This paper presents an extensive experimental and numerical study on the behavior of CFRP/Steel adhesively bonded double strap joints (DSJ). A total of 50 DSJ specimens were tested under static tensile loading. The digital image correlation (DIC) was used to measure the backface deformation. A total of six adhesives that feature different stiffness...
The continuous increase of structural composite applications urges the need for a profound understanding of the behaviour of mechanically fastened joints in lightweight composite materials. As opposed to adhesive bonding, mechanical fasteners come with easy installation and disassembly processes. However, mechanical fasteners are inherent stress ra...
Laser satellite communication offers new opportunities in global data transfer, and can provide crucial infrastructure to facilitate the ever-growing demand. Creating an optical link of 10.000 km in length requires a telescope with extreme thermal stability, in an environment where thermal loading is periodical as a result of the satellite’s orbit....

The paper reports the analytical investigation in Multi-storey building located in seismic zone III. This zone is considered as moderate-damage risk zone as per Indian Codal provision and thirty percent of India falls in this category. To improve the seismic performance, externally bonded FRP strengthening techniques are adopted to deficient beam a...

In this research work, different combinations of normal strength concrete (NSC), ultra-high-performance concrete (UHPC), and steel fiber-reinforced UHPC (SFR-UHPC) concrete with re-bars of conventional steel and of carbon fiber-reinforced polymer (C-FRP) are used in a two-way square slab of size 1000mm x 1000mm x 75mm subjected to 2500 mm free-fall...
In recent decades, fibre-reinforced polymer composite structures have seen increased aerospace applications. A typical composite structural element widely used in primary load-bearing aircraft components is the T-joint, which is formed when two orthogonal laminates are joined in a T-shaped arrangement to enable out-of-plane load transfer. Under ten...

Damage detection is vitally important for carbon fiber reinforced polymer (CFRP) laminates. When CFRP laminates are damaged, its impedance property is changed. Based on the electrical properties of CFRP laminates, the changed conductivity distribution can be reconstructed with the electrical impedance tomography (EIT) method. The detection method i...
The paper presents tribological tests of selected materials used as liners in a composite hydraulic cylinder. Three coating materials were used for the analysis: Sika F180 polyurethane, Huntsman Araldite LY1564 with Aradur 3487 amine hardener and Bezlona 1111 Super Metal. In addition, uncoated carbon epoxy laminate (CFRP) samples were used as refer...
The increasing use of carbon fiber and epoxy resin composite materials yields an increase in the amount of waste. Therefore, we present a solution consisting of composites manufactured by hot pressing, employing polyamides (either PA11 or PA12) and a mechanically recycled carbon fiber-reinforced polymer (CFRP) as reinforcement. The main objectives ...
