OPTIMIZED HYBRID METAL-THERMOPLASTIC COMPOSITE JOINTS USING LASER MICROTEXTURING AS A SURFACE TREATMENT
Pilar Rey Rodríguez (AIMEN Technology Centre) Clara Palleiro Palmou (AIMEN Technology Centre) Nerea Otero Ramudo (AIMEN Technology Centre)
Laser textured aluminium parts were joined to fibre reinforced thermoplastic composite coupons by ultrasonic welding. The best laser microtexture pattern and joint configuration were selected to perform structural hybrid metal-composite joints.
RESEARCH ON THE INTERFERING EFFECT OF METAL INSERTS IN FIBER-REINFORCED-PLASTICS MANUFACTURED BY THE RTM PROCESS
Jonas Wilkening (Karlsruhe Institute of Technology) Florentin Pottmeyer (Institute For Applied Materials IAM-WK) Kay Weidenmann (Karlsruhe Institute of Technology)
This paper aims on the systematic research on the interfering effects of inserts in CFRP parts. The specimens are tested under quasi-static tensile loads, while the load transfer is carried out by the laminate itself instead of the insert.
EFFECT OF DWELL TIME ON THE PROPERTIES OF COMPOSITE MATERIALS
Sanjeev Rao (AerospaceResearch and Innovation Centre) Maryam Al-Kuwaiti (Strata Manufacturing) Vaughan Barber (Strata Manufacturing) A. Abusafieh (Strata Manufacturing) Wesley Cantwell (Khalifa University)
Reserach has been carried out to examine the effect of longer soak time on the mechanical and material properties of the matrix and the composite part.
EFFECT OF REPAIR DESIGN AND SURFACE TREATMENT ON ADHESIVELY BONDED COMPOSITE REPAIRS
Florian Röper (Polymer Competence Center Leoben GmbH) Markus Wolfahrt (Polymer Competence Center Leoben GmbH) Georg Kucher (FACC Operations GmbH) Andreas Bubestinger (FACC Operations GmbH) Gerald Pinter (Montanuniversitaet Leoben)
A combination of corona and wet chemical surface treatment is assessed. Furthermore, the influence of scarf angle, adhesive type and surface treatment on the mechanical performance of adhesively bonded composite repairs is investigated.
RISK ASSESSMENT OF MECHANICAL FAILURE BY DETERMINING PROBABILITY OF FLEXURAL STRENGTH DETERIORATION IN EPOXY- GLASS LAMINATES AFTER LONG-TERM WATER IMPACT
Aneta Krzyzak (Polish Air Force Academy)
The paper presents how the risk of failure by flexural strength test changes depending on the period of water impact, pressure at production of laminates and the type of glass fibre preparation.
EXPERIMENTAL AND NUMERICAL ANALYSIS OF REPAIRED STIFFENED CFRP PANELS UNDER COMPRESSION
Dalong Dong (Shanghai Jiao Tong University) Hai Wang (Shanghai Jiao Tong University) Xiang Zhou (Shanghai Jiao Tong University)
This paper presents an experimental and numerical study on the mechanical behaviors of CFRP stiffened panels containing two types of initial defects with three repair methods i.e. mechanical repair, adhesively bonded repair and scarf patch repair.
EVALUATION OF THE GEOMETRY OF SINGLE-LAP ADHESIVE JOINTS IN COMPOSITE LAMINATES
