I want to know the answer to the following question:
What other modern material has joined composites, carbon fiber, titanium, and aluminum to replace wood in the manufacture of sporting equipment?
All the background I'm provided with is that "One noteworthy example of this trend is the golf club commonly known as the wood, the head of which was traditionally made of persimmon wood in the early days of the game of golf, but is now generally made of synthetic materials.". Is that enough to answer the question?
Answer: no
