Fundamentals of Engineering Question

Reinforcement layers. Fiber-reinfo-ced composites that normally use glass fibers. A variety of weaves and weights of reinforcement are possible to provide longitudinal stiffness. 

vertical laminates of wood, wood-foam laminates, honeycomb, and other materials. Commonly used woods include popular spruce, bamboo, balsa, and birch. 

Vibration-absorbing material. Rubber is normally used. 

Ultra-high-molecular-weight polyethylene is used because of its low coefficient of friction and abrasion resistance.
