Description

Technical field The present invention relates a composite skateboard deck and a method for manufacturing the composite skateboard deck. The invention also relates to a skateboard with a composite skateboard deck and a method for manufacturing a composite skateboard deck. Background Skateboard decks of traditional wooden skateboards are composed of stacked wood layers combined together using adhesive bond. Such wooden skateboards are cheap to produce, but due to construction they wear, chip, break, and lose performance very easily, especially when being worked hard by an experienced user. Composite skateboards have been introduced to skateboard deck constructions for decades ago, these skateboards include both fiber reinforcement layers and edges manufactured to withstand impact. On such constructions skateboard deck edges have utilized reinforcements or fills. Hybrid skateboards composed of plywood and fiber reinforcement layers have been in the market since 1980s. Hybrid skateboard decks could include wood, fiber reinforcement layers and non-wood parts, for example, plastic parts. US 20190091551 discloses an electric-powered personal transportation vehicle featuring a composite board designed to support the user's weight. The vehicle includes one or more wheels driven by electric motors, which are powered by one or more batteries. The composite board is made up of a heterogeneous mix of individual components, including a spine made of hardwood material and sides made of vibration-dampening, high-density foam. US 10137357 discloses a skateboard deck is designed to be lighter, stronger, and more resilient overall. Composite laminate layers, including carbon fiber, enhance the deck's strength and performance by reducing weight and thickness while boosting resilience. High-strength tip fills and side edges prevent chipping and delamination, with composite layers inlaid for added protection. These features safeguard the deck against abrasion, chipping, and delamination.
