What is Polymer Composites
Polymer composites are composite systems consisting of two or more materials with different properties, one of which is usually a polymer as a matrix and one or more of which are reinforcements.
Polymer composites fall into three main categories: fibre-reinforced composites, particle-reinforced composites and whisker-reinforced composites. The characteristics of these materials include light weight and high strength, good chemical stability, excellent electrical and thermal properties, and a high degree of designability.

The focus of this editorial is on epoxy resin composites, which are widely used in the field of composites due to their excellent physical and chemical properties.
Aerospace - for the manufacture of aircraft components, e.g. Boeing 777X uses epoxy composites in wing and fuselage structures.
Automotive - for lightweight components, e.g. BASF uses epoxy composites for body panels.
Perfect partner
Composite materials are widely used in many fields such as construction and aerospace. However, the synthetic fibres traditionally used suffer from the problem of being difficult to biodegrade, leading to environmental pollution. Therefore, the search for alternatives has become the focus of research.
Based on research articles written by Khalid Mohammad, Rozli Zulkifli, Mohammad Fazal Mat Tahir, Its experiments were carried out using different weight ratios (9%, 13% and 18%) of bamboo fibres filled with epoxy resin, and the effects of three different curing temperatures (T26°C, T38°C and T50°C) on the mechanical properties of the composites were investigated.
The particle size of the bamboo fibres was also adjusted to assess its effect on material properties. At the same time take the composite material tensile test, flexural test, impact test for testing, and strive to get accurate data results.
1. Tensile test
Using a universal testing machine , the tensile stress and Young's modulus parameters of the composites were measured at three different curing temperatures: T26℃, T38℃, and T50 °C. It was observed that at a curing temperature of T26 °C, the bamboo fiber/epoxy composites' tensile strength and Young's modulus improved to 41.6 MPa and 2.84 GPa, respectively, for particle size 0.52 μm at 13 % weight loading.
The tensile strength of the bamboo fibres decreased as the curing temperature increased.The samples prepared at T26°C showed better tensile properties than those prepared at T38°C and T50°C.
2. Flexural test
The bamboo fiber composites' flexural stress and flexural modulus were determined in compliance with ASTM D790. The composites were measured at room temperature T26℃. Every BFRC specimen was engineered to maintain consistency. Five samples were evaluated in each instance, and the average results were determined.
Flexural strength for bamboo-reinforced polymer composite increases with increasing fiber loading before decreasing. The sample with 1.5 μm particle size and 13 wt% might exhibit better flexural strength.
3. Impact test
The impact strength was determined using an Izod impact tester. In each case, 5 samples were tested and the average values were calculated.
compares the impact strengths of various combinations of bamboo fiber-reinforced polymer composites. The impact-tested load of 5593 J can be held by the 18 % bamboo fiber and epoxy resin polymer composites , which outperforms the other composite combinations.
4. Conclusions
(1) Epoxy-based composite materials reinforced with bamboo fibers were successfully fabricated. The increased adherence of the bamboo fibers to the epoxy resin led to this improvement.
(2) In tensile testing, it was discovered that a weight loading of 13 % at particle size 0.52 μm at T26 °C produced the greatest mechanical performance for bamboo composites. Nevertheless, it was discovered that when the samples were evaluated at T26 °C, epoxy composites reinforced with bamboo fibers developed more tensile strength than when the temperature was higher. The greatest tensile strength of 41.6 MPa for bamboo fibers was recorded at T26℃, T38℃, and T50 °C. The results showed that when temperatures increased, bamboo fiber's tensile strength decreased.
(3) As the particle size of bamboo fiber/epoxy composites increased, The flexural characteristics of the materials improved as well. At 1.5 μm particle size, the maximum flexural strength and modulus were discovered.
(4) At 18 wt% loading and 1.5 μm particle size, the composites with bamboo particles and epoxy showed a maximum impact strength of 5593 J/m2
