The effect of fiber type and hybridization on the repeated impact strength was investigated experimentally using six high-performance concrete mixtures reinforced with a 2.5% volume fraction. types considered in this study included short steel fibers (SF) 6 mm length, long SF 15 polypropylene (PP) fibers. test conducted specially made automatic testing machine following setup recommendations AC...

With the improvement of social and economic level, green construction sustainable development have become main directions industry, disadvantages limitations traditional wooden template steel gradually been exposed, which cannot meet industry in new era. The materials structural forms formwork has a problem that attracted much attention industry. EANTE’s composite material adopts self-developed...

Each year about 50 Million tons polymer is processed to fibers worldwide [1]. Polymeric fibers are manufactured into all sorts of daily as well as industrial goods [2, 3]. The most prominent materials are thermoplastic among which poly(ethylene terephtalat) (PET), polyamides (PA) and polypropylene (PP) make up the largest fraction [4]. Other thermoplastic polymers such as poly(vinylidene fluori...

Mortars containing carbon, polyethylene, and stainless steel fibers at the same volume fraction and with similar fiber diameters were compared in terms of tensile, compressive, and flexural properties. Carbon fibers, though having the lowest tensile modulus, stren[?th, and elongation at break among the fiber types, [?ave mortar of the highest tensile strenf?th and lowest cost; polyethylene fibe...

In this paper we investigate the transient shear rheology of a polypropylene containing long fibers (2.75 to 11 mm, L/D > 150) and short fibers (1 mm, L/D < 50). The objectives of this work are to determine the relationship between stress growth and relaxation behavior of fiber orientation and determine the feasibility of extending Doi’s theory for the rheology of rod-like molecules to fiber re...
