Composite materials and, in particular, Carbon Fibre Reinforced Polymers (CFRP) have been well studied and developed in the past years due to their advanced mechanical characteristics. These materials are used in several different application fields, such ...
Layered fiber reinforced composite materials are prone to fracture in planes parallel to the direction of fibers leading to extensive delamination or intralaminar fracture. This phenomenon of crack propagation is frequently accompanied by significant incre ...
A concept of a nature-inspired pedestrian bridge which tries to merge architectural, structural and manufacturing aspects in an optimized way is presented. The 18.0-m-span bridge is designed as an overhead spatial frame of a complex double-curved shape, wh ...
The fouling of neurotransmitter during electrochemical detection can dramatically jeopardize the viability of the sensor. Several recent developments in electrode fabrication and design have helped mitigating this issue. For instance, carbon nanotube fiber ...
Delamination propagation in fibrous laminates is often accompanied by development of a damage zone, within which intact fibers bridge the crack faces that constitutes a major toughening mechanism. A direct experimental assessment of the crack closure tract ...
Thermoplastic polymer composites (TPC) with multiple fabric layers of continuous fiber reinforcement are laminate sheets designed to be thermally stamped and overmolded leading to low cycle times and thus high volume composite parts. Injection over-molding ...
To strengthen a reinforced concrete (RC) slab with deficient shear resistance, it is proposed to add to the top of the slab a 25-50 mm thick layer of ultra-high performance fibre reinforced cement-based composite (UHPFRC) with small diameter rebars (R-UHPF ...
There is a growing interest in exploring novel material combinations and processing technology to manufacture complex 3D shaped polymer and composite structures. In the field of prosthetics and orthotics, this need is significant with additional challenges ...
A cohesive zone model (CZM) is proposed to assess the thickness scaling effect associated with fiber bridging during fracture. The CZM was developed through a multi-scale simulation approach and utilizes an embedded cell model of the Double Cantilever Beam ...
In this work, the influence of ply thickness on strain energy release rate (ERR) in delamination of carbon epoxy laminates is addressed. Specimens with three ply thicknesses: 0.030, 0.075 and 0.150 mm are tested. While the ERR at onset of crack propagation ...
