Abstract Cysteamine functionalised reduced graphene oxide (rGO) was grafted to polypropylene-graft-maleic anhydride (PP-g-MA) and subsequently melt blended with PP. The covalent bridging of rGO PP-g-MA via the cysteamine molecule co-crystallization are routes promoting interfacial interactions between PP matrix. A rheological percolation threshold achieved for a nanofiller loading 3 wt% 5 wt%, ...

The Apitong wood species has long been the most popular choice for transportation, such as in trailer decking and shipping container floors. However, is depleting due to its excessive usage. Bamboo fiber provides an alternative low density (608–780 kg/m 3 ) lightweight attributes. This study explores 1) development properties of bamboo-thermoplastic composites with different content, 2) applica...

This present research aims to predict the mechanical behavior of composite and hybrid composites based on a polypropylene matrix (PP) reinforced by organic/inorganic naturally occurring fillers using analytical numerical models. It also demonstrate effect hybridization global stiffness material. In this study, Voigt-Reuss models, Halpin-Tsai equations, Hirsch model, simulation are applied effec...

As a significant part of municipal solid waste (MSW), waste cardboard (CB) is a sustainable, inexpensive, and rich source of cellulose. Previous studies of polyolefin/CB composites have reported modest enhancement to major reduction in modulus and major reduction in elongation at break values relative to neat polymer. Here, green hybrids of low density polyethylene (LDPE) and polypropylene (PP)...

INTRODUCTION Composite biomaterials designed for the repair of abdominal wall defects are composed of a mesh component and a laminar barrier in contact with the visceral peritoneum. This study assesses the behaviour of a new composite mesh by comparing it with two latest-generation composites currently used in clinical practice. METHODS Defects (7x5cm) created in the anterior abdominal wall o...

Carbon black (CB)-filled polypropylene (PP) with surface resistivity between 106 and 109 Ω sq-1 is the ideal antistatic plastic material in the electronics and electric industry. However, a large amount of CB may have an adverse effect on the mechanical properties and processing performance of the material, thus an improved ternary system is developed. Blends of CB-filled PP and polyamide 6 (PA...

As a cementitious material, geopolymers show a high quasi-brittle behavior and a relatively low fracture energy. To overcome such a weakness, incorporation of fibers to a brittle matrix is a well-known technique to enhance the flexural properties. This study comprehensively evaluates the short and long term impacts of different volume percentages of polypropylene fiber (PPF) reinforcement on fl...
