“…Reinforcing of the rGFRP not only increased ILSS, but reduces the sudden failure of composites. This finding agreed with studied done by Fan et al (2008) on enhancement of glass fiber reinforced multi-wall carbon nanotubes and Da Silva et al (2012) studied on hybrid curaua/glass and sisal/glass composites. …”

Delamination known as the failure at the interface between different layers is one of critical failure mechanism for laminates composites. Hybrid laminate composites comprised of unique ply material and structure, unwanted interlaminar shear stresses may occur between ply laminate due to different material behavior and properties. The aim of this research is to study structural integrity effect of interleaf glass mat and recycled GFRP waste (rGFRP) in woven kenaf reinforcement polyester composite. The properties of composites on ILSS and flexural behavior subjected to bending load were measured by flexural and short beam test (SBT). Span length to thickness ratio varies for both tests are 16:1 and 4:1 for flexural test and SBT respectively. Compression molding method was selected for composite fabrication; the fiber weight percentage ratios are constant at 35% of all samples. Results revealed that the flexural stress and flexural shear measured by flexural test is comparable for kenaf and kenaf/glass composites however, kenaf/rGFRP shows significant improvement, increased in maximum flexural stress up to 47.5%. Interlaminar Shear Strength (ILSS) calculated from SBT shows comparable value for all samples with slightly increased about 10% for both hybrid composites. Failure analysis observed by Scanning Electron Microscopic (SEM) and Optical Microscope shows severe interlaminar shear failure occur on glass mat hybrid composites for both tests. From the results, it can be conclude that hybridization of glass mat and rGFRP particulate improved flexural and ILSS properties. It also can be concluded rGFRP is potential to replace glass fiber as reinforcement.

“…As a result, various empirical and mechanisms-based models that predict the temperature-dependent properties of composites have been developed, which are generally functions of either mass (or density) and/or temperature [7,[10][11][12][13][14]. Nevertheless, Correia et al [5] stated that additional experimental data are needed to validate previous results and that further research works are needed regarding the other important properties of pultruded composites profiles, particularly the shear modulus, the elastic modulus in the transverse direction and the interlaminar shear strength (ILSS), which is the limiting design characteristic for pultruded FRP [15]. In addition to these properties, the flexural/bending behaviour at elevated temperatures is also of equal importance as input for modelling and design purposes.…”

A comparative study was conducted to evaluate the temperature-sensitive mechanical properties of glass fibre reinforced polymer (GFRP) composites in the longitudinal and transverse directions. GFRP coupons with different shear span-to-depth ratios were tested under three-point static bending test at temperatures ranging from room temperature up to 200 o C. Timoshenko Beam Theory-based procedure was then adopted to calculate the flexural and shear moduli of the GFRP laminates under moderate and elevated in-service temperatures.The results showed that the mechanical properties of the transversely cut specimens is affected more by the increase in temperature than the longitudinally cut specimens. Similarly, the interlaminar shear and flexural strengths of GFRP composites were found influenced more by elevated temperature compared to the stiffness properties. Moreover, the shear modulus undergone more severe degradation compared to the flexural modulus. Simplified empirical models were proposed to estimate the mechanical properties of the GFRP pultruded laminates in both the longitudinal and transverse directions at varying temperatures.

“…Gojny et al [11] in 2005 improved the ILSS by addition of 0.3wt% DWCNTS. Z Fan et al [12] concluded that by adding up to 2wt% of OWCNT in GFRP laminate, 33% improvement in ILSS is possible. Macro modifiers like short carbon fiber fillers (SCFF) has also been considered as economical fillers to enhance ILSS of GFRP.…”

Abstract. Carbon fillers like carbon nanotubes, short carbon fibers, carbon black and graphene are considered to be highly potential fillers (from macro to nanoscale) to improve mechanical characteristics of polymer matrix composites. In this work, three different samples of glass fiber reinforced composite laminates (GFRP) were prepared (1) neat GFRP, (2) MWCNT reinforced GFRP composite and (3) MWCNT with short-carbon fiber fillers (SCFF) or hybrid reinforced GFRP and tested for short beam strength (SBS). The SBS tests were performed on Hounsfield H50KS universal testing machine (UTM) at a strain rate of 0.05 mm/min. The fabrication of eight layered symmetrical glass/epoxy laminate was done by using press molding machine at 200 KN load. The results justified the significance of MWCNTs reinforcement and hybrid reinforced GFRP over neat GFRP specimen.
