Weakening composite materials to make them tougher
A short summary of Daan Jonas Hottentot Cederløf's thesis "Enhanced damage tolerance of composite materials by multiple delaminations". The DACOMAT project aims to control damage formation and growth in large composite structures. This work directly contributes to both aspects: by material treatment we can control where the damage initiates; by forming multiple delaminations we can increase the laminate’s overall resistance to damage growth.
A Key Innovation award to the DACOMAT project
A resin development within the DACOMAT project has been awarded as Key Innovation. Polynt Composites Norway AS (on behalf of Polynt Group) has been identified as a “Key Innovator” for the DACOMAT innovation titled “Novel chemistries of poly-vinyl ester resins formulations for improving fibre bridging”
Micromechanical model of fiber bridging
A new open publication "A micromechanical model of fiber bridging including effects of large deflections of the bridging fibers", is developed in the DACOMAT project and has now been published in Composite Structures. The new model can be valuable tools for studying the underlying mechanisms of fiber bridging and how to utilize this phenomenon to maximize the fracture resistance and damage tolerance of composite laminates.
A mixed mode cohesive model for FRP laminates incorporating large scale bridging behaviour
New open publication and data to download on: A mixed mode cohesive model for FRP laminates incorporating large scale bridging behaviour. A user defined cohesive material model is implemented in the LS-DYNA finite element code. The model is based on interface properties characterised from DCB specimens loaded with unequal bending moments

Material life cycle-thinking
Our actions affect the environment in ways we may not understand when we decide what products to use and how to use them. What are they made of and how are they made? How do we use them and how do we dispose or recycle them? In the DACOMAT project we use LCA and LCCA to reduce our impacts. Here we explain what they are and why they are important tools.
Bridge in Skien will serve as LCA & LCCA study case in DACOMAT
A new pedestrian bridge is to be constructed in the city of Skien, Norway. The bridge has a liftable midsection to allow ship passage. The liftable section of the bridge will be a composite structure engineered by DACOMAT partner FiReCo. The side spans will be constructed in concrete by Johs Holt. The light composite solution allows the liftable section to be constructed without counter weights that will interrupt the view of the city.
39th Risø International Symposium on Materials Science
3-6th of September 2018 the 39th Risø International Symposium on Materials Science was arranged by DTU Wind at their campus at Risø near Roskilde in Denmark. The topic of the symposium was Fatigue of Composite Materials: Microstructure, mechanics and methods.
Report - LCA database of environmental impacts to inform material selection process
In the DACOMAT project, new composite materials will be manufactured. The first deliverable in the project is a report providing advice on relevant Life-cycle assessment (LCA) data for use by project partners. The deliverable is a database which gives environmental impact data on Global Warming Potential and Embodied Energy (carbon footprint) for materials and processes relevant to the project.
New research into the use of composite materials aims to reduce bridge costs and provide more durable wind turbines
Bridges constructed with fibre reinforced polymers (composites) may become a familiar sight in Europe if a new pan-European research project achieves its objectives. The project also aims to provide more durable and reliable wind turbines.
Fibre-reinforced plastic may reduce the costs of bridges
They are lightweight, strong, and resistant to corrosion and decay. In the future, bridges in Norway could be made of fibre-reinforced plastic elements, which extend their lifespans and reduce life cycle costs.
