Composite materials, in simple terms, are materials that have a multi-phase system composed of reinforcing materials and matrix materials. Composite materials are divided into two types, namely synthetic composite materials and natural composite materials. Wood is a natural composite material consisting of a reinforcement and a matrix. The wood of the matoa tree (Pometia vinnata) is known for its good mechanical strength. The comparison of compressive mechanical strength in this study was conducted on matoa wood and ironwood tree wood (eusideroxylon zwageri). This was performed as supporting data in the discussion of natural composite materials of matoa tree wood as the foundation for environmentally friendly house piles. The results obtained were matoa wood and ironwood, respectively A1 = 6.07e^(-07) MPa, A2 = 1.11e^(-06) MPa, and A3 = 2.09e^(-06) MPa and B1 = 1.17e ^(-06) MPa, B2 = 2.13e^(-06) MPa, and B3 = 4.02e^(-06) MPa. These results indicated that the resistance to mechanical compression test of ironwood tree was greater than matoa tree. However, when it was seen based on the perspective of the impact on the environment, Matoa tree has environmentally friendly properties that are effective and efficient. This is supported by the nature of the matoa tree which is easy to cultivate and its roots do not damage other plants.

Composite material is a material that has a multi-phase system composed of reinforcing materials and matrix materials. Causes the composite materials to have advantages in various ways such as low density, high mechanical properties, performance comparable to metal, corrosion resistance, and easy to fabricate. In the marine and fisheries industry, composite materials made from fiber reinforcement, especially fiberglass, have proven to be very special and popular in boat construction because they have the advantage of being chemically inert (both applied in general and marine environments), light, strong, easy to print, and price competitiveness. Thus in this study, tensile and impact methods were used to determine the mechanical properties of fiberglass polymer composite materials. Each test is carried out on variations in the amount of fiberglass laminate CSM 300, CSM 450 and WR 600 and variations in weight percentage 99.5% -0.5%, 99% -1%, 98.5% -1, 5%, 98% -2% and 97.5%-2.5% have been used. The results showed that the greater the number of laminates, the greater the impact strength, which was 413,712 MPa, and the more the percentage of hardener, the greater the impact strength, which was 416,487 MPa. The results showed that the more laminate the tensile strength increased, which was 87.054 MPa, and the more the percentage of hardener, the lower the tensile strength, which was 73.921 MPa.

In recent years, natural composite materials have replaced many conventional ones, such as metals and synthetic resin composites in many applications. This is due to the advantage of hybrid natural composite over the conventional materials. The natural composites are made up of both reinforcement and matrix materials which are obtained by the natural resources. Natural fibers reinforcement are strong, light weight, renewable, cheap, completely or partially recyclable, and biodegradable. In this work sisal and banana fibers have been used as the main reinforcing materials to increase the effectiveness of natural fibers. Cashew nut shell liquid (CNSL) resin is a natural resin that can be obtained from cashew nut. CNSL is essentially a mixture of phenol extracted from the shell of the cashew nut and is a good natural alternative to chemically derived phenol.

In this study, the problem of finding the shape of the strongest column which has the largest fundamental buckling load with equal length and volume for the clamped–clamped ends was purposed. It was also proved that the solutions of Tadjbakhsk & Keller (1962) and Olhoff & Rasmussen (1977)-Masur (1984) were not optimum for columns with clamped ends. Then, true solution was obtained from Masur's analytical bimodal solution for clamped-clamped case by considering the crushing criteria. To test the accuracy of new optimized columns with clamped ends, both experimental and numerical studies were carried out. In this study, natural composite materials such as cedar and oak with variable circular cross-sections were used. Results of the optimum model proposed in this study were in agreement with results obtained by experimental data and numerical results.
