Abstract This article presents the assessment of bulk and in situ mechanical properties rubber–wood–plastic composites (RubWPC) their correlations, aiming to obtain a thorough understanding behaviour RubWPC, which is an essential prerequisite realising optimal design applications. Dynamic analysis results showed that treated with multiple coupling agents (combination maleic anhydride polyethyle...

Natural rubber (NR), regarded as nature's most versatile raw material is obtained from the latex of Hevea brasiliensis, a tree, native to the tropical rain forests of Amazon and introduced on a commercial scale to the Far East during the last century. In India, organised cultivation of rubber started in 1902 on an estate scale by European planters. This crop however came out of the bounds of th...

The use of waste materials to make eco-friendly wood-polymer composites has been explored by many researchers for academic and industrial purposes due the low cost, biodegradability, availability wood flour. Polypropylene (PP)/ground tyre rubber (GTR)/wood flour (WF) were prepared using an internal batch mixer at a temperature 165 °C 8 min, samples injection-moulded 190 with pressure 6 MPa. des...

A study has been undertaken to develop techniques for assessing baseball bat durability and performance. Experimental investigations were conducted by constructing a testing device to simulate the ball-bat interaction occurring in play. A sensitivity study of the machine’s inertia and forces on the bat were found to have a small effect on hit ball speed, and a much larger effect on bat stress. ...

The mechanical properties and morphology of polypropylene/wood flour (PP/WF) composites with different impact modifiers and maleated polypropylene (MAPP) as a compatibilizer have been studied. Two different ethylene/propylene/diene terpolymers (EPDM) and one maleated styrene-ethylene/butylene-styrene triblock copolymer (SEBS-MA) have been used as impact modifiers in the PP/WF systems. All three...

The study attempts to fill a gap in Malaysian forestry economics, an area relatively less probed compared to the other important primary commodities of Malaysia. The core of the thesis are two econometric studies. The first concerns estimating supply and demand elasticities of the three main Malaysian wood products sawlogs, sawnwood and plywood. Demand is split up into export and home demand to...

Guayule (Parthenium argentatum Gray) is a perennial shrub of the Asteraceae family native to arid southwestern U.S. and northern Mexico that produces high-quality, hypoallergenic natural rubber. processing three output streams: high-molecular weight rubber as primary product, mixture resin/low-molecular rubber, fine, dry woody bagasse. The goal this review was evaluate guayule resin source seco...

Waste high fells form a log and twig wood type Leucaena (Leucaena leucocephala), rubber (Hevea brasiliensis), randu (Ceiba pentandra), balsa (Ochroma bicolor) can be used as medium cultivation of Oyster Mushrooms (Pleurotus ostreatus) to increase the value added these four types wood. The research aims analyze potential for white on media wood, nutrient content mushrooms, appropriateness busine...
