چکیده

The creation of highly oriented, co-extruded polypropylene (PP) tapes allows the production of recyclable ‘‘all-polypropylene’’ (allPP) composites, with a large temperature processing window and a high volume fraction of highly oriented PP (>90%). The wholly thermoplastic nature of these ‘self-reinforced’ composites implies that the mechanical performance may vary with temperature. This paper describes the mechanical performance of all-PP composites by measuring the mechanical properties of highly oriented PP tapes and subsequent all-PP composites at a range of temperatures by static and dynamic testing methods. The time–temperature equivalence of all-PP composites is investigated by creating mastercurves of dynamic modulus and tensile strength. A comparison of the performance of these composites with commercial glass fibre reinforced polypropylene composites is included. 2006 Elsevier Ltd. All rights reserved.

The mechanical properties of unidirectional all-polypropylene composites

The creation of highly oriented, co-extruded polypropylene (PP) tapes allows the production of recyclable ‘all-polypropylene’ composites, with a large temperature processing window (O30 8C) and a high volume fraction of highly oriented PP (O90%). These composites show little deviation of mechanical properties with compaction temperature. This paper introduces all-polypropylene composites and re...

The Effect of Processing Conditions on the Mechanical Properties of Polypropylene/Mesoporous Silica-Hydroxyapatite Hybrid Nanocomposites

This work focused on the influence of processing conditions on the mechanical properties of polypropylene (PP) and PP/mesoporous silica-hydroxyapatite (PP/MCM-41-HA) hybrid nanocomposites. The mechanical properties of PP were enhanced by adding MCM-41-HA nanoparticles. Neat PP and hybrid nanocomposites based on PP, containing maleic anhydride-grafted polypropylene (PP-g-MA) and MCM-41-HA, were ...

Dynamic Mechanical Analysis of Compatibilizer Effect on the Mechanical Properties of Wood Flour-High-Density Polyethylene Composites

In this study, effect of MAPE (maleic anhydride polyethylene) as the compatibilizer on the mechanical properties of wood-flour polyethylene composites has been investigated by using Dynamic Mechanical Analysis (DMA). Composites were made at 25% and 50% by weight fiber contents and 1% and 2% compatibilizer respectively. Controls were also made at the same fiber contents without the compatibilize...

Evaluation of Mechanical and Thermal Properties of Polypropylene Modified with Nanostructured ZSM-5 Zeolite

Polypropylene (PP) has been one of the most widely used polymers due to the versatility and cost benefits obtained with this material. In this work, composites of PP modified with nanostructured ZSM-5 zeolite were prepared and their thermal and mechanical properties were evaluated. Zeolites were synthetized by hydrothermal method and the crystallization time was modified to evaluate the effect ...

Fatigue Properties of Highly Oriented Polypropylene Tapes and All-polypropylene Composites

This study describes the fatigue behaviour of newly developed all-polypropylene (all-PP) tapes and woven composites [1], with reference to the composite processing conditions, testing temperature and comparison to commercial alternatives. The possible damage development mechanisms are also part of the present paper. All-PP tapes used in this study are highly oriented (90 wt% oriented phase) and...
