ROBUST AND HIGHLY INTERCONNECTED POLYURETHANE DIACRYLATE BASED MACROPOROUS POLYMERS

Qixiang Jiang (University of Vienna) Angelika Menner (University of Vienna) Alexander Bismarck (University of Vienna)

 

Open porous polymers were obtained via polymerising emulsion templated based on polyurethane diacrylate and styrene; the resulting polymer foams (polyHIPEs) were tougher than the polyHIPE based on styrene and divinylbenzene.

MECHANICAL CHARACTERIZATION BASALT AND GLASS FIBER EPOXY COMPOSITE BY THE RING-TYPE TEST SPECIMENS

Mauro Lapena (aSpace and Aeronautic Institute) Gerson Marinucci (IPEN)

 

The aim of this work is to compare mechanical properties between basalt and E-glass rings manufactured by filament winding. Split-disk tensile tests provide reasonably accurate information with regard to the apparent tensile strength.

EFFECTS OF SIZING ON THE MECHANICAL AND ELECTRICAL PROPERTIES OF CARBON FIBERS

Shinn-Shyong Tzeng (Tatung University) Yen-Ju Wang (Tatung University)

 

Effects of sizing on the mechanical and electrical properties of carbon fibers were investigated. Desizing was found to decrease the fiber tensile strength significantly for carbon fibers with surface striations.

RESEARCH ON MELT SPUN PMMA COMPOSITES WITH ALIGNED CARBON FIBERS

Muchao Qu (Friedrich-Alexander University) Dirk Schubert (Friedrich-Alexander University)

 

PMMA/carbon fibers (CF) composite fibers with highly oriented CFs were melt spun, with the concentration of CFs up to 56 vol. %. The percolation threshold of the composite fibers was estimated between 23.96 vol. % and 28.64 vol. %.

MEASUREMENT OF ACOUSTOELASTIC COEFFICIENT ON CARBON FIBER REINFORCED POLYMER COMPOSITES USING LCR WAVES

Wei Wang (Harbin Institute of Technology) Yumin Zhang (Harbin Institute of Technology) Yufeng Zhou (Harbin Institute of Technology)

 

Using critically refracted longitudinal wave, we acquired the relations between variation of the time-of-flight and applied stress along different direction, which is meaningful for accurate measurement of residual stress in CFRP composites.

MECHANICAL PROPERTIES OF PA6 COMPOSITES REINFORCED WITH SURFACE-TREATED PITCH CARBON FIBERS

Jin Woo Yi (Korea Institute of Materials Science) Wonoh Lee (Korea Institute of Materials Science) Dong Gi Seong (Korea Institute of Materials Science) Sang Woo Kim (Korea Institute of Materials Science) Moon Kwang Um (Korea Institute of Materials Science)

 

Polymer composites were successfully fabricated by a film infusion process with PA6 as matrix and phenoxy resin-coated pCFs as reinforcement. ILSS show that interfacial adhesion between PA6 and the carbon fiber can be improved by the phenoxy resins.
