Modern materials are new, often with properties which eliminate problems with alternative materials.
Composites are a mixture of materials, combined to improve the properties.

Modern materials only provide advantages to designers and users.

Modern materials are often difficult and expensive to produce and are also difficult to recycle.

Modern material - are continually being developed through the invention of new or improved processes
Working property - the way in which a material responds to an external force or certain environment; also referred to as mechanical properties
Physical property - the characteristics of a material, such as appearance and features
Composites - combine the properties of two or more materials without being mixed at a chemical level
