Case Study: Wind Turbine Blade GRP Bonding
The Client
A wind turbine manufacturer was encountering difficulties with bonding and fitting wind turbine components onto the turbine blades.
The Problem
Specifically, the winglets, vortex generators and serrations required a good bonding solution that would match the following operating conditions:
- High humidity – 90% RH
- Low temperatures – 0°C
- Up to 4mm gap filling
- Good weathering/ageing resistance
- Heating blanket accelerated curing
- GRP bonding
The Solution
Huntsman representatives from Antala worked with the manufacturer and determined Huntsman Araldite 2015-1 as the ideal solution for this application.
Araldite 2015-1 is a two-component, room-temperature curing epoxy paste adhesive which provides a resilient bond. It is thixotropic and non-sagging up to 10mm in thickness. In addition, it provides great resistance to weathering, humidity and a wide temperature range. This adhesive has the capability to bond a wide variety of materials including GRP, SMC, Ferrous Metal, Glass Fibre Reinforced Polymer, Non-Ferrous Metal, Ceramic, Glass, Rubber and Wood. It is also Lloyds Register approved.
The Benefits
As a result of using Araldite 2015-1, the manufacturer was able to achieve:
- Strong, resilient GRP bonding of wind turbine components to turbine blade
- Effective gap-filling
- Great weathering and environmental resistance
- Operation in low temperatures
- Operation in high humidity
- Lloyds Register approval
Araldite 2015-1 served as the ideal solution for bonding wind turbine components to the turbine blades for this manufacturer.
