Composite materials (such as carbon fiber reinforced composites and glass fiber reinforced composites) are widely used in the field of sports equipment due to their advantages of lightweight, high strength, and design flexibility.

Below are some typical application scenarios and specific examples:

Golf Clubs
Application Areas: Shaft, club head.
Material Advantages: Carbon fiber shafts are 30%–50% lighter than traditional steel shafts, enhancing swing speed and control. Their high rigidity reduces energy loss during impact, resulting in greater shot distance.

Bicycles
Application Areas: Frame, wheelset, front fork.
Material Advantages: Carbon fiber frames weigh only around 1 kg (compared to about 3 kg for steel frames) while maintaining high rigidity and shock absorption. The fiber layup direction can be customized to optimize strength in specific areas (e.g., bottom bracket stiffness, rear fork vibration damping).

Tennis Rackets
Application Areas: Frame, handle.
Material Advantages: Carbon fiber combined with epoxy resin provides high torsional stiffness, reducing vibration on impact. The lightweight design (approximately 250–300g) allows for faster swings.

Skis and Ski Poles
Application Areas: Core, top sheet of skis, and shaft of ski poles.
Material Advantages: A hybrid structure of carbon fiber and glass fiber enhances elasticity and impact resistance. Reduced weight (carbon fiber ski pole shafts are about 20% lighter than aluminum) makes high-speed skiing easier and more efficient.

Fishing Rods
Application Areas: Rod body and guide ring brackets.
Material Advantages: Carbon fiber rod bodies are lightweight and highly sensitive, allowing anglers to detect subtle bites. High-modulus carbon fiber offers exceptional strength, making them suitable for saltwater fishing and catching large fish.

Badminton Rackets
Application Areas: Frame and shaft.
Material Advantages: Carbon fiber frames are lightweight (around 80–90g), enabling faster swing speed and more powerful smashes. Nano resin enhances flex resistance, extending the racket’s service life.

Rowing Boats and Paddleboards
Application Areas: Hull and paddle blades.
Material Advantages: Carbon fiber hulls are lightweight (approximately 40% lighter than aluminum boats), reducing water resistance. Excellent corrosion resistance makes them ideal for prolonged exposure to seawater.

Baseball/Hockey Sticks
Application Areas: Shaft and hitting surface.
Material Advantages: Carbon fiber laminated structure enhances rebound performance, increasing hitting distance by 10%–15% compared to wooden bats. Superior fracture resistance compared to traditional wood or metal.

Sports Protective Gear
Application Areas: Helmets, Knee Pads, Body Armor.
Material Advantages: Carbon fiber + Kevlar composite materials offer high impact resistance (e.g., NFL helmets). Lightweight design reduces athletic burden.

Emerging Fields
Smart Sports Equipment: Carbon fiber drone racing frames, e-sports chair frames.
Adaptive Sports Gear for People with Disabilities: Lightweight carbon fiber prosthetics, wheelchair frames.
