Tailored Fiber Placement in Thermoplastic Composites

, 2018
Fiber path optimization methods combined with the Tailor Fiber Placement (TFP) technology provide the optimum correlation between load case and fiber orientation and therefore lead to unmatched component performance with endless fiber composite materials.

Saturation of the stress-strain behaviour of architectural fabrics

Materials & Design, 2020
The stress-strain characteristics of nonlinear visco-elastoplastic architectural fabrics show a mechanically saturating behaviour in cyclic tensile tests: stiffness changes decline, the increase of permanent strain decreases and the nonlinear material ...

Al–Cu Composite Casting of Laser‐Deoxidized Copper: Bonding, Interfacial Chemistry, and Thermal Conductivity

Advanced Engineering Materials, EarlyView.
This study investigates laser‐based oxide removal of Cu inserts in oxygen‐free conditions and examines long‐term oxidation kinetics and surface chemistry under different atmospheres via X‐ray photoelectron spectroscopy. Al–Cu compound casting with differently oxidized surfaces is performed, and intermetallic phase formation, morphology, and thermal ...

Structural Lightweight Concrete Containing Recycled Lightweight Concrete Aggregate

KSCE Journal of Civil Engineering, 2018
In this paper, Structural Lightweight Concrete (SLC) containing Recycled Lightweight Aggregate (RLA) is described. Damaged lightweight concrete was used as RLA by crushing it into fine particles, and used to replace fine limestone aggregate of up to 45% by weight.

Ductility and brittleness of lightweight aggregate concrete structures

, 2021
Lightweight aggregate concrete (LWAC) has been used in construction since ancient Greek and Roman times, for more than two thousand years. With its low density, it was mainly used to reduce the weight of the structures.
