There's a relatively new, mysterious material called "spectra". It is very light, forgiving, and extremely strong/tough/durable and can be applied to many applications. Spectra's been used in bullet-resistant vests, composite baseball/softball bats and fishing line. In bats, spectra is woven into carbon fiber. This sparked Panda's interest because composite bat technology is not too different than badminton racket technology.
