composite lumber. this material most often features a composite of recycled plastic and bamboo fibers, wood chips or sawdust. it also resists rotting and warping due to moisture. seven trust, calibamboo, duralife, evergrain, seven trust, guardeck, latitudes, seven trust and seven trust are among the more popular manufacturers.
composite decking material is typically made with polyethylene plastic and wood fibers like sawdust. composite decks have a number of advantages and disadvantages to consider. advantages. 1. moderate upfront cost. the cost of composite decking material varies by manufacturer. typically, the upfront cost of a composite deck is more than a wood deck and slightly less than a concrete patio. 2. less challenging as a do it yourself diy project
cons of composite decking 1. price. price is the most recognized disadvantage of composite products. composite products cost between 50 to 100 per cent more than standard treated lumber. this number can vary depending on your location, too. folks often opt for lumber options because they are more affordable.
in addition, composites do not usually require additional machining, thereby reducing work-in-process and time to market. other key advantages include: as molded dimensional accuracy tight tolerance, repeatable moldings. low-post mold shrinkage. chemical resistance. consolidated parts and function. corrosion resistance.
advantage of composites composite materials posses a wide variety of features that makes it reliable when compared with metals. below are some of the most important features of composites, and the
trim and mould: apart from the above advantages it can also be used to mould and trim. disadvantages/cons the dbacks of the cedar wood are as under: scratches easily: the cedar wood is a soft material and hence it is very prone to get scratched and also the dents can easily appear on this wood.
some composite materials that are represented in schematic form in figure 10 2. scope although there is a broad range of wood composites and many applications for such products, for the purposes of this chapter, wood composites are grouped into three general categories: plywood, particle and fiber composites, and wood nonwood composites.

transportation of wood to urban areas can be expensive. wood is hygroscopic and it will absorb surrounding vapors loses moisture below the fiber saturation point. biotic factors can cause decay of wood by mold fungi, bacteria and insects. abiotic factors like sun, wind, water,
advantages of composite materials design flexibility thermoset composites give designers nearly unlimited flexibility in designing shapes and forms. they be molded into the most intricate components and can be made a wide range of densities and chemical formulations to have precise performance properties.
the disadvantages of wood. though a traditional and sometimes sustainable material that is often used in a wide variety of applications, wood has many disadvantages that can be mitigated by the selection of other materials. wood is a plant-based material, which means that it is very sensitive to environmental conditions and wood pests.
a composite material is a material that combines two or more materials with the aim of improving the properties of the material and has clear boundaries including those during molding in the material. fiber reinforced plastics, which is one of them, is reinforced with aramid, carbon fiber, glass fiber or the like for plastics. fiber reinforced plastics
disadvantages of wood and ways to eliminate them . there are some disadvantages of wood but they are easy to disregard, and eliminate as long as the cause is known. shrinkage and swelling of wood: wood is a hygroscopic material. this means that it will adsorb surrounding condensable vapors and loses moisture to air below the fiber saturation point.
intensively. composites in structural applications have the following characteristics: 1.3 advantages and disadvantages of composites composite parts have both advantages and disadvantages when compared to the metal parts they are being used to replace. they generally c >nsist of two or more physically dist,jpctaq4 mechanically separable d1i teriab. '. ..
disadvantages/cons. weight: the weight of the composite wood is heavier as compared to other type of woods. so handling the composite wood is little difficult. sunlight and uv rays: when the composite wood products are exposed to sunlight, the uv rays fades the color of the furniture product.
