“…This synergistic effect can be seen vividly from S4 and S5 laminates (Figure 7d,e). Similar observations were reported by Rasana et al [27] that higher nano filler loading (CNT) declined in the storage modulus of glass fiber reinforced epoxy composites.…”

“…Similar observations were found while hybridizing glass/bamboo and glass/sugar palm fiber-based composites [25,26]. Rasana et al [27] enhanced the thermal stability of glass fiber composites using MWCNT (multi-walled carbon nanotubes). Mourad et al [28] also utilized different nano fillers and improved the thermal stability of Kevlar fiber-reinforced epoxy composites.…”

“…However, at 0.75 wt.% of GNP (S1G3, S2G3, S3G3) there was not much improvement of storage modulus observed for S1, S2 and S3 laminates. From Figure 7d,e it was found that inclusion of GNP up to 0.5 wt.% (S4G2, S5G2) enhanced the storage modulus due to the reduction in polymeric chain movement because of stiffening effect [27]. Also, it is attributed to the fact that nano filler-modified epoxy matrix improved the stress transfer rate from matrix to the reinforcement [27,36].…”

The aim of the present research work is to enhance the thermal and dynamic mechanical properties of Kevlar/Cocos nucifera sheath (CS)/epoxy composites with graphene nano platelets (GNP). Laminates were fabricated through the hand lay-up method followed by hot pressing. GNP at different wt.% (0.25, 0.5, and 0.75) were incorporated with epoxy resin through ultra-sonication. Kevlar/CS composites with different weight ratios (100/0, 75/25, 50/50, 25/75, 0/100) were fabricated while maintaining a fiber/matrix weight ratio at 45/55. Thermal degradation and viscoelastic properties were evaluated using thermogravimetric analysys (TGA), differential scanning calorimetric (DSC) analysis, and a dynamic mechanical analyser (DMA). The obtained results revealed that Kevlar/CS (25/75) hybrid composites at 0.75 wt.% of GNP exhibited similar thermal stability compared to Kevlar/epoxy (100/0) composites at 0 wt.% of GNP. It has been corroborated with DSC observation that GNP act as a thermal barrier. However, DMA results showed that the Kevlar/CS (50/50) hybrid composites at 0.75 wt.% of GNP exhibited almost equal viscoelastic properties compared to Kevlar/epoxy (100/0) composites at 0 wt.% GNP due to effective crosslinking, which improves the stress transfer rate. Hence, this research proved that Kevlar can be efficiently (50%) replaced with CS at an optimal GNP loading for structural applications.

Impact of melamine and its derivatives on the properties of poly(vinyl acetate)-based composite wood adhesive

et al. 2020

A fire retardant composite adhesive for bonding wood and wood-based elements has been developed and characterized. To obtain the enhanced fire-proof properties of the wood adhesive dispersion based on the poly(vinyl acetate) (PVAc), ceramic fillers (17.5 wt% total)—alumina, silica, kaolin and glass fibers were applied. Moreover, fire retardants such as melamine, melamine phosphate and melamine polyphosphate (up to 7 wt%) were also used. Thermal analysis (TG-DSC), strength tests, rheology, pH and flammability measurements (PCFC) were performed. The best properties of the adhesive were achieved for ceramic additives supported by melamine phosphate. A slight improvement of shear strength, shift of the last decomposition step of PVAc (residue degradation) towards higher temperatures by about 50 °C, reduction in mass loss from 100 wt% to less than 70 wt% and about 30–40% improvement of flammability parameters such as heat release capacity, total heat release or peak heat release rate were found compared to the pure poly(vinyl acetate) adhesive.
