Effect of Glass Fiber Hybridization on the Behavior Under Impact of Woven Carbon Fiber/Epoxy Laminates [PDF]

, 2010
The low-velocity impact behavior was studied in hybrid laminates manufactured by RTM with woven carbon and glass (S2) fabrics. Specimens with different thicknesses and glass fiber content (from 0 to 21 vol.%) were tested with impact energies in the range

Discussion on Road Reflection Crack and Control

IOP Conference Series: Materials Science and Engineering, 2020
Abstract This paper focused on the problems encountered in the road construction of a coal-fired power plant in the Philippines as an example. Some cracks and damage appeared in the roadbed after the road concrete base layer has been built.

Review of reflective cracking in composite pavements

International Journal of Pavement Research and Technology, 2020
Reflective cracking is identified as the main weakness of composite pavement in airfield and highways forcing the authorities to devote a large portion of their budget to rehabilitation and/or reconstruction of the existing composite pavements. It is, therefore, very important to have a better understanding of the reflective cracking mechanism to ...

Digital light processing and electromagnetic wave absorption performance tuning of SiOC/SiO2 ceramics

Journal of Materials Research and Technology, 2023
SiOC ceramics have been applied to the fabrication of electromagnetic wave (EMW) absorbing metastructures by stereolithography and demonstrate excellent absorptivity due to the designability of the macrostructure. However, the pyrolysis of photosensitive

Duplex Stainless Steel Laser‐Surface Textured: Stability in Brine Solution

Advanced Engineering Materials, EarlyView.
Controlled laser‐surface treatment (LST) of duplex DSS2205 steel is performed to increase its stability in brine solution under cyclic electrochemical assays. The superior protection with respect to flat and smooth panels is attributed to the presence of FeCr2O4 as the main protective oxide layer in the LST surface, after corrosion tests. The stability

Impact of cement content in cement bound materials on the reflection cracking performance of asphalt pavements

Case Studies in Construction Materials
This study investigates the impact of cement contents in cement bound material (CBM) on asphalt pavement reflection cracking, considering two levels: 4.5 % (CBM1) and 5.4 % (CBM2). Mechanical properties of CBMs, including elastic modulus, rupture modulus,

Surface-Functionalized Nanocelluloses as Viscosity-Modifying Agents in Engineered Cementitious Composites

Frontiers in Materials, 2021
This study investigated the feasibility of using nanofibrilliated celluloses (CNF) (0.1% by weight of binder materials) with three oxidation degrees, no oxidation (NCNF), low oxidation (LCNF), and high oxidation (HCNF), as a viscosity-modifying agent ...

Scanning laser source and scanning laser detection techniques for different surface crack geometries [PDF]

, 2012
Standard test samples typically contain simulated defects such as slots machined normal to the surface. However, real defects will not always propagate in this manner; for example, rolling contact fatigue on rails propagates at around 25º to the surface,

Specular Reflection by Contacting Crack Faces

, 1984
Non-linear relations are postulated between the transmitted tractions and the crack opening displacements across contacting rough crack faces. For the opening mode these relations take into account that a crack easily opens, but that the resistance to crack closure increases rapidly as the rough crack faces come in contact.

Influence of Sample Preparation and Processing Procedures on the Thermal Diffusivity of MgO‐C Refractories

Advanced Engineering Materials, EarlyView.
The thermal diffusivity of MgO‐C refractories is highly sensitive to sample preparation and processing procedures. In this article, the effects of coking sequence, machining conditions, structural inhomogeneity, and graphite coating application on measurements using laser flash apparatus are systematically investigated.
