AbstractThe paper describes refinements of rapid laboratory assessment of the mechanical performance of timbers used in the marine environment as regards their resistance to indentation, impact abrasion from smooth and sharp abrasives and to dynamic impact loads when wet. Ten tropical and home-grown hardwoods, five softwoods and a wood–polymer compound were examined.

UHMW Plastic Material | UHMWPE Properties & Uses

UHMW (ultra high molecular weight polyethylene) is an extremely tough plastic with high abrasion and wear resistance. The versatility of polyethylene has made it a popular plastic for countless industrial applications that require durability, low friction, and chemical resistance.

What is Abrasion Resistance? - Definition from Corrosionpedia

Oct 06, 2015· Abrasion resistance is the ability of materials to withstand the effects of abrasion, for example: repeated wearing, rubbing, scrapping, etc. Abrasion-resistant materials are handy in inhibiting mechanical wearing and damage. They can be used in the construction of space shuttle components. The abrasion resistance of high-performance concrete ...

Wear Resistance | Premium Floors

The abrasion resistance and durability of the coating is measured by counting the number of rotations until the coating is worn through. This wear through is confirmed by the application of a red dye to show that the lacquer is removed and that the wood is now porous. 50 rotations of the turntable represent approximately 12 months of wear in a ...

Properties of Timber- Qualities of Good Timber & Wood

Warping: Timber of good quality can not be influenced by environmental change with the season. Durability: A high-quality timber has the property to withstand the disease or other insect parasite attack. This standard of resistance increases timber. Elasticity: Another property elasticity implies that after use, timber should have its own form.

Floor Finishes — AMR Timber Flooring

Timber floor finishes can be grouped into four broad categories. These are the oil-based finishes, composite finishes (mixes of oil-based and solvent based polyurethane finishes), solvent based polyurethane finishes and water based finishes. ... generally with limited flexibility but much greater abrasion resistance. Consequently, this greatly ...

WEARING SURFACES FOR TIMBER DECKS

On timber bridges, a wearing surface is one of the most important components of the superstructure and serves two primary purposes. First, it provides a safe, smooth surface for vehicle traffic and improves the poor skid resistance of treated timber decks. Second, the wearing surface protects the deck from the abrasion and physical action of

Timber for marine and freshwater construction

timber given in Table 3, of CP112:1967: Imperial Units, or 1971 : Metric Units. Of all constructional materials, timber is unique in that it does not corrode. Corrosion, coupled with abrasion, may result in the loss of thickness in steel, or exposure of concrete reinforcement.

Jarrah | The Wood Database - Lumber Identification (Hardwood)

Rot Resistance: Jarrah is rated as very durable regarding decay resistance, and it is also quite resistant to insect attack. Workability: Jarrah tends to be difficult to machine on account of its high density and interlocked grain. Jarrah also has a moderate blunting effect on cutting edges. Jarrah turns, glues, and finishes well.

Timber: Fire-Resistance, Qualities,Strength, Decay ...

Fire-Resistance of Timber: As a general rule, the structural elements made of timber ignite and get rapidly destroyed in case of a fire. Further, they add to the intensity of a fire. But the timber used in heavy sections may attain high degree of fire-resistance because the timber is a very bad conductor of heat.
