Glass Fiber Reinforced

Automotive and industrial design companies have profusely used commodity materials like glass fiber-reinforced polypropylene. These materials show advantageous ratios between cost and mechanical properties, but poor environmental yields. Natural fibers have been tested as replacements of glass fibers, obtaining noticeable tensile strengths, but being unable to reach the strength of glass fiber-reinforced composites. In this paper, polyamide 6 is proposed as a matrix for cellulosic fiber-based composites. A variety of fibers were tensile tested, in order to evaluate the creation of a strong interphase. The results show that, with a bleached hardwood fiber-reinforced polyamide 6 composite, it is possible to obtain tensile strengths higher than glass-fiber-reinforced polyolefin. The obtained composites show the existence of a strong interphase, allowing us to take advantage of the strengthening capabilities of such cellulosic reinforcements. These materials show advantageous mechanical properties, while being recyclable and partially renewable.

The developments in the field of composite materials are phenomenal. The use of natural fibers in the field of composite material is gaining importance. This is due to the advantages of natural fibers: they are eco-friendly, easily available, non-abrasive and cost effective. The combination of natural fiber with Glass fibers is used widely in many applications. In the current investigation Banana – Bamboo – Glass fiber reinforced composites is fabricated by Hand – Layup technique with varying fiber orientation and is tested for its tensile strength and the combination that would yield the best tensile strength is identified by using Taguchi Method.

Polypropylene (PP) including a type of plastic which ranks second on the most number of types of plastic waste after the type of High Density Polyethylene (HDPE). Glass fibers have superior mechanical properties of natural fibers. Because it has good mechanical properties, glass fibers currently plays an important role in the use of composite reinforcement. Mechanical properties of glass fiber owned and PP waste in environmental conditions that more conditions, it can be utilized as a composite reinforcement and matrix materials. This research was conducted by of injection molding method. The comparison between the volume fraction of the glass fiber matrix of type PP plastic waste with variation 0% fibers 100% matrixs, 10% fibers 90% matrixs, 20% fibers 80% matrixs, 30% fibers 70% matrixs, 40% fibers 60% matrixs, and 50 % fibers 50% matrixs. The optimum conditions obtained in this study was the comparison of variation occurs in 50% fibers volume fractions of 50% matrixs were: tensile stress was 24.30 N/mm2, tensile strain was 13.60%.

Pultruded Composites

In this paper, glass fiber-reinforced polyamide-6 (PA-6) composites with up to 70 wt% fiber contents were successfully manufactured using a pultrusion process, utilizing the anionic polymerization of caprolactam (a monomer of PA-6). A novel thermoplastic reaction injection pultrusion test line was developed with a specifically designed injection chamber to achieve complete impregnation of fiber bundles and high speed pultrusion. Process parameters like temperature of injection chamber, temperature of pultrusion die, and pultrusion speed were studied and optimized. The effects of die temperature on the crystallinity, melting point, and mechanical properties of the pultruded composites were also evaluated. The pultruded composites exhibited the highest flexural strength and flexural modulus, reaching 1061 MPa and 38,384 MPa, respectively. Then, effects of fiber contents on the density, heat distortion temperature, and mechanical properties of the composites were analyzed. The scanning electron microscope analysis showed the great interfacial adhesion between fibers and matrix at 180 °C, which greatly improved the mechanical properties of the composites. The thermoplastic reaction injection pultrusion in this paper provided an alternative for the preparation of thermoplastic composites with high fiber content.

AbstractA lab scale structural reaction injection molding (S-RIM) piece of equipment was designed and used to fabricate glass fiber reinforced polydicyclopentadiene (p-DCPD) composites for three different fiber contents. In order to obtain information regarding the optimal process temperature (>80°C) and the curing time (<30 s), differential scanning calorimetry (DSC) was used to investigate the curing behavior of DCPD resin under isothermal conditions. Further, a norbornene-based silane treatment was used to improve the interfacial adhesion between the glass fibers and DCPD as confirmed by the micro-droplet pull-out test and scanning electron microscopy (SEM). Fabrication of glass fiber/p-DCPD composites with improved mechanical properties was carried out based on the optimized process conditions and surface treatment of glass fiber.
