Vartm Process

In this study, a continuous glass fiber-reinforced composite is manufactured using the vacuum assisted resin transfer molding (VARTM) process. The composite is manufactured from an S-glass fiber acting as reinforcement and an epoxy resin as matrix. Unlike a traditional E-glass fiber reinforcement, S-glass fibers give higher stiffness and provide easier manufacturability due to the value of the refractive index of S-glass lying within the range of refractive indices of the epoxy resin. The epoxy resin is synthesized Epon 826, Epalloy 5200, and hexahydropthalic anhydride and tailored to match refractive indices of the S-glass fibers. After synthesis of the resin, composite panels are manufactured from the synthesized epoxy resin and S-glass fibers with a bi-directional [0°/90°] 8-harness satin weave. VARTM process was utilized to manufacture the composite panels. Composite panels are visually inspected for transparency, and tensile, flexural, and impact testing is performed. Mechanical tests showed consistent results for tensile modulus, tensile strength, flexural modulus, flexural strength, and impact damage resistance.

Ni Powder

In this paper, Ni powder/M-glass fiber reinforced epoxy composite panels with different Ni powders were prepared by mould pressing method, of which the ultrafine Ni powder is prepared by the liquid reduction method. The waveguide method can be used to measure the electromagnetic parameters of the samples in the frequency ranged from 8.2 GHz to 18 GHz. The results show that Ni powders distributed evenly during the M-glass fibers reinforced epoxy layers. The main absorbing mechanism of composite panels is magnetic loss. The absorbing properties of samples increase with the adding of Ni powder contents and the thickness of panels. Based on the theory of the transmission line, the optimization design of Ni powder/ M-glass fiber reinforced epoxy composite has been calculated. When the whole thickness of the composite panels is 4.6mm excepting the Al plate thickness with the absorbing layer of Ni powder/ M-glass fiber reinforced epoxy of 1mm, the whole absorbing properties improve gradually with the increase of frequency ranged from 8.2 GHz to 18GHz and the absolute value of the reflection coefficient R is above 10dB.

Recent research scenario reveals that the amalgamations of micro and nanoceramic fillers into fiber reinforced polymer composites have improved their performances in an excellent manner. In this research work, an investigation was attempted at in analyzing the wear behavior of glass fiber reinforced with epoxy resin using granite powder as a filler material in varying weight percentage ranging from 0-5%. Structural morphology of the prepared laminates was studied using SEM. Epoxy resin which was taken as matrix material was reinforced with a combination of chopped and woven roving mat glass fibers. Pin on disc method was applied for completing the wear test at different constraints of load, sliding distance and velocity for the investigation. Influence of granite powder in the composite was synthesized by calculating the specific wear rate and weight loss occurring at varying speed and normal load were applied on it. On examining by SEM worn surface wear rate of the prepared laminate at 5 wt% of granite provided better wear resistance as compared to other compositions and characterizations of worn surfaces.

Face guards (FGs) are protectors that allow for the rapid and safe return of athletes who are to play after sustaining traumatic facial injuries and orbital fractures. Current FGs require significant thickness to achieve sufficient shock absorption abilities. However, their weight and thickness render the FGs uncomfortable and reduce the field of vision of the athlete, thus hindering their performance. Therefore, thin and lightweight FGs are required. We fabricated FGs using commercial glass fiber-reinforced thermoplastic (GFRTP) and carbon fiber-reinforced thermoplastic (CFRTP) resins to achieve these requirements and investigated their shock absorption abilities through impact testing. The results showed that an FG composed of CFRTP is thinner and lighter than a conventional FG and has sufficient shock absorption ability. The fabrication method of an FG comprising CFRTP is similar to the conventional method. FGs composed of commercial FRTPs exhibit adequate shock absorption abilities and are thinner and lower in weight as compared to conventional FGs.

Short glass fiber-reinforced (SGFR) thermoplastics are used in many industries manufactured by injection molding which is the most common technique for polymeric parts production. Glass fibers are commonly used as the reinforced material with thermoplastics and injection molding. In this paper, a critical plane-based fatigue damage model is proposed for tension–tension or tension–compression fatigue life prediction of SGFR thermoplastics considering fiber orientation and mean stress effects. Temperature and frequency effects were also included by applying the proposed damage model into a general fatigue model. Model predictions are presented and discussed by comparing with the experimental data from the literature.
