Las Vegas--Thermoplastic composites may soon give Mother
Nature a helping hand in improving the strength of wood products.
At the Composites 2000 show, Dow Chemical Co. (Midland, MI) and
Pacific Woodtech Corp. (Burlington, WA) announced their intent to enhance
laminated veneer lumber (LVH) with reinforcements made from pultruded
thermoplastic composites. The resulting products will initially target
industrial applications--such as scaffold planks.
The reinforcing pultrusions will be produced using Dow's FULCRUM
technology, which employs a thermoplastic polyurethane as the resin matrix for
continuous glass fiber. These composites have "all the key mechanical attributes
for a structural reinforcement material," says Faye Miller, Dow's business
development manager for lumber. Typical mechanical properties--for a 2- x 20-mm
strip--include a tensile strength of 1,000 MPa, a tensile elongation of 2.2%,
and a transverse flexural strength of 120 MPa. FULCRUM offers these strength
benefits at a density of just 1.91 grams/cubic cm.
Truchard will be presented the award at the 2014 Golden Mousetrap Awards ceremony during the co-located events Pacific Design & Manufacturing, MD&M West, WestPack, PLASTEC West, Electronics West, ATX West, and AeroCon.
In a bid to boost the viability of lithium-based electric car batteries, a team at Lawrence Berkeley National Laboratory has developed a chemistry that could possibly double an EV’s driving range while cutting its battery cost in half.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
