Understanding the Wear Properties of Basalt Fiber Reinforced Polymers

  The extent to which the flavor and texture of your food depends on how you break down and combine chains of protein, carbohydrate and fat molecules. This reaction is usually caused using heat, but you can also trigger or accelerate chemical reactions by introducing new enzymes into your food that can change the molecular composition. Cooking is one of the best examples of composites in our daily lives. A composite material is a combination of two or more constituent materials with different physicochemical properties; the resulting composite has properties that are different from those of the individual elements. Although composites are ubiquitous, we are often unfamiliar with the original elements used to make them and therefore cannot understand how the combination of materials changes the properties. But in cooking, you can experience the individual elements firsthand as you place them in a bowl and then create a new dish that tastes very different from each of the original ingred

Basalt fiber: an alternative to glass?

  Basalt is a hard, dense volcanic rock that can be found in most countries around the world. It is an igneous rock, which means it starts in a molten state. Basalt has been used in casting processes for many years to make tiles and slabs for architectural applications. In addition, cast basalt linings for steel pipes have shown very high wear resistance in industrial applications. Basalt is also used as an aggregate in concrete when crushed. Recently, continuous fibers extruded from natural refractory basalt have been investigated as an alternative to asbestos fibers in almost all of its applications. Over the past decade, basalt has emerged as a strong contender in the field of fiber reinforcement for composites. Proponents of this latecomer claim that their product offers similar properties to S-2 glass fibers at a price point between S-2 glass and E-glass, and may offer manufacturers a cheaper alternative to carbon fibers for producing the latter products representing over-design.
