Cyclic compression test was performed on square braided fabric and the effects of the type of fiber bundle were examined for aramid and glass square braided fabrics. Moreover, the strength of the fiber bundles from the square braided fabric after cyclic compression loading was investigated with tensile testing of fiber bundles. It was found that the strength of the glass fiber bundle was decreased with the increase of compression cycle, whereas the strength of aramid fiber bundle was not decreased. The decrease in strength of glass fiber bundle caused an increase in cumulative deformation with compression cycle.

Continuous fiber-reinforced thermoplastic (c-FRTP) has received attention for reducing automobile weight. Hollow molded parts made by pultrusion molding of braided composites may improve the performance and reduce the weight of automotive parts. However, pultrusion molding of braided composites suffers from productivity problems. This research aimed to increase the productivity of pultrusion molding of braided fabrics to facilitate its practical application. The effects of the fiber intermediate fabrication method and the resin melt viscosity on the impregnation and mechanical properties of the composite were investigated. Glass fiber and polyamide 66 (PA66) were used as the fiber intermediates. Two types of fiber intermediates were used, one with interlace processing and one with the fibers lined up. PA66 fibers with high and low viscosity were used. A correlation was found between impregnation properties and mechanical properties of the molded products, which improved as the unimpregnated ratio decreased. Detailed observations revealed that impregnation of PA66 resin into glass fiber bundles started from interlaced points in the fiber intermediates introduced by interlace processing. Furthermore, low-viscosity PA66 resin had higher fluidity, which better promoted impregnation into glass fiber bundles. These results clarify design guidelines for fiber intermediates to realize better mechanical properties and shorter molding cycles.

Resin Curing

Because of good mechanical properties of the fiber composites, the fiber bundles without the resin curing process and with the features of high modulus, high strength and good performance of creasing resistance etc, can be used in prestressed structures. According to the strength properties of the fiber, the tensile characteristic function of the fiber bundles is derived. The tensile test is designed and the parameters of the weibull distribution are estimated based on the result of the test. The ultimate strength of fiber is inversely proportional to the length of fiber. The calculating strength should be reduced in design, because the discreteness of the strength of the fiber bundle in test is much larger than the calculated values.

Knitted Fabric

In this paper, mechanical properties of notched weft-knitted glass fiber stiffness and strength of knitted composite plates were determined. The knitted fabric composite plates was fabricated for various thickness by using 360 grams per m2 glass fiber woven mat with the 10: 1 ratio of LY 556 epoxy resin and HY 951 hardener. Thickness of plates 7, 12 and 13.5mm consists of 22, 41 and 49 layers. However, to date, no comparative study has been made to evaluate the suitability of different modeling schemes to predict the stiffness and strength properties of knitted fabric composites. Further, a comparative study of tensile and compression test is carried out based on a plain weft knitted glass fiber reinforced composites. The compression test having the ultimate stress of maximum at 12 mm thick plate and tensile test the ultimate stress was maximum at 13.5 mm thick plate.Specimens were prepared for two configurations CWC and WCW. The stiffness and strength data is plotted with respect to load vs. displacement curves. Mechanical properties of variable thickness glass fiber composites stiffness and strength depends on the material size as well as thickness of the plate. The test result in stiffness and strength is predicted by using the experimental data.

Flaxseed plants are widely grown globally due to the beneficial seed oil derivatives for human and animal consumption and other industrial uses. However, plentiful flaxseed straws are annually burnt after the harvesting of seeds, lacking utilization of the abundant flaxseed fibers, resulting in wastage of a valuable fiber resource and drastic increase in environmental pollution. In this study, initially the chemical composition and mechanical property of flaxseed fiber bundle were investigated, which resulted as 40.11% cellulose, 28.27% hemi-cellulose, 15.08% lignin, 6.3% pectin, 3.1% wax, and the tensile strength of 1.14 cN/dTex. The surface modification treatment was carried out with concentrations of 10 g/L and 20 g/L sodium hydroxide (NaOH). Later, flaxseed fiber bundles reinforced Polybutylene Succinate (PBS) resin composites were fabricated by thermal compression method. The tensile strength of untreated flaxseed fiber bundle/PBS composites was 78.2 MPa, while the flexural strength of 20 g/L NaOH treated flaxseed fiber bundle/PBS composites showed 84% increment from 26.70 MPa to 49.16 MPa. The scanning electron microscopy (SEM) images revealed significantly rougher surface morphology and stronger interfacial bonding of the alkali treated fiber bundles with matrix. The good mechanical properties observed demonstrated the absolute potential of resultant composites reinforced by flaxseed fiber bundles for utilization in the civil and industrial applications.
