Sensitivity to crack propagation in flax fiber-reinforced polypropylene (PP) composites has been examined on SEN-T specimens. The sound waves that arise due to loading have been investigated with the acoustic emission method. Linear functional relationship has been revealed between the number of acoustic events that occur during loading and the fracture toughness. It has also been observed that...

Fiber reinforced composites (FRCs) are more and more widely applied in dentistry to substitute for metallic restorations: periodontal splints, fixed partial dentures, endodontic posts, orthodontic appliances, and some other indirect restorations. In general in FRCs, the fiber reinforcement provides the composite structure with better biomechanical performance due to their superior properties in...

The knowledge of load bearing characteristics and failure of material is very important for mechanical engineers. Various metallic, non metallic and composite materials are used in different application. In view of this, the main objective of the present work is to analyze the influence of Aluminum Oxide filler on Fracture Toughness properties of Chopped Strand Mat (CSM) E-Glass Fiber reinforce...

Natural fibers are receiving considerable attention as substitutes for synthetic fiber reinforcements such as glass in polymer due to their low density, low cost, acceptable specific strength, reduced tool wear and respiratory irritation and renewable resources. The fibers are not uniformly distributed in the randomly oriented fiber reinforced hybrid composites due to manual lay-up and fibers a...

In this paper, an experimental investigation on ultrasonic welding of polyamide composites reinforced with glass fiber has been carried out. The effect of ultrasonic welding parameters, such as welding time, air pressure, hold time and the amount of glass fiber in the composite on tensile strength of weld joints were determined using response surface methodology. This methodology was applied fo...

In this research work, impact strength of untreated, alkali treated, potassium permanganate treated, benzoyl chloride treated and acrylic acid treated areca fiber reinforced epoxy composites were studied under 40%, 50%, 60% and 70% fiber loadings. Impact strength increased with increase in fiber loading up to 60% and then showed a decline for all untreated and chemically treated areca fiber rei...

Magnesium phosphate cement (MPC) has been proven to be a very good repair material for deteriorated concrete structures. It has excellent adhesion performance, leading to high bonding strength with old concrete substrates. This paper presents an experimental study into the properties of MPC binder as the matrix of carbon fiber sheets to form fiber-reinforced inorganic polymer (FRIP) composites....

Environmental awareness today motivates the researchers, worldwide on the studies of natural fiber reinforced polymer composite and cost effective option to synthetic fiber reinforced composites. The availability of natural fibers and ease of manufacturing have tempted researchers to try locally available inexpensive fibers and to study their feasibility of reinforcement purposes and to what ex...

Machining of glass fiber reinforced plastic composite materials is an active area of research in current manufacturing processes. Achieving an improved surface finish is of high priority while machining the polymer based plastics composites due to the poor machinability of glass fibers. The present work deals with the study and development of a surface roughness prediction model for machining u...

Polymeric materials reinforced with synthetic fibers like glass, carbon, and aramid provide advantage of high stiffness and strength to weight ratio as compared to conventional materials like wood, concrete etc. Despite of these favours modern researches are going on in the field of natural composites because of low initial cost and availability of ease. I the light of these the present experim...
