Composites Part B: Engineering, 2017
Abstract Fiber reinforced thermoplastics are considered as promising candidates to enable the mass production of lightweight components. To assure their structural application, accurate methods to describe their mechanical behavior are mandatory. However, the modeling of the damage behavior of the thermoplastic matrix under multiaxial stress states ...

Applied Composite Materials, 2000
Raman spectroscopy was used to investigate the compressive fragmentation process and the interface behavior in ultra high modulus (UHM) (750 GPa Modulus) pitch-based graphite/polypropylene composites upon cooling from processing temperature to room temperature. It is found that bulging is the primary mechanism of failure in these fibers, and Raman peak

Composites Part B: Engineering, 2017
Abstract The search of more environmentally friendly material is not an end in itself. Such materials must also show competitive mechanical properties, comparative prices and a good adaptation to the manufacture processes. Nowadays, Glass fibers had been traditionally used as reinforcement of polyolefin for mold injected products.

Advanced Materials Research, 2012
Based on the construction application of C50 anti-cracking pumping concrete, the influence of the polypropylene fiber and expansive agent on the concrete was studied. The workability, mechanical property, drying shrinkage and crack resistance of the pumping concrete and their mechanisms were tested.

Frontiers of Structural and Civil Engineering, 2019
Many studies have evaluated the effects of additives such as nano-silica (NS), micro-silica (MS) and polymer fibers on optimizing the mechanical properties of concrete, such as compressive strength. Nowadays, with progress in cement industry provides, it has become possible to produce cement type I with strength classes of 32.5, 42.5, and 52.5 MPa.

Building Acoustics
As urbanization and building densities increase, the need for effective sound and thermal insulation in building design becomes increasingly important. This study investigates the impact of polypropylene fibers and microparticles on the sound and thermal insulation properties of recycled polyurethane foam.

Textile Research Journal
Fabrics with a higher level of inter-yarn friction usually demonstrate better impact resistance, as suggested by various studies on the impact response of ballistics-resistant fabrics. Over the past decade, significant efforts have been made to improve the frictional properties of fabrics, for example, with surface coatings.
