The benefits of wood as a structural material have long been utilized in marine applications, including fender systems used to protect docking structures and vessels during vessel berthing. In the past, preservative-treated timber has been a commonly used material for structural elements in fender systems.Wood plastic composite panel Due to degradation from marine borers and the placement of environmental restrictions on the use of preservative-treated wood, an alternative material is sought to replace the wood members. The U.S. Office of Naval Research funded a project at Washington State University to investigate the use of wood-plastic composite (WPC) lumber as an alternative to the traditional timber members. The benefits of WPC lumber include resistance to marine borers and rot, reduced environmental impact due to the absence of preservative treatments, and members can be produced in hollow net sections. In addition, as manufacturing processes and material composition are refined, reduced production costs will enable the WPC material to become a viable option for many structural applications.
The information presented in this thesis is part of an ongoing comprehensive research project being conducted at Washington State University to develop wood-based composite members for waterfront structures.[url=http://www.woodplasticcompositepanel.com/project-case/wpc-applications-in-landscape-advantages]wood plastic composite applications[/url] in landscape advantages The project consists of four major components: materials development, structural analysis and design, recycling, and a demonstration component for validation of the technology and products.
The objectives of the structural design and analysis component are to support the materials development by providing estimates for structural demand, identifying components of existing waterfront facilities as targets for application of composite materials, establishing design criteria, verifying through testing component performance,Recycled wood-plastic composite decking product decking and facilitating the implementation of both drop-in replacements and complete waterfront systems utilizing engineered wood-plastic composites. The specific contributions to these objectives reported in this thesis include conducting tests of prototype components to characterize performance, developing standard criteria for component evaluation and assignment of design values, providing guidance for design of specific demonstration applications, and developing analytical models for understanding the behavior of WPC structural members.
