FiberSource: Short History of Manufactured Fibers/
production of polyester fiber transformed the “wash and wear” novelty into a revolution in textile product performance. Polyester's commercialization in 1953 was accompanied by the introduction of triacetate. The majority of the 20th century's basic ma...
Corn Being Used to Produce Clothing and Other Textiles
College of Textiles. "It's a way of making a synthetic product from natural, renewable resources, instead of having to use a byproduct of the oil industry." The product, which has been named Natureworks, is the brainchild of Minnesota-based Cargill Dow....

Demoworks/ page 19 Strengthen Ceramic Dishes (Ceramic Composites) Objective: To show that properties of a whole (composite) are stronger than the parts Keywords: tension, compression, composite Materials: • Corelle Dish Procedure: Hold up the Corelle dish and smack it against a table. Be sure the table doesn’t have sharp points or particles on it (which may cause it to fracture). Place a nick in the plate and smash it again. This time the plate should break into many pieces

Demoworks/ page 17 Paper Clip Fatigue Objective: To explore the impact <span class="highlight">of</span> cyclic fatigue and determine the number <span class="highlight">of</span> cycles- to-failure in metals. Keywords: mechanical <span class="highlight">properties</span>, fatigue , S-N curves Materials: • A box <span class="highlight">of</span> Jumbo Smooth Paperclips Procedure: Bend a paperclip repeatedly to 45º and record the number <span class="highlight">of</span> cycles until failure. A cycle starts at the bending angle and finishes at 0º. Repeat this experiment to bending angles <span class="highlight">of</span> 90 and 180º. Caution must be taken to assure

Portland Cement
drying shrinkage stresses usually exceed the concrete tensile strengths, causing cracking. The advantage of using expansive cements is to induce stresses large enough to compensate for drying shrinkage stresses and minimize cracking (ACI Comm. 223 1983; Hoff et al. 1977). Physical an...
