“…Figure 5 a shows the universal testing machine used to test the bending strength. Referring to GB/T 1449-2005 “Experimental method for bending properties of fibre-reinforced plastics” [ 30 , 31 ], ten 2.5-cm-wide and 6-cm-long samples of the composite were cut along the warp and weft direction of the composite, and the bending strength of the composite was tested using a universal testing machine (MTS Industrial Systems Co., Ltd. model Landmark 370.25) (American). The average bending strength was calculated from the data.…”

Glass fibre-reinforced polyphenylene sulphide composites were prepared by hot-pressing glass fibre fabrics and polyphenylene sulphide resins. The effects of different polyphenylene sulphide resin forms on the properties of the composites were investigated using scanning electron microscopy, dynamic mechanical analyser, pendulum impact tester and universal testing machine. The results showed that different polyphenylene sulphide resin forms had nearly no effect on the glass transition temperature of the composites, which are all located at about 100 ℃. Compared with other polyphenylene sulphide composites, the bending strength of polyphenylene sulphide film composites was the highest, reaching 314.58 MPa, and the impact strength of polyphenylene sulphide particle composites was the highest, reaching 245.4 KJ/m2. The bending strength and impact strength were calculated using a standard fraction, and the highest standard fraction was obtained when the ratio of polyphenylene sulphide film to particle was 1:2. The impact strength and bending strength could be obtained. The impact strength reached 229.8 KJ/m2, and the bending strength reached 284.16 MPa.

“…The calculation of flexural strength is in referenced to GB/T 1449–2005 , as shown below:

σ_{normalf} = \frac{3 P l}{2 b h^{2}},

where σ f is the bending strength, the unit is MPa; the P is the maximum load, the unit is N; the l is the span, the unit is mm; the h is the sample thickness, the unit is mm; and the b is the sample width, the unit is mm.…”

Chopped carbon fibers with different dispersion types (colony type and uniform type) and area densities were inserted at sandwich beams, consisting of a PVC foam core covered with two glass fiber/epoxy composite face sheets. The effects of this reinforcement on the interfacial bonding between PVC foam core and glass fiber face sheets were evaluated. Their mechanical properties were measured by three-point-bending and Charpy impact tests. Their structures after mechanical failure were observed by scanning electron microscopy. Compared with the beam without interfacial reinforcement, the bending strength, energy absorption, and impact strength after interfacial reinforcement using 20 g/m 2 uniform chopped fibers increased by up to 109%, 184%, and 47%, respectively, surpassing those of other chopped fiber mats. The weight percentage of carbon fibers/sandwich structure was less than 1%, so the chopped carbon fiber interleave had both cost effectiveness and outstanding structural performance. The improvement of interlayer toughness can mainly be attributed to the fiber bridging structure and the interlayer strength. POLYM. COMPOS., 00:000-000, FIG. 7.

Ply splicing design is a crucial technology to realize the precise manufacturing of woven composite components with various complex shapes. This paper reports two ways of splicing, inter-layer splicing, and in-plane splicing. Two factors affecting the tensile properties of carbon fiber/epoxy laminated woven composites with ply splicing are discussed, including the number of continuous fabric layers on the surface and in-plane splicing spacing. The deterioration of the composites induced during the tensile test is characterized by acoustic emission and digital image correlation. The results reveal that the damage of the laminated woven composites with ply splicing occurs mainly at the butt jointing location and leads to fracture failure. Ply splicing has little effect on the tensile modulus of the composites. The tensile modulus is slightly reduced between 2% and 5%. But ply splicing has a more significant effect on its tensile strength. The total number of continuous fabric layers at the splice position approximately determines the strength retention ratio. The more the number of continuous fabric layers on the surface are, the higher the tensile strength of the composites. When the number of continuous fabric layers on the surface is three layers, the tensile strength retention ratio reaches 69%. The larger the splicing spacing is, the better the tensile properties of the composites. When the splicing spacing is increased to 30 mm, the tensile strength retention ratio reaches 77%.
