Properties of Wood Fibre-Polypropylene Composites: Effect of Wood Fibre Source

12-04-2010 | Svetlana Butylina, Ossi Martikka, Timo Kärki, Applied Composite Materials, 2010

This study examined the effect of type of wood fibre source on the physical and mechanical properties of wood fibre-polypropylene composites. Wood flour, fibres of heat-treated wood and pellets were used as sources of wood fibres in the manufacturing process. All studied wood ...

Impact Response Characterization in Composite Plates—Experimental Validation

08-04-2010 | Andreas P. Christoforou, Ahmet S. Yigit, Wesley J. Cantwell, Fanjing Yang, Applied Composite Materials, 2010

This paper presents an experimental study for the normalized low-velocity impact response of composite plates. It is demonstrated that a characterization diagram that shows the relationship of three non-dimensional parameters with the normalized maximum impact force can be used to fully ...

Local Structure Fixation in the Composite Manufacturing Chain

08-04-2010 | Lina Girdauskaite, Sybille Krzywinski, Hartmut Rödel, Andrea Wildasin-Werner, Ralf Böhme, Irene Jansen, Applied Composite Materials, 2010

Compared to metal materials, textile reinforced composites show interesting features, but also higher production costs because of low automation rate in the manufacturing chain at this time. Their applicability is also limited due to quality problems, which restrict the production of complex ...

Finite Element Dynamic Analysis of Laminated Viscoelastic Structures

25-03-2010 | Naser Al-Huniti, Fadi Al-Faqs, Osama Abu Zaid, Applied Composite Materials, 2010

This work is concerned with the dynamic behavior of laminated beam, plate and shell structures consisting of a viscoelastic damping layer constrained between two structural layers. Finite element models for modal, harmonic and transient analyses are developed. The dynamic interlaminar shear ...

Effects of Stitching on Delamination of Satin Weave Carbon-Epoxy Laminates Under Mode I, Mode II and Mixed-Mode I/II Loadings

18-03-2010 | Walid Trabelsi, Laurent Michel, Renaud Othomene, Applied Composite Materials, 2010

The objective of the present study is to characterize the effect of modified chain stitching on the delamination growth under mixed-mode I/II loading conditions. Delamination toughness under mode I is experimentally determined, for unstitched and stitched laminates, by using untabbed and ...

Finite Element Analysis of Mechanical Properties of 3D Four-directional Rectangular Braided Composites—Part 2: Validation of the 3D Finite Element Model

11-03-2010 | Dian-sen Li, Dai-ning Fang, Zi-xing Lu, Zhen-yu Yang, Nan Jiang, Applied Composite Materials, 2010

In the first part of the work, we have established a new parameterized three-dimensional (3D) finite element model (FEM) which precisely simulated the spatial configuration of the braiding yarns and considered the cross-section deformation as well as the surface contact relationship between ...

Finite Element Analysis of Mechanical Properties of 3D Four-Directional Rectangular Braided Composites Part 1: Microgeometry and 3D Finite Element Model

25-02-2010 | Dian-sen Li, Jia-lu Li, Li Chen, Zi-xing Lu, Dai-ning Fang, Applied Composite Materials, 2010

Based on the microstructure of three-dimensional (3D) four-directional rectangular braided composites, a new parameterized 3D finite element model (FEM) is established. This model precisely simulates the spatial configuration of the braiding yarns and considers the cross-section deformation ...

A Quasi-Exact Dynamic Finite Element for Free Vibration Analysis of Sandwich Beams

25-01-2010 | Seyed M. Hashemi, Ernest J. Adique, Applied Composite Materials, 2010

A Dynamic Finite Element (DFE) model for the vibration analysis of three-layered sandwich beams is presented. The governing differential equations of motion of the sandwich beam for the general case, when the properties of each layer are dissimilar, are exploited. Displacement fields are ...
