research is to investigate the effect of LENR to the flexural and impact properties of the kenaf fibre reinforced epoxy composites. The fibres were alkali treated before use as reinforcement in the epoxy resin matrix. Five different fibre concentrations of 5%, 10%, 15%, 20% and 25% by weight have been used (with and without addition of liquid epoxidized natural rubber). Flexural, impact and DMTA tests of rubber toughened epoxy reinforced kenaf fibre composites were performed. The fractured surfaces of these composites were investigated by using scanning electron microscopic technique (SEM) to determine the interfacial bonding between the matrix and the fibre reinforcement. It was found that the addition of LENR increased the flexural strength, flexural modulus and impact strength by 17.6%, 11% and 47% respectively.
