Preparation and mechanical properties of carbon fiber composites for sports equipment
To improve the strength and mechanical properties of sports equipment related materials,the preparation method and mechanical properties of carbon fiber composite materials for sports equipment are studied.Using con-centrated nitric acid to modify carbon fibers and SiO2 to modify epoxy resin,a carbon fiber composite material was prepared by mixing the two materials.By conducting experiments to analyze the effects of carbon fiber dosage,pre-treatment temperature,and duration on the strength of composite materials,testing the use of SiO2 and its impact on the mechanical properties of composite materials,and analyzing the impact of polyamide dosage on the bending strength of the composite material.The experimental results show that when the carbon fiber content is 7％by mass,the pre-treatment time is 5 hours,and the treatment temperature is 65 ℃,the mechanical properties such as tensile strength of the composite material are relatively ideal;When SiO2 is used as a modifier and the dosage is 4％by mass,the mechanical properties of the composite material are better;When the amount of polyamide is 2.0％,it can improve the bending strength of the tested material..
