Hmm... I don't like being pessimistic but I can't see them using wood pulp to make badminton racquets to be honest. An interesting concept nonetheless and I do like reading about new "potential" badminton racquet materials, but I'm just not convinced by is one.
Its probably suitable for a lot of other applications, but for badminton racquets, you need more than just elastic mod and tensile strength.
Besides, the marketing department at Yonex would probably have a hard time making it sound sexy... Woodpulp-ex 1000 anyone?
