In this work, a simple but effective approach was reported for preparing natural fiber reinforced plastic foams based on plant oil with excellent compressive performance and biodegradability. Firstly, epoxidized soybean oil (ESO) was converted into its acrylate ester AESO, which can be free-radically copolymerized with reactive diluents like styrene to give thermosetting resins and their foam plastics. Then the bio-foam composites were produced using short sisal fiber as the reinforcement. Effects of fiber loading, length and surface treatment on properties of the foam composites were investig

Rigid low-density plastic foams subjected to mechanical loads typically exhibit a nonlinear deformation stage preceding failure. At moderate strains, when the geometrical nonlinearity is negligible, such foam response is predominantly caused by the nonlinearity of deformation of their principal structural elements—foam struts. Orientational averaging of stresses in foam struts enables estimation of the stresses taken up by foams at a given applied strain. Based on a structural model of highly porous anisotropic cellular plastics filled with clay nanoplatelets and the orientational averaging, a

PLA is a bio-based biodegradable plastic, which has excellent biocompatibility and biodegradability. Because the mechanical properties of microcellular foaming material is similar to petroleum-based plastics (PS), PLA foams have been considered as ideal alternative materials. However, PLA has several inherent drawbacks such as low melt strength and slow crystallization kinetics, which severely inhibit the PLA foaming process to produce high-density forms and uniform cell morphology.

The evolution of a bidimensional foam submitted to continuous quasi-static shearing isinvestigated both experimentally and numerically. We extract, from the images of the sheared foam, the plastic flow profiles as well as the local statistical properties of the stress field. When the imposed strain becomes larger than the yield strain, the plastic events develop large spatial and temporal correlations, and the plastic flow becomes confined to a narrow shear band. This transition and the steady-state regime of flow are investigated by first focusing on the elastic deformation produced by an ele

When increasing the wood fiber (WF) content in extruded wood fiber/plastic composites (WPC) foams, a good balance between reducing the cost and obtaining good cell morphology should be maintained. This study examines the relationship between WF content and the foam morphology in WPC foams. The role of WF as cell nucleating agent at low concentrations (10 wt.%) was observed, as WPC foam with 10 wt.% WF had lower average cell size and higher cell density than neat HDPE foams. Increasing the WF content further, decreased the average cell size and cell density, and increased the foam density of WP

Single-use plastic foams are used extensively as interior packaging to insulate and protect items during shipment but have come under increasing scrutiny due to the volume sent to landfills and their negative impact on the environment. Insulative compression molded cellulose fiber foams could be a viable alternative, but they do not have the mechanical strength of plastic foams. To address this issue, a novel approach was used that combined the insulative properties of cellulose fiber foams, a binder (starch), and three different reinforcing paperboard elements (angular, cylindrical, and grid)

Metal foams are two-phase compounds of a gas and a solid with several interesting physical and mechanical properties; in particular they have very low density, good rigidity, excellent energy absorption, high vibration damping. At now, the final shape of foamed devices is directly obtained through the foaming process itself and no further shaping steps are expected. Anyway, the plastic formability of metal foams, in order to both characterize the material itself and to produce more complex parts, seems to be useful for several industrial applications.

Within this framework, an analytical expression of the Hugoniot stress-strain curve is proposed for elastic-plastic cellular materials. The predictions derived from the proposed model are in excellent agreement with experimental data for open-cell aluminium foams. The case of viscoplastic foams is also considered.

The objective of this work is to numerically investigate the elastic–plastic deformation of closed-cell foams incorporating the effect of inner gas pressure. Both body-centered cubic (BCC) and face-centered cubic (FCC) arrangements of pores are considered in analysis. It is seen that the inner gas pressure has a significant effect on the plastic deformation of closed-cell foams, which is different for the foams with different microstructures and is discussed in detail. The inner gas pressure results in the asymmetry of uniaxial tensile-compressive stress–strain curves and the nominal Poisson's

The dynamic compressive behavior of open-cell aluminum alloy foams with different length of specimens was investigated using the split Hopkinson pressure bar technique. Plastic strength was measured for aluminum alloy foam specimens having the three cell sizes but similar cell microstructure. Longer specimens exhibited lower mean strength and broader scattering of the strength values than the shorter ones. It can be observed that mechanical response of aluminum alloy foams appear to be dependent of the cell size for both the shorter and longer specimens.

Previous studies have shown that structural properties of the hull composite are largely dependent on the physical properties of the foam core material and therefore thermally induced foam degradation could seriously impair the structural integrity of the vessel. Consideration of the Australian climate, and in particular that of the tropical North, led to evaluations of the temperature dependence of core properties. Results of

AbstractThe introduction of metal foams into the building market represents a significant opportunity to increase the use of metal in construction. Developing new structural products made of metal foams and steel could improve conventional buildings' performances in terms of stiffness and resistance. Steel or aluminium foams are characterised by mechanical properties similar to glulam timber, combined with a high energy dissipation capacity. These peculiarities allow conceiving new composites with features typical of the bio‐mimetic materials: lightness, compactness, dissipation, resistance an

Many efforts have been made recently to determine the fracture toughness of different types of foams in static and dynamic loading conditions. Taking into account that there is no standard method for the experimental determination of the fracture toughness of plastic foams, different procedures and specimens were used. This paper presents the polyurethane foam fracture toughness results obtained experimentally for three foam densities. Asymmetric four-point bending specimens were used for determining fracture toughness in mode I and in a mixed one, and also the influence of the loading speed a

Plastic foam is widely used in varying industries due to its light weight, high strength, and good heat insulation. However, most plastic foams are produced from petroleum-based polymers which cannot be naturally degraded and can release aromatic pollution to the environment when they are molten or burned. Therefore, poly(butylene succinate) (PBS) and KMnO4-treated spent coffee grounds (SCG), which are biopolymer and bio-filler, are used to prepare the bio-composite foam in this research by using azodicarbonamide (ACDA) as a chemical blowing agent. The 10, 20, and 30 phr of the treated SCG and

In this work, plastic foams were prepared from plant oil resins based on soybean oil and castor oil. Firstly, epoxidized soybean oil (ESO) reacted with acrylic acid using N, N-dimethyl benzyl amine as the catalyst, and castor oil was modified with maleic anhydride, respectively. Acid number was used to monitor the reaction process, and structures of the resultant acrylated epoxidized soybean oil (AESO) and maleate castor oil (MACO) were proved by Fourier Transform Infrared (FTIR) measurements. It was found that the catalyst is quite effective in synthesizing AESO. Then, plastic foams based on
