in the technical sense treated here, dunnage is inexpensive or waste material used to load and secure cargo during transportation; more loosely, it refers to miscellaneous baggage, brought along during travel. the term can also refer to low-priority cargo used to fill out transport capacity which would otherwise ship underweight.
other materials are made from synthetic fibers, primarily from petrochemicals, which are not generally biodegradable. common synthetic materials include: nylon was first produced in 1935. nylon is a thermoplastic silky material. it became famous when used in women's stockings 'nylons' in 1940.
material failure theory is the science of predicting the conditions under which solid materials fail under the action of external loads. the failure of a material is usually classified into brittle failure or ductile failure .depending on the conditions such as temperature, state of stress, loading rate most materials can fail in a brittle or ductile manner or both.
the acronym mesc stands for material and equipment standards and code. it is a tool of the materials department for standardisation and handling of materials used in business. it was created in 1932 for internal use by shell, but later on licensed to every company who wished to pay for it.
nonwoven fabric is a fabric-like material made from staple fibre short and long fibres continuous long , bonded together by chemical, mechanical, heat or solvent treatment.the term is used in the textile manufacturing industry to denote fabrics, such as felt, which are neither woven nor knitted. some non-woven materials lack sufficient strength unless densified or reinforced by a backing.
the restriction of hazardous substances directive 2002/95/ec, rohs 1 , short for directive on the restriction of the use of certain hazardous substances in electrical and electronic equipment, was adopted in february 2003 by the european union.. the rohs 1 directive took effect on 1 july 2006, and is required to be enforced and became a law in each member state.

terms used to describe smart materials include shape memory material smm and shape memory technology smt . types. there are a number of types of smart material, of which are already common. some examples are as following: piezoelectric materials are materials that produce a voltage when stress is applied. since this effect also applies in a .
because of their application in the computer and photovoltaic industry—in devices such as transistors, lasers, and solar cells—the search for new semiconductor materials and the improvement of existing materials is an important field of study in materials science. most commonly used semiconductor materials are crystalline inorganic
cob is an english term attested to around the year 1600 for an ancient building material that has been used for building since prehistoric times. the etymology of cob and cobbing is unclear, but in several senses means to beat or strike, which is how cob material is applied to a wall.
