Through the Microscope Fracture Analysis of Long-Fiber Reinforced Thermoplastics

From Ticona Engineering Polymers

Classic fracture analysis of unfilled plastics has welldefined
and well-documented methods for determining what
happened to broken parts. However, introducing long-fibers
into the picture obscures many of the usual clues, and while
there are excellent materials available on fracture analysis
in general, information appears scarce regarding these
materials. Microscopy is a powerful tool in this area when
combined with careful observation and deductive reasoning.
This paper discusses helpful clues that the microscope has
yielded in our laboratory for fracture analysis of long-fiber
reinforced thermoplastic parts

Products & Services
Resins and Compounds
Resins and compounds are used for shape fabrication or bond formation. Types include adhesive, casting, and leveling resins; caulk and grout; and sealants and thread lockers.
Monomers, Intermediates, and Base Polymers
Monomers, intermediates, and base polymers are starting raw materials or binders for the production of compounded resins, plastics and elastomers, paints or organic coatings, adhesives and sealants;
Thermoplastics and Thermoplastic Materials
Thermoplastics and thermoplastic materials soften when heated and harden when cooled. They can withstand many heating and cooling cycles and are often suitable for recycling.
Specialty Polymers and Resins
Specialty polymers and resins are proprietary polymers, resins, monomers and intermediates. They include products that are based on proprietary curing technologies or chemistries, or that are designed for specialized applications.
Molding Compounds and Resins
Molding compounds and resins are industrial plastics and polymers that are suitable for forming. They are used in injection molding, compression molding, reaction injection molding (RIM), resin transfer molding (RTM), and blow molding.
