Title:
DEGRADABLE COMPOSITE MATERIAL, FAN BLADE, AND METHOD FOR PREPARING SAME
Document Type and Number:
WIPO Patent Application WO/2023/184762
Kind Code:
A1
Abstract:
Disclosed are a degradable composite material, a fan blade, and a method for preparing same. The degradable composite material of the present invention comprises, in percentages by mass, 30-40% of a degradable epoxy resin composition, 45-55% of a fiber raw material, 0-20% of a core material, and 0-10% of an epoxy structural adhesive. The degradable epoxy resin composition contains degradable modified resin. The present invention adopts the degradable epoxy resin as a structural layer, and the prepared wind turbine blade has excellent mechanical properties and meets the blade design requirements and the industry EHS specification. The present invention adopts the degradable epoxy resin as the structural layer, which requires no additional adaptation when used by a user without changing existing process parameters; due to the use of the degradable epoxy resin to replace the current epoxy resin, the prepared composite material part can be degraded and separated under proper conditions, and the recycled resin liquid and fiber raw materials can be reused, thereby achieving a green circular economy.
