Research Materials Marley Emerich DT AEvery designed 3-D product is made from a material. Materials come in many different forms. Ex: timber, metal, plastics, and others known as resistant materials. Textiles, cloth, paper, etc, are known as compliant materials. for our moving toy project we are going to consider mainly “resistant” materials. Wood: There are two types of natural wood, softwood and hardwood (ex. Cherry Oak). The names don’t really have anything to do with the hardness of the wood, it depends on the tree. Also, there are manmade woods such as blockboard and chipboard which are made in factories. Metals:Metal comes naturally form the ground in the form of a solid or liquid. There are two types of metal. Ferrous metal, which contains iron and non-ferrous metal, which do NOT contain iron. Metal’s today are used for many things including jewelry, electronics, and screws. Plastics: Made in 1862. A material that the vast majority of objects worldwide is made of. Plastic can be melted and shaped but it is harmful to the environment. There are two types of plastics, but both are (all plastic is) base on polyer (a molecule). Textiles: A flexible material made of natural or artificial fibers. Textiles are formed by weaving, knitting,
crocheting, knotting, or pressing fibers together. They can be used for clothing, place mats, blankets, hankercheifs, rags,shoes, towels, curtains, to even parachutes and balloons.
