INVESTIGATION OF DAMAGE IN COMPOSITE STRUCTURES CAUSED BY SIMULATED LIGHTNING STRIKES

Gang Zhou (Loughborough University) Weiwei Sun (C-Power (Technology) Ltd) Ben Mahy (Loughborough University)

 

A study of the direct effects of lightning strike in both carbon/epoxy and E-glass/epoxy laminates has been carried out. The key damage characteristics are fibre fracture in tufting for carbon/epoxy and extensive delamination for E-glass/epoxy.

PREPARATION AND FLAME RETARDANCY OF POLYURETHANE COMPOSITES USING MICROENCAPSULATION TECHNOLOGY

Wei Jen Chen (China University of Science and Technology) Ming-Yuan Shen (China University of Science and Technology) Chen-Feng Kuan (Far East University) Hsu-Chiang Kuan (Far East University) Jia-Ming Yang (Hung-Kuang University) Chin-lung Chiang (Hungkuang University)

 

In this study, a novel microcapsulated flame retardant was synthesized using in situ polymerization technology. The flame retardancy and thermal properties of the Si-PU/OFAPP composite was higher than that of the Si-PU/APP composite.

THERMAL AND REACTION TO FIRE PROPERTIES OF CFRP UNDER VARIOUS HEAT IMPACT SCENARIOS -SPECIFIC HAZARDS

Sebastian Eibl (Bundeswehr research institute for materials, fuels and lubricants (WIWeB))

 

The work addresses specific dangers originating from CFRP structures under thermal load. It investigates effects of various types of heat loads, starting below the max. operational temperature limit (135°C), up to rapid matrix degradation (ca. 350°C).

DISCRETE DAEM MODEL FOR THE STUDY OF THE KINETICS OF THE THERMAL DEGRADATION OF A LIGNIN NANOPARTICLE-REINFORCED PHENOLIC FOAM

Juan Carlos Domínguez (Complutense University of Madrid) Belén Del Saz-Orozco (Universidad Complutense de Madrid) Mercedes Oliet (Universidad Complutense de Madrid) María Virginia Alonso (Universidad Complutense de Madrid) F. Rodriguez (Complutense University of Madrid) Julián García (Universidad Complutense de Madrid)

 

The main goal of this work is the study of the kinetics of thermal degradation of phenolic and lignin nanoparticle-reinforced phenolic foams, and of the lignin nanoparticles used as reinforcement through a discrete distributed DAEM model.

EFFECT OF MULTI-WALLED CARBON NANOTUBES ON MECHANICAL PROPERTIES OF CARBON FIBER POLYURETHANE FOAM SANDWICH STRUCTURES: OPTIMIZATION OF PARAMETERS USING TAGUCHI’S DESIGN

İdris Gürkan (Istanbul Technical University) Elif Demir (Istanbul Technical University) Hülya Cebeci (Istanbul Technical University)

 

Nanoparticle disperision into polymers is the most critical issue, due to high surface energy of the particles. In present work, carbon nanotubes are dispersed in the rigid polyurethane foam and epoxy resin using different methods.

FABRICATION AND CHARACTERISATION OF POLYURETHANE/SEPIOLITE POLYMER NANOCOMPOSITE FOAMS FOR ENHANCED ENERGY ABSORPTION.

Ellen Pope (University of Bristol) Jeroen van Duijneveldt (University of Bristol) Fabrizio Scarpa (University of Bristol)

 

Sepiolite clay rods with various surface chemistries were dispersed in a polyurethane foam precursor before being foamed up with MDI. Mechanical tests were performed to determine Young's Modulus, energy dissipation and loss factor.
