  title={Expanded Wood Fiber Polystyrene Composites: Processing–Structure–Mechanical Properties Relationships},
  author={Saeed Doroudiani and Mark Kortschot},
  journal={Journal of Thermoplastic Composite Materials},
  pages={13 - 30}
In this study, processing–structure–mechanical properties relationships in expanded wood fiber polystyrene composites (EPSC) made with a physical blowing agent were investigated. A systematic investigation was performed based on a statistical experimental design. The samples were saturated with carbon dioxide at high pressure and ambient temperature and the saturated specimens were expanded at elevated temperatures. The relations between impact and tensile properties of EPSC and foaming process…

Morphology and properties of polystyrene/agave fiber composites and foams

In this work, agave fibers were blended with polystyrene to produce foamed and unfoamed composites. The effect of fiber size and density reduction on the morphological, thermal, mechanical, and

Manufacture of natural fiber filled polystyrene composites and their microcellular foams.

In this study, lignocellulosic filler (wood flour or wheat straw flour) and polystyrene-block-poly(ethyleneran-butylene)-block-polystyrene-graft-maleic anhydride (SEBS-MA) additive were used to

The potential of wood fibers as reinforcement in cellular biopolymers

Wood fiber-reinforced polylactic acid composite foams have been successfully produced using supercritical carbon dioxide. The addition of fibers had a strong effect on microstructure of the foams. An

The effect of filler addition and coupling agent content on the mechanical properties and morphology of wood plastic composites was examined. Using wood flour as the reinforcement filler and recycled

Comparison of foam core materials in innovative lightweight wood-based panels

In the present paper, lightweight wood-based foam core panels were produced in a novel continuous process. Expandable microspheres (MS) and expandable polystyrene (EPS) were used as core materials.

Effect of wood powder on polymer foam nucleation

It is usually reported that wood particles in wood/polymer composite foams can act as nucleating sites. Since high wood contents are used, it is difficult to determine exactly the effect of wood

Nanotechnology applied to polymer foams is an emerging field. The possibility to add nanofillers to polymers and to expand them by supercritical carbon dioxide represents an important development in

Preparation and morphology of polypropylene/wood flour composite foams via extrusion

In this study, polypropylene (PP)/wood flour composites foams with an average cell size lower than 100 μ were successfully produced by extrusion. The effects of the coupling agent (maleated PP), wood



Polystyrene foams. I. Processing‐structure relationships

In this study, processing-structure relationships in expanded polystyrene (EPS) made using near-critical carbon dioxide as a physical blowing agent were investigated. In order to investigate the

Foaming of PS/wood fiber composites using moisture as a blowing agent

This paper presents an experimental study on foam processing of polystyrene (PS) and high-impact polystyrene HIPS/wood-fiber composites in extrusion using moisture as a blowing agent. Wood-fiber

Polystyrene foams. II. Structure–impact properties relationships

In the first part of this series of articles, the relations between the foaming conditions and the microstructure of expanded polystyrene (EPS) were explored. In this part, the effects of the foaming

Failure Mechanisms in Fibre Reinforced Rigid Polyurethane Foam

The use of foamed plastics as structural materials represents an area of technology which is experiencing rapid growth as both new outlets and replacements for traditional materials appear. Whilst


Abstract In the present paper the emphasis is put on theoretical consideration of the mechanical behavior of short-fiber-reinforced composites. Starting from the concept of microscopic construction

Sorption and diffusion of carbon dioxide in wood‐fiber/polystyrene composites

In this study, sorption and diffusion of carbon dioxide (CO 2 ) in wood-fiber/ polystyrene composites were investigated. The effects of gas pressure and fiber content on the solubility and diffusion
