The FRP materials can be divided into FRTP( fiber reinforced thermoplastic plastic) and FRSP( fiber reinforced thermoset plastic) according to the resin materials. As a new kind of composite, FRTP attracts people. s attention for the characteristics of light weight, durability, no environmental pollution and reshaping. According to the characteristics of FRTP, we compare the impregnation and moldinging process of FRTP materials and the physical properties of FRTP and FRSP. We study the FRTP laminates products for civil engineering and its mechanical properties and the application situation at home and abroad. Some problem to be solved are also presented.

Civil Engineering Material is one of the main special courses offered to undergraduate students whose major is Civil Engineering. It aims to let students know major civil engineering materials, their physical properties, mechanical properties, how they are used in construction, how they are tested in the lab, and their strength characteristics-information, so that they can solve problems arising from civil construction. Rapid development in civil engineering material requires construction of this course, which could keep the teaching content up-to-date with current situations. This paper analyzed the current conditions of this course and aims for construction and then describes a construction plan, including revision of the teaching content, improvement of teaching methods and class mode, compiling of test database and exercise database.

Dry Shrinkage

Dry shrinkage and brittleness are outstanding problems with the concrete in road bridges. However, the road bridge concrete has not been systematically studied. No research has fully considered the influence of age on the physical-mechanical properties of road bridge concrete. There are few reports on how the green fiber dosage affects road bridge concrete. This paper analyzes the physical properties and durability of green fiber-reinforced concrete for road bridges (RBGFRC). Firstly, calculation methods were provided for physical-mechanical properties of RBGFRC, such as crack resistance, shear capacity of oblique section, and bending capacity of normal section. Next, the physical-mechanical properties of RBGFRC were investigated in terms of flexural strength, compressive strength, splitting tensile strength, and early cracking strength; the durability of the material was discussed from three aspects: carbonation resistance, resistance to freeze-thaw cycles, and porosity. Experimental results verify the good physical properties and durability of RBGFRC. The research provides a reference for applying RBGFRC in other scenarios.

High Strength Fiber

Concrete, one of the most universally accepted construction material, exhibits higher values of compressive strength, but the same cannot be said in terms of its tensile strength. This is the prime explanation for the setback of this construction material, to be used in place of achieving a higher tensile strength. Different endeavors have been made to improve the overall tensile strength of concrete by using diverse materials. These materials were used either as a form of replacement of its main constituents, or simply as an addition to the other constituents. Out of all such materials, the use of different types of fibers, added a definite proportion of tensile strength without actually altering the configuration of the concrete blocks to a larger extent. Also, in some cases the density of the concrete is a one of the influencing parameters in structural elements and this study is based on the optimization of fibers as a replacement of the Ordinary Portland cement (OPC) along with the use of different industrial waste by products i.e., mineral admixtures and also the light weight aggregates in order to reduce the self weight of the concrete. In this study, an attempt will be made to investigate the mechanical properties of M60 grade high strength fiber reinforced light weight aggregate concrete.

No-fine concrete (NFC) is cellular concrete and it’s light weight concrete produced with the exclusion of sand from the concrete. This study includes the mechanical properties of lightweight reinforced by steel fiber, containing different proportions of steel fiber. This study was done using number of tests. These tests were density, compressive strength, flexural strength and absorption. These tests of the molds at different curing time. The results of tests that implication of fiber to No. fine concrete did not affect significantly on the compressive strength, While the flexural strength were gets better. Results explained that, the flexural strength of (1%) fiber No- fine concrete molds are four times that of the reference molds in age 28 days. The growing in flexural strength for fiber reinforced mixes with fiber by vol. (0.5%, 0.75%, 1%) were (78%, 132%, 286%) respectively at age of 28 days.

Fiber Matrix

The mechanical properties of fiber-reinforced composites are directly related to the nature of the fiber-matrix bond. Fracture toughness is improved when debonding, crack deflection, and fiber pull-out occur which in turn depend on a weak interfacial bond. The interfacial characteristics of fiber-reinforced ceramics can be altered by applying thin coatings to the fibers prior to composite fabrication. In a previous study, Lowden and co-workers coated Nicalon fibers (Nippon Carbon Company) with silicon and carbon prior to chemical vapor infiltration with SiC and determined the influence of interfacial frictional stress on fracture phenomena. They found that the silicon-coated Nicalon fiber-reinforced SiC had low flexure strengths and brittle fracture whereas the composites containing carbon coated fibers exhibited improved strength and fracture toughness. In this study, coatings of boron or BN were applied to Nicalon fibers via chemical vapor deposition (CVD) and the fibers were subsequently incorporated in a SiC matrix. The fiber-matrix interfaces were characterized using transmission and scanning electron microscopy (TEM and SEM). Mechanical properties were determined and compared to those obtained for uncoated Nicalon fiber-reinforced SiC.

This study investigated the combine effect of 0.2 % drink cans and steel fibers with volume fractions of 0%, 0.5%, 1%, 1.5%, 2%, 2.5% and 3% to the mechanical properties and impact resistance of concrete. Hooked-end steel fiber with 30 mm and 0.75 mm length and diameter, respectively was selected for this study.  The drinks cans fiber were twisted manually in order to increase friction between fiber and concrete. The results of the experiment showed that the combination of steel fibers and drink cans fibers improved the strength performance of concrete, especially the compressive strength, flexural strength and indirect tensile strength. The results of the experiment showed that the combination of steel fibers and drink cans fibers improved the compressive strength, flexural strength and indirect tensile strength by 2.3, 7, and 2 times as compare to batch 1, respectively. Moreover, the impact resistance of fiber reinforced concrete has increase by 7 times as compared to non-fiber concretes. Moreover, the impact resistance of fiber reinforced concrete consistently gave better results as compared to non-fiber concretes. The fiber reinforced concrete turned more ductile as the dosage of fibers was increased and ductility started to decrease slightly after optimum fiber dosage was reached. It was found that concrete with combination of 2% steel and 0.2% drink cans fibers showed the highest compressive, split tensile, flexural as well as impact strength.
