Integrally formed aerial platform
An integrally formed aerial support platform is described herein. The aerial support platform is formed from a thermoplastic composite including continuous reinforcement fibers, allowing the aerial support platform to be formed in one piece via compression molding, thereby decreasing the time and effort needed to produce each aerial support platform. An aerial support platform having increased longevity and increased stiffness-to-weight ratio is therefore produced. Furthermore, described is a process for producing an aerial support platform that substantially reduces the amount of volatile organic compound emissions and demonstrates improved recyclability when compared to traditional thermoset composite platforms.
