Non-Organic Material: Termites thrive on organic substances like wood but cannot process synthetic materials. Moisture Resistance: PVC panels resist moisture, which discourages termite colonies from forming in the first place. Chemical Composition: The inclusion of termite-repelling additives in some PVC panels further enhances their resistance.
The principle of fatigue-resistant materials does not require specific layouts of the two constituents of large stiffness contrast. A composite of unidirectional fibers is anisotropic and resists crack in one direction. A laminate of multidirectional fibers is approximately isotropic in plane and resists cracks in many in-plane directions.
Chemical-resistant materials play an important role in packaging applications, particularly in the packaging of cleaning agents, reagents, and other chemicals. They're also useful for manufacturing tooling. During use, jigs and fixtures are often exposed to chemicals (liquid, gas or solid). Chemical resistance ensures they don't degrade ...

Water-resistant materials can protect against splashes and spills, while also providing some protection against rain and water droplets. Waterproof: If a fabric is waterproof, it means it offers a protective barrier. These kinds of materials are usually enhanced with waterproof coatings or made from waterproof substances, which help them ...
Chemical-resistant materials don't require surface treatment; they are able to withstand exposure to chemicals such as bases, solvents, and acids. Without chemical-resistance, a material may erode, soften, or become misshapen. This is due to the chemical's molecules diffusing within the material and pushing the polymer chains apart.
Maximum continuous operating temperature is crucial, as is the material's chemical resistance and mechanical properties. Types of Heat-Resistant Plastics. Choosing the right heat-resistant plastic depends on understanding the different types available. For instance, polyetheretherketone (PEEK) is a semi-crystalline thermoplastic that can handle ...
Next, they examined the materials under a microscope and compared each impact's physical aftermath. "In the architected materials, we saw this morphology of small cylindrical craters after impact," Portela says. "But in solid materials, we saw a lot of radial cracks and bigger chunks of material that were gouged out."
Wear resistance is the ability of a material to resist the progressive loss of volume from its surface through mechanical actions such as repeated rubbing, sliding, or scraping. Wear-resistant materials minimize friction between mating surfaces, allowing parts to retain their form and integrity for longer in applications involving contact between load-bearing surfaces.
A nanoarchitected material consists of patterned nanometer-scale structures that, depending on how they are arranged, can give materials unique properties such as exceptional lightness and resilience. As such, nanoarchitected materials are seen as potentially lighter, tougher impact-resistant materials. But this potential has largely been untested.
Tough and impact-resistant materials: A beginner's guide "Toughness" is a combination of an object's strength (how easily it breaks) and ductility (how easily it deforms). In this way, toughness and impact resistance are one and the same – especially in material science, as toughness is a measure for how easily your part breaks upon ...
This chapter argues the ways in which resistant materials should ideally feature within technology and design education at primary and secondary schools. "Resistant" materials are those that require application of substantial force to process, such as metals, plastics, and woods, but also extends into many other material families.
Tough materials are naturally more impact-resistant than other materials, but various factors can affect a material's impact resistance. For example, plastics tend to be more brittle at cooler temperatures and tougher at warmer temperatures. Prolonged exposure to elevated temperatures and UV light tends to decrease a plastic's toughness.
Treated cellulose insulation provides a fire-resistant barrier, giving flames less chance to spread. Helen H. Richardson/Getty Images. Natural building materials such as lumber and cotton typically offer very poor fire resistance compared to dense concrete and plaster. The plant-based substances make for easy fuel and are quickly consumed by flames. However, …
Chemical resistant materials are required for various uses and in many environmental conditions. Materials with high chemical resistance in many unfavorable environments can improve the efficiency and productivity of the industry while reducing the necessity for component spare parts and making the development more profitable.
Corrosion resistant materials are substances that are able to withstand the damaging effects of acids, salts, and bases, as well as the corrosive action of gaseous and liquid products. These materials, such as stainless steels, nickel alloys, titanium, and ceramics, are specifically designed to resist corrosion under certain conditions.
