The application of flax fiber is vast in the various fields in the world, the well-known in the area of as textiles many of the countries they used the flax fiber mixture with linen, traditionally used for making of bed sheets, underclothes and table linen. The specific properties of flax fiber responsible for the potential platform to next-generation structural applications in automobile and other consumer works. Due to its mechanical properties, flax fiber composites possess good strength and durability. In this review paper, the various proportion on evaluation of work done to know about the amount of research undergone with flax fiber composite in various fields. From this review paper, the utilization of flax fiber has gap in variety of applications in various fields. To identify the research gap and its utilization, quantum of work to be done in the all of the areas was analyzed in that 36% of work done on mechanical property, 30% in novel performance work like simulation and model analysis, 18% of work going on marine, aeronautical related applications and only 16% work carried out in structural related applications using flax fiber composite, flax fiber composite products are potentially used because of their lighter weight and lower cost. Most of the automobile components are replaced by flax fiber composite, these composite components are sound in the capability to reduce the weight for fuel efficiency. Other developing market applications such as tiles, marine piers and flower pots are now a day manufactured from flax fiber composite. In the future, the flax fiber will reduce the utilization of synthetic fiber, by producing an eco-friendly environment in all type of products, wherever replacement is possible with some synergic property.

Glass fiber (GF) and mica (MC) filled polycarbonate (PC) composites were fabricated using extrusion process due to considerable applications of PC as recyclable and thermo-stable material in mainly medical, packaging and transportation fields. Tensile, hardness and impact tests, differential scanning calorimetry (DSC) and thermal gravimetric analysis (TGA), melt flow index (MFI) test and scanning electron microscopy (SEM) findings were reported. Mechanical test results show that tensile strength and modulus are improved for higher GF and lower MC contents. The necking behavior of PC disappear after MC and GF inclusions due to the reduction of ductility. Impact strength of PC is reduced with both additions of GF and MC. Glass transition temperatures (Tg) of PC and relevant composites were estimated by the help of DSC analysis. Tg of PC hifts to higher temperatures by the addition of GF. According to TGA results, GF and MC additions cause remarkable increase in thermal stability of PC. MFI of PC extends up to higher values with increase in GF concentration. SEM analysis reveals that GF and MC display nonhomogeneous dispersion for their high loading ratios. Individual inclusions of additives yield higher mechanical and thermal performance than hybrid composites.

Hybrid composites find applications in many advanced fields that include aerospace and armour due to their high specific strength and high energy absorption capacity. The present study has attempted to develop cost effective E and S2 glass based hybrid composites for armour applications in order to get advantages of both fibres i.e superior impact properties at reduced cost. Three hybrid composites based on E glass and S2 glass in the volume ratios of 75:25, 50:50 and 25:75 were fabricated using epoxy matrix. Low velocity impact (60-110 J energy) experiments using instrumented drop tower on 2 mm thickness laminates show that composites perform better when impacted on E glass strike face than on S2 glass strike face. Hybrid composite made of 25% E glass and 75 % S2 glass (ES 25-75) has shown equal performance to that of 100 % S2 glass/epoxy (S 100) laminate. Ballistic evaluation on 6 mm thick laminates against 7.62 mm mild steel projectile also prove that the performance of hybrid composites increases with increase in S2 glass content and ES 25-75 composite performs similar to S 100 laminate in terms of energy absorption as well as damage volume.
