“…8 Tensile stiffness may continue to increase with fiber volume fraction; the laminate's compressive strength will reach a peak and then it begins to decrease due to the lack of sufficient resin to arrest the fiber micro-buckling. 9 Test laminates of the subject study were characterized for fiber volume (V f ) and void fraction (V v ) as per ASTM D 3171. Results presented in Table 1 reveal that all the laminates have comparable fiber volume and void fraction.…”

Continuous glass fiber reinforced thermoplastic composites have been manufactured and their mechanical properties have been evaluated. A catalyzed monomer is infused through a stack of compacted dry reinforcement under vacuum. The monomer undergoes radical polymerization with a peroxide catalyst. Viscosity and reactivity profile have been characterized to determine the catalyst concentration and temperature of infusion. Glass fiber reinforced thermoplastic composites realized through this method have mechanical properties that are comparable with that of epoxy with an added advantage of excellent toughness and repairability. For example, the residual compressive strength of thermoplastic composites after low-velocity impact is found to be over 140% more than that of epoxy-based composites using the same reinforcement and realized under identical manufacturing methods.

“…Haddad and Feng [42] further confirmed this tendency. Furthermore, the volume fraction of matrix for damping has been investigated and the results revealed that the damping ratio of three-layer-connected biaxial weft-knitted fabric reinforced composites increased with the increasing of matrix volume fraction [43]. The reason can be attributed to the higher stresses in the matrix due to closer spacing which resulted in higher energy dissipation capacity during the dynamic loading.…”

Fiber reinforced polymer composites have great potential for engineering applications. In this work, we have provided a comprehensive review on the damping properties of fiber reinforced polymer composites. This paper has focused on the mechanism and analytical method of damping properties. This work also presents a broad review on several factors which determined the damping, such as matrix, fiber types, fiber architecture, fiber surface modification, and incorporated fillers. We further discussed the role of interfacial region on the improvement of damping, where high shear strain energy is stored at this region. Nanofillers, fiber coating, and interpenetrating polymer networks have high potential for damping treatment. We have concluded this review with some helpful suggestions for the future development of fiber reinforced composites with desired damping properties.

“…This could include deciding on the types of fiber and matrix to be used for each lamina, the volumetric ratio of the fiber, lamina thickness, orientation of the fiber in the lamina, the periodicity or randomness of the fiber in the microscale structure of the advanced composites, sequence of the laminas in the laminate and the resin used. [17][18][19] The final decision is an output of a complicated interactive process the boundary of which is the anticipated characteristics of the bridge structural systems and their performance under extreme loading conditions. Although following general material and sectional design regulations adopted from experience with traditional cable-stayed bridge systems is supposed to simplify and accelerate the analysis-design procedure, it does not guarantee that the structural system will pass all the limit states and the aerodynamic stability requirements.…”

An innovative solution is proposed in this paper by introducing a hybrid-type cable stayed bridge as a competent system to safely bridge very long spans. The new system leads into huge reduction in deck weight and its critical stresses in the pylon zones by using hybrid advanced composite deck. It also reduces the stiffness losses of the stay-cables due to the catenary's action by using carbon fiber reinforced polymer cables. The paper proposes a proper consistent and systematic analysis and design procedure that optimize and precisely simulate the proposed bridge system. It recognizes the changes in structural behavior of the cable-stayed system, accordingly it clearly defines the ultimate and serviceability limit states for such new structural system in consistence with the limit state design philosophy. The design steps of the ADP represent a multi-scale design technique while the analysis steps characterize a multi-scale modeling technique. They represent the material design in the micro/macro-level, and accurate homogenization of the advanced composite components properties and evaluation of the resulting anisotropic characteristics and then, three-dimensionally simulate the hybrid bridge system involving all its nonlinearities. This paper investigates the performance of a new hybrid long-span cable-stayed bridge, which engages the use of advanced composite materials for the deck and the stay-cables, applying the analysis and design procedure. This design is scaled to match the general geometrical shapes, structural and aerodynamic characteristics of three of the world-longest cable-stayed bridges. What's more, four advanced composite deck section models are proposed in this research. In order to study the performance of the referenced bridges, such as the natural frequencies, the deck top surface maximum vertical displacement, maximum Tsai-Hill failure function and the critical flutter velocity, three sets of parameters are investigated. The parameters include: (i) the micro level parameters-fiber fraction, (ii) the macro level parameters-Laminas Dominant Fiber Alignment and Laminate Thickness and (iii) the structure level parameters-cable radius.
