- Comparing fiber performance: ASTM C 1399 gives
producers an easy way to measure the toughness of fiber reinforcement in
concrete.
Producers have long been touting the benefits of fiber-reinforced concrete, helping concrete contractors understand how fibers improve the quality and durability of flatwork. Now, recent research and marketing initiatives are enabling producers to communicate to design engineers and code enforcement officials the benefits of fibers in load-bearing concrete applications such ......
- New software aids composite processing and
QC.
* Several recent software introductions for composites design, processing, and quality control offer more sophisticated predictions of both processability and finished part properties. One new product actually controls the process. The new products can separate fiber failure from matrix failure when analyzing composite strength, optimize prepreg lay-up, control vacuum infusion ......
- Effect of autocorrelated data on composite panel
production monitoring and control: A comparison of SPC techniques.
(Processes).
JOHN R. NOFFSINGER (*) R. BRUCE ANDERSON (*) ABSTRACT Traditional statistical process control (SPC) methodology is based on a fundamental assumption that the process data are independent. However, in continuous-type processes, such as composite panel production, the process data are often highly autocorrelated. Under such conditions, traditional SPC techniques are ......
