2.9 ~ Performance characteristics of modern materials

Define modern materials

Materials that are developed throught ht invention of new or improved processes

Examples of modern materials

Kevlar, precious metal clay (PMC), high-density modelling foam, polymorph

Kevlar features

Aramid fibres with high cut and heat resistant properties

Kevlar uses

Body armour, cut-proof gloves and aprons, aerospace applications, surfboard components, puncture-resistant bicycle tyres

Precious metal clay (PMC) features

Clay consistency material made up of fine metal particles Works like ceramic clay, easily mouldable, easy to shape and form, sets hard once fired with a kiln or butane torch Inexpensive compared to solid metals such as silver

Precious metal clay (PMC) uses

Jewellery Decorative items Small sculptures Fobs

High density modelling foam features

Polyurethane closed cell foam blocks or sheets. Lightweight, easy to work with using traditional woodworking tools, CNC miller/router, sands easily to allow intricate shapes and forms to be created

High density modelling foam uses

3D modelling Prototypes

Polymorph features

Granules that become mouldable at 60 degrees. Can be heated in water or with a hair dryer. Solidifies at room temperature. Available in liquid form. Liquid at room temp and solidifies at 2 degrees

Polymorph uses

Modelling, shaping, ergonomic handles, prototype mechanical parts
