Steel slags have a chemical composition close to that of the Portland cement clinker, mainly constituted by calcium-silicates and calcium-ferrites, which makes this industrial waste potentially usable as a raw material for cement and concrete production [91].The presence of steel slag in the clinker manufacturing process reduces the …
Fig. 1 shows the schematic diagram of the FW method. A stationary rotating mandrel is used in the FW process, while a carriage arm moves horizontally with the mandrel. The arm contains a winding pay-out eye, which groups and dispenses pre-impregnated fibers called rovings; rovings are usually carbon, Kevlar™, glass fiber, or a …

Cadmium is a common heavy metal that can cause serious harm to human health, even in trace amounts. Therefore, it is of great significance to develop environmentally friendly, inexpensive, and readily available adsorbent materials with high selectivity. By preparing ion-imprinted composites on the surface of a suitable carrier …
Open contact molding in one-sided molds is a low-cost, common process for making fiberglass composite products. Typically used for boat hulls and decks, RV components, truck cabs and fenders, …
In the pultrusion process, wet fiber is pulled thorough a shaped die that is really hot. The fiber and resin goes in one end all goopy and comes out a fully cured part. Like extrusion (which is a push process), pultrusion (a pull process – can't push on wet fiberglass!) produces long things with a consistent sectional shape.
Step 3: Core Making. The third step of the sand casting process (i.e. core making) involves creating the internal features of the final product that cannot be formed by the mold cavity alone. Cores are inserts made of sand or other materials that are placed into the mold to create voids (cavities) within the final casting.
1. Introduction. Concrete is the most widely used manmade material with an annual production exceeding 25 billion tons globally [1].The development of multifunctional concretes that exhibit electrical conductivity alongside mechanical properties, opens the door to various sustainable and smart infrastructure applications [2], [3], [4].These …
While selecting a chemical treatment or processing technique to fabricate composites, various factors are considered like fiber selection, extraction method, selection of manufacturing process, mechanical and thermal properties of fibers, etc. Processing techniques that are used to fabricate natural fiber composites are shown in Table 2.
