<p class=MsoNormal><span style='color:#1F497D'>Characteristics are generally
related to qualities of a material such as texture, feel, appearance (the way
it looks), its grain structure, shape, colour and other aesthetics.<o:p></o:p></span></p>
<p class=MsoNormal><span style='color:#1F497D'>Properties relate to the more
physical, mechanical and chemical elements that allow a material to carry out a
particular function. Tensile strength, compression strength, hardness,
toughness, absorption, elasticity, weatherability, stiffness and density are
examples of this.<o:p></o:p></span></p>
<p class=MsoNormal><span style='color:#1F497D'><o:p> </o:p></span></p>
<p class=MsoNormal><span style='color:#1F497D'>I teach the words differently so
that students can make a table for materials that show the characteristics and
properties separately so that they can see the clear distinction between them.<o:p></o:p></span></p>
<p class=MsoNormal><span style='color:#1F497D'><o:p> </o:p></span></p>
<p class=MsoNormal><span style='color:#1F497D'>Also hope that this can help you

<p class=MsoNormal><span style='font-size:10.0pt;font-family:"Arial","sans-serif";
color:navy'>All I can say is that … when you really look into
characteristics and properties over a wide range of materials there is a lot of
overlap. Sometimes in timber, characteristics refers to the appearance which is
slightly different from your interpretation below for fabric, and properties
refers more to how the material behaves.<o:p></o:p></span></p>
<p class=MsoNormal><span style='font-size:10.0pt;font-family:"Arial","sans-serif";
color:navy'>My approach is to use the two words together and not be too
particular about the difference.<o:p></o:p></span></p>

<p class=MsoNormal>Hi all,<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Hoping for some clarification of terms.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>In the DESIGN FACTORS & APPLICATIONS the term Materials
– Characteristics & Properties is used. However when looking at
fabrics in the text books the term Characteristics never appears.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>My interpretation was<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Materials characteristics – what the fabric can do
(i.e stretch, transparent)<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Material properties – The origin of the fabric and its
construction (i.e polyester plain weave)<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>However in the text books the use the term Properties to
discuss what the fabric can do and a whole range of terms to discuss the origin
& construction method (i.e identification, forms)<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I am of the understanding we should be using consistent
terminology based on the Design Factors & Fundamentals.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Any advice/feedback welcome !<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
