The photos on this page show some of the rigid boards that Dream
produced for a bio-medical customer. The requirements called
for a 2 foot wide by 6 foot long panel that did not deflect more
than 0.25" with a 200 lb load at the center. The board could
not weigh more than 30 pounds and needed to be radiotranslucent. |

|
Dream's very first part weighed 16 lbs and deflected
less than 0.1" with a 200 lb load. Dream's part exceeded
the customer's expectations. |

The resin content difference between numerous boards varied by
only 25 grams. Resin is fairly high in Coefficient of Thermal
Expansion (CTE), while the carbon fiber is extremely low to negative
in CTE. Leaving in more, or less, resin will increase or decrease
the CTE of the final part, assembly, etc., as well as change
the thickness, mass, etc. Dream has 18 years of heritage producing
athermal instrument structures for the incredibly tight mechanical
& thermal tolerances of opto-mechanical systems. We control
our resin content to a much finer level. Taking things to a higher standard is what Dream is known
for and the reason it was the first of many technologies brought
in-house. |

Many believe pre-pregs are the utmost in
performance. Because Dream's owner lives in the details and knows
performance is within those details, he has learned to ask the
right questions. Pre-pregs can vary by +/-20% or more in resin
content. In this board example a 20% resin variation would have
been more than 1450 grams of resin. This puts Dream's 25 grams into perspective
and is one of many reasons Dream's products are both unique and
help Dream's customers stand out in their respective markets. |

Dream designed and produced two identical units as
prototypes. No changes were required for the follow on units.
This saved the customer time and money as no further development
or testing iterations were required for the product. Due to Dream's
18 years of heritage producing carbon fiber parts this particular
product required no R&D, since the first units worked better
than the customer expected from the start. |
