Prepreg Tail Bag production

June 27th, 2015To the top
Prepreg Tail Bag productionIt sure was a learning process... Trying no less than 15 types of carbon prepreg fabrics from seven different manufacturers.
Also: which kind of agent releases the product best from the mould? Lots of difference there: varying from severe sticking to the mould to effortless loosening.
Next came all kinds of foils and films, vacuum blankets, vacuum pumps, vacuum bags, oven arrangements, completely illogical oven control programs and two weeks ago to cap it all an imploding mould. 138 degrees centigrade sure bakes the product fast but proved to be a bit to much for the mould. Result: about one hundred hours of work lost and another delivery delay.
We have now new moulds with heat resistant epoxy and from now on the baking temperature is lowered to around 110 degrees centigrade. Takes a bit longer, but the moulds and foils last much longer.
Anyway, the production process has started and the new prepreg cases are less than half a kilogram. So that's lighter than a 17 litre top bag. The possibilities to make nice and light weight products have increased significantly!

Almost tailwind.....

Almost tailwind.....Still inspiring to have this displayed while commuting with jeans on (although click pedals!)

Bike: M5 Carbon High Racer, 13 degrees Celsius, Beaufort 5 as an almost tailwind
 

One day of delay for all.....

One day of delay for all.....Despite the fact that it's high season in recumbent business there was a strong urge to finish a one-day project in order to help homeless swifts. A neighbouring farmer had just renovated the roof of his barn which led to the vanishing of breeding places for these wonderful birds. By installing these special double-deck wooden cottages we hope to eliminate this problem. Special thanks to Daniël Siepman for assisting with this in-between job.

First M5 Carbon Tail Bag case (21 ltrs.) leaves molds

March 6th, 2015To the top
First M5 Carbon Tail Bag case (21 ltrs.) leaves moldsFinally there is a neat and lightweight Tail Bag available for both the M5 Carbon High Racer and the M5 M-Racer. The only additional part you need for assembly is the already available carbon carrier/fender. The Tail Bag attaches to the carrier/fender with a simple Velcro system. The lid is also put into place with this material. Of course there is a possibility to add some kind of lock system as well. The product is currently made with a wet lay-up system but will probably change to a pre-preg technique. This saves time and weight. The weight is now close to 800 gram, which is definitely low weight, but with the pre-preg method it will drop to a mere 500 gram. And last but not least: because of the perfect fit to the rider this Tail Bag reduces the heart rate with around 10%. Or consider the gain with the same heart rate: speed will increase with km/h (1,3 mile/h) when cruising with 40 km/h (25 mile/h)!

Takes quite a lot of extra training to equal these numbers!
