“…For the RT and 40 °C impacted specimens, the peak load remained nearly constant, which might be because at elevated temperatures, softening or plasticisation of the matrix enhances the impact damage resistance. This phenomenon is associated with the investigation of the impact properties of the jute/UP composites when the impact temperature is higher than the T g , the softening of matrix occurred by the decrease in the percentage of hits corresponding to matrix [28].…”

“…Their results exhibited that the delaminated area increased due to impact and post impact compressive strength as a function of absorbed energy. Moreover, the impact response of the composite laminates has been a major concern in engineering applications because of lack of full understanding of the effect of impact and post impact loadings on the failure mechanisms, low impact damage resistance and low transverse mechanical properties [11,12].…”

The effects of milled glass fibre as fillers on the impact and post impact compression (CAI) behavior of glass/epoxy composite laminates is investigated. The milled glass fiber fillers 5% by weight of epoxy were incorporated into the glass/epoxy laminates by using ultra-sonication and mechanical stirring techniques then the results were compared with the baseline glass/epoxy laminate. The incident energy applied were 10, 15, 20, 25 and 30 Joules. The glass filler loaded samples exhibited higher peak force than the baseline samples. The compression strength of Non-Impacted (NI) filler loaded samples was improved by 18% compared to the baseline samples. A good correlation between milled glass filler addition into the matrix of glass/epoxy composites and the improvement in impact damage and residual CAI behaviors were evident. The improved impact and CAI properties of milled glass filled composite indicate that this composite is a good candidate for load bearing applications.

“…Ever-increasing environmental concerns and shortages of petroleum resources have led to a demand for natural fibers from bamboo (Tran et al 2013), hemp , flax (Bozaci et al 2013), kenaf (Hussein et al 2013), sisal (Prasad and Rao 2011), and jute (Dhakal et al 2014) to replace conventional glass-and petroleum-based fibers as reinforcements in UPE-based composites.…”

Mechanical and Thermal Properties of Hemp Fiber-Unsaturated Polyester Composites Toughened by Butyl Methacrylate

et al. 2015

Hemp fiber-reinforced unsaturated polyester (UPE) composites were prepared by hand lay-up compression molding. The UPE resins were modified with butyl methacrylate (BMA) to improve the flexibility and toughness of the hemp-UPE composites. The results indicate that the toughness of the composites significantly increased as BMA usage increased. Compared to the unmodified UPE composites, the composites obtained from BMA-modified UPE resins had 27.4, 63.0, and 36.6% greater elongation at break, flexural strain, and impact strength, respectively. The optimum BMA usage to achieve an adequate balance of stiffness and toughness is 20 to 30%. Dynamic mechanical analysis (DMA) indicated that incorporation of BMA significantly decreased the storage modulus and glass transition temperature of the composites and increased its damping parameter due to the introduction of flexible segments into the UPE resins. Thermogravimetric analysis showed that the thermal stability of the composites decreased slightly following the incorporation of BMA. Scanning electron microscopy images of the impact-fractured surfaces of the composites revealed that BMA incorporation improved interfacial adhesion between hemp fibers and UPE matrices and that the main mechanism for the increase in the toughness of the composites was the added ductility of the matrices.
