The brittle-to-ductile transition in tensile and impact behavior of hybrid carbon fibre/self-reinforced polypropylene composites Vrije Universiteit Brussel KU Leuven
Hybrid composites combining two fibre types with distinctly different mechanical properties have the potential to surpass the stiffness-toughness dilemma, which is characteristic to standard (single fibre type) composite materials. The current work demonstrates this potential on the example of carbon fibre/self-reinforced polypropylene (SRPP) hybrids. The aim is to understand the transition from brittle to ductile behaviour under tensile and ...
Determination of material parameters of textile reinforced cementitious composite exposed to high temperatures using an inverse method Universiteit Antwerpen
Eliminating the volume redundancy of embedded elements and yarn interpenetrations in meso-finite element modelling of textile composites KU Leuven
© 2015 Elsevier Ltd. All rights reserved. Embedded elements (EE) present a potential for an effective solution of interpenetration of yarn volumes, excluding the need for creation of continuous meshes in the matrix and in the reinforcement. The paper investigates application of contact algorithm to eliminate the interpenetration and introduces a stiffness correction in volumes made redundant because of coincidence of the embedded and the host ...
Fatigue damage evolution in 3D textile composites KU Leuven
© 2015 Elsevier Ltd All rights reserved. The broad range of applications of 3D textile reinforced composites requires an in-depth knowledge of their mechanical properties. Among those, the fatigue behaviour receives high demand in several industrial applications. In this chapter, some experimental investigations are summarized to assess the influence of the three-dimensional architecture of the preform on the fatigue properties and fatigue ...
Fatigue of Textile Composites KU Leuven
© 2015 Elsevier Ltd. All rights reserved. Fatigue of Textile Composites provides a current, state-of-art review on recent investigations on the fatigue behavior of composite materials, mainly those reinforced with textiles. As this particular group of composite materials is extremely important for a wide variety of industrial applications, including automotive, aeronautical, and marine, etc., mainly due to their peculiarities and advantages with ...
Damage accumulation in textile composites KU Leuven
© 2016 Elsevier Ltd. All rights reserved. This chapter introduces typical features of damage development in textile composites loaded in quasi-static tensile tests. It highlights similarities and differences in the damage process between textile and unidirectional cross-ply composites. Textile composites possess some distinct damage patterns that are not found in cross-ply laminates. These are attributed to the special geometrical features of ...
Monitoring of acoustic emission damage during tensile loading of 3D woven carbon/epoxy composites KU Leuven
Registration of acoustic emission (AE) events during tensile loading of fiber-reinforced composites allows the damage caused by these events to be defined and monitored, including damage initiation and progression thresholds. It also provides frequency-based recognition of different types of damage and comparison of its intensity in materials with different reinforcement architectures. The paper reports results of AE registration for 3D ...
Flexible formwork as reinforcement for curved concrete structures Vrije Universiteit Brussel
This paper presents the structural analysis of a stay-in-place formwork in textile reinforced cement (TRC) composites for concrete shells. The purpose of this analysis is to examine with finite element software if the formwork can contribute to the structural performance of a concrete shell and how much TRC is needed to replace the traditional steel reinforcement. This research is part of a broader feasibility study that evaluates the potential ...
Development and experimental validation of a lightweight Stay-in-Place composite formwork for concrete beams. Vrije Universiteit Brussel
Context: Current formwork research aims towards new cost-competitive formwork systems and
materials that focus on labour reduction and efficient material use. This labour cost is reduced when
using Stay-in-Place (SiP) formworks. Besides its forming function, SiP formwork can moreover have a
protective, an aesthetic or even a structural contribution to the hardened concrete element.
Objective: Using cement composites, ...
