The mechanical properties of newly developed aspen fiber–polypropylene composites (APC) were experimentally explored and numerically predicted at the temperatures and humidity that are typical for domestic housing applications. The mechanical properties of APCs with five different fiber-loadings were evaluated at the room temperature, 4 �C, and 40 �C. Environmental effects on the mechanical pro...

In order to investigate the mechanical properties of particulate reinforced polyethylene when using rotational moulding process, different mathematical models are used to predict the tensile properties. A series of micro-sized particles at various volume fractions are used as fillers for Liner MediumDensity Polyethylene (LMDPE) to verify those theoretical models. A comparison with the experimen...

Rather than using graphene oxide, which is limited by a high defect concentration and cost due to oxidation and reduction, we adopted cost-effective, 3.56 nm thick graphene platelets (GnPs) of high structural integrity to melt compound with an elastomer-ethylene-propylene-diene monomer rubber (EPDM)-using an industrial facility. An elastomer is an amorphous, chemically crosslinked polymer gener...

This work presents a novel computational approach, the DSC regularized Dirac-delta method, for vibration analysis of functionally graded graphene-platelet reinforced (FG-GPLR) porous beams resting on Winkler–Pasternak elastic foundation under moving load. Based Timoshenko beam theory, energy functional model is represented by newly constructed basis function and minimized variational principle....

The mechanic...

in this study, thermoplastic polyolefin elastomeric (tpo) nanocomposites were fabricated by friction stir processing. the effect of different pin geometries on clay dispersion and mechanical properties of the tpo nanocomposite reinforced with 3% wt nanoclay has been first investigated. the optimum pin geometry namely threaded cylindrical pin was then used to fabricate the nanocomposites contain...

We have developed the Halpin system to implement our multimodal conversational model for information retrieval. This dialogueoriented interface allows the access to a digital library database, on the internet, in a natural language way, and gives its oral responses via usual browsers. The results of the first experiments show that the Halpin system provides some interesting dialogues (in partic...
