“…Similar improvements in carbon/glass hybrids were found for penetration impact resistance by Onal and Adanur [103]. Sevkat et al [102] reported that the damaged area in their carbon/glass fibre hybrids was higher than in both reference composites. This was attributed to a greater susceptibility to delaminations due to the incompatibility of the layers.…”

Fibre-reinforced composites are rapidly gaining market share in structural applications, but further growth is limited by their lack of toughness. Fibre hybridisation is a promising strategy to toughen composite materials. By combining two or more fibre types, these hybrid composites offer a better balance in mechanical properties than non-hybrid composites. Predicting their mechanical properties is challenging due to the synergistic effects between both fibres. This review aims to explain basic mechanisms of these hybrid effects and describes the state-of-the-art models to predict them. An overview of the tensile, flexural, impact and fatigue properties of hybrid composites is presented to aid in optimal design of hybrid composites. Finally, some current trends in fibre hybridisation, such as pseudoductility, are described.

“…Enfedaque et al [101] and Sevkat et al [102] found that symmetric carbon/glass hybrids had a better penetration impact resistance if the glass was put on the outside rather than on the inside. Both authors attributed this to the higher failure strain of the glass fibres, which delays the onset of damage.…”

“…Second, there is no rebound when most of the energy is absorbed by the composite through various modes of damage. Finally, under a high level of impact energy, obvious damage can be observed on the composite panel (Sevkat et al 2009). As shown in Fig.…”

Compressed lumber is considered to be a superior structural material due to its uniform properties and higher strength than other solid timbers. This study presents the effect of steaming on some properties of compressed lumber of oil palm (Elaeis guineensis) trunks (OPT). The specimens were steamed at a temperature of 130 ⁰ C for 2 hours before being compressed in a hot press and evaluated for their physical and mechanical properties. Compressed OPT without steaming was used as a comparison sample to compare the effect of steaming on compressed OPT. The average modulus of rupture of steamed compressed OPT samples was 31.36 MPa, which was 8.7% higher than the compressed OPT without steaming samples. The modulus of elasticity was determined to be 8919 MPa, 9.9% higher than the compressed OPT samples. Steaming enhanced the dimensional properties of the samples. Thickness swelling and water absorption of the steamed compressed OPT samples were 6.57% and 33.84%, respectively, lower than those of the samples without steaming. Some other properties such as compression strength, dynamic bending strength, and the compression and recovery ratios were also evaluated. Scanning electron micrographs taken from the cross section of the samples showed a clear difference between the compressed and uncompressed oil palm.

“…Sevkat et al (2009b) adopted a nonlinear orthotropic damage model to study damage in composite beams subjected to ballistic impacts with the instantaneous stiffness-degradation scheme (described in Section 2.2). In addition, LS-DYNA with a Chang-Chang linear-orthotropic damage model was used for comparison.…”

Composites reinforced with woven or braided textiles exhibit high structural stability and excellent damage tolerance thanks to yarn interlacing. With their high stiffness-to-weight and strength-to-weight ratios, braided composites are attractive for aerospace and automotive components as well as sports protective equipment. In these potential applications, components are typically subjected to multi-directional static, impact and fatigue loadings. To enhance material analysis and design for such applications, understanding mechanical behaviour of braided composites and development of predictive capabilities becomes crucial. Significant progress has been made in recent years in development of new modelling techniques allowing elucidation of static and dynamic responses of braided composites. However, because of their unique interlacing geometric structure and complicated failure modes, prediction of damage initiation and its evolution in components is still a challenge. Therefore, a comprehensive literature analysis is presented in this work focused on a review of the state-of-the-art progressive damage analysis of braided composites with finite-element simulations. Recently models employed in the studies on mechanical behaviour, impact response and fatigue analyses of braided composites are presented systematically. This review highlights the importance, advantages and limitations of as-applied failure criteria and damage evolution laws for yarns and composite unit cells. In addition, this work provides a good reference for future research on FE simulations of braided composites.
