Composite materials not only used for structural applications but also in various other applications such as automobile, aerospace, marine, etc. This work describes an experimental mechanical characterization campaign on composite made out of unidirectional Basalt raw with 8 layers. The strength of the material is observed by performing mechanical tests. A core material is introduced in combination with basalt to check the mechanical properties of raw basalt with core as ingredient. In addition to that the influence of core on the strength and thickness of the material is also evaluated by knowing the percentage improvements in strength were the cost of the material also reduces due to the addition of core material. The work has used raw materials from commercial catalogues with no further modification. Compression mould is the manufacturing method used to prepare the sample. After mould process the sample is tailored to ASTM standards for testing Key Words: Compression mould, Mechanical properties, Basalt, Core material. 1.INTRODUCTION The ever growing request of lighter materials used in high speed train, ships, spacecraft and so on, is increasing more and more and the designers are challenged in the field of design and construction of composite materials. A crucial problem, which design engineers are facing in the aerospace industry, is how to attain better design ideas with the consideration of mechanical enactment and industrial cost. The development and application of original, efficient composite structure in an extensive range of industries are inspired by the continuing demands for reduced physical weight, superior effectiveness and enhanced performance. Composite structures are becoming a suitable alternative to metals in several industrial applications particularly for mass carriage where weight reduction is one of the key issues in design factors, owing to their superior advantages of specific mechanical properties and corrosion resistance. To build structures where the weight is a main concern, composite materials are predictably used. Composite structure with less amount of weight, in order to save energy, is primordial for all varieties of transportation industries such as aircraft, trains and cars ( Zinno et al. 2010). Nowadays, in the transportation area and particularly in aerospace machineries, the use of improved lightweight constructions is very common. The first use of composite structure in military aircraft was in the 1960s and then in the 1970s, it was used in civil aircrafts. Nevertheless, the manufacturers of civil aircraft were slow to use the composite structure for primary structural application in aircraft until the 2000s. In the 21st century, owing to their exceptional mechanical behaviors and multifunctional uses, composite materials are reflected as the most favorable multifunctional configuration resources. They meet design and qualifications necessities and provide notable weight benefits as well as substantial cost diminutions. Fiber reinforced plastic composite structures are extra outstanding for constructing ultra-lightweight multifunctional configurations mainly for spacecraft (Katnam et al. 2013). The modern energy crisis of the world and weakening atmosphere have stimulated the fast improvement of new materials and structures such as composite materials and sandwich structures (Besant et al. 2001). Sandwich composite structures are widely used in aerospace, spacecraft, naval, marine vehicles, automobiles and other light weight structures due to their high stiffness, strength and energy absorption capacity. Sandwich structures are used not only to reduce the weight and cost but also to increase the structural performance. Typical sandwich composite is composed of two thin and strong face sheets separated from a lightweight core. They have distinct properties such as high specific modulus, lightness, strength and low coefficient of thermal expansion. Moreover, due to their design flexibility and light weight features, sandwich composites are used more in advanced aircraft components and marine structure (Meo et al. 2005). In the midst of best favorable composite structures, due to their attractive characteristics such as massive weight reduction, capability of energy absorption and power resistance, the honeycomb core sandwich panels, particularly reinforced with composite structure, have been broadly utilized. Honeycomb sandwich structure is one of the dominant structures of the sandwich composite. The method of using honeycomb core between two faces
