Thermal behaviour and dynamic mechanical analysis of Pennisetum purpureum/glass-reinforced epoxy hybrid composites

Dynamic Mechanical Analysis of Treated and Untreated Sugar Palm Fibre-based Phenolic Composites

“…This could have led to better fibre-matrix bonding and an increased storage modulus for the composites; it is a reasonable explanation for the high values of the storage modulus of the treated composites and is in agreement with other studies (Leman et al 2008;Ishak et al 2013). Ridzuan et al (2016) found that the alkaline treatment of Pennisetum purpureum/glass-reinforced epoxy composites led to higher Eʹ values compared with composites formed with untreated fibres.…”

“…This gives credence to the effect of the treatment on the fibrematrix interfacial bonding. The damping properties of heterogeneous materials depend on certain factors, for example, breakage or bonding of fibres, matrix cracking, and holes caused by fibre pull-out (Ridzuan et al 2016). A Cole-Cole plot is an effective and powerful tool to evaluate the relationship between the dynamic modulus (Eʹ) and dynamic loss modulus.…”

“…There are many factors that influence the damping factor of polymer composites, such as fibre breakage, fibre-matrix interlocking, matrix cracking, interphase zone, and frictional resistance (Ridzuan et al 2016). In the current study, there was no notable change in the damping factor for any of the composites in the glassy region.…”

“…However, they have certain drawbacks, including poor fibre-matrix interfacial bonding, high moisture absorption, and low thermal stability. Natural fibres, such as kenaf, oil palm, jute, and sisal, are widely used in various polymer composite applications, such as in the automobile industry, building materials, and food packaging (Ridzuan et al 2016;Rashid et al 2017b).…”

Stress analysis of multi-layered hybrid composite pipes subjected to internal pressure

“…A finite element model was developed to understand the deformation and failure mechanisms of a multilayered elastomer/fiber-reinforced polymer (FRP) composite panel under blast. Ridzuan et al [13] were investigated the thermal behavior and dynamic mechanical analysis of Pennisetumpurpureum/glass-reinforced hybrid composites. Pennisetumpurpureum fibers were respectively determined at 64, 64, 67, and 63 0 C, by dynamic mechanical analysis (DMA).…”
