its true, TP composites eliminate hand application of your matrix (i.e. pouring the resin from a cup). From a big manufactures point of view that can significantly reduce ski to ski variations and automate more of the process.

that with the recycleability and lack of VOC's make TP composites pretty attractive. plus that Twintex product is dirt cheep.

I wouldnt be surprised to see it, but only from K2 for the next 4 years I guess..

I've been working with composites for 3 three years in a R&D facility, both with thermoplastics and thermosets. Only main disadvantages of TP's are high cure pressure and themperature. (5-20bar and 120-320C).
At these pressures/temperatures, the risk of fire is large. ( had an autoclave fire 7 weeks ago)

Still.. You need an autoclave.

I don't think an autoclave is necessary - they can be processed w/ a compression molder.

Compression moulding works for unreinforced plastics. A heated press is also an option but the temperature needs te be controlled very precise

have you made any progress on this? I'd love to hear where this project is going.

I'm designing a bio ski according to the craddle to cradle principles.
The fiber will be hemp (triax) and as a resin i'm using PE from garbage bags! When I get any results I post it here

that would be awesome if it works out! I've got entire cabinets full of shopping bags from the grocery store, it would be really awesome to find good use for them.
