Abstract

The invention provides a composite material which comprises raw materials of hot melting bonding fibers and bonded fibers. The composite material can meet the requirements on shock resistance, air permeability, weight and shaping performance of a sports protective tool. The invention also provides the sports protective tool made of the composite material by mould pressing and a preparation method of the sports protective tool. The sports protective tool has air permeability, thereby overcoming the defects of poor air permeability, poor environmental protection and unable considerations of both impact absorption and impact diffusion.

Description

technical field [0001] The invention relates to a sports protective gear, in particular to a breathable sports protective gear for motorcyclists made of fiber laminates and a manufacturing method of the protective gear. Background technique [0002] With the increasing popularity of sports and the popularity of motorcycles, more and more attention has been paid to the protection of shoulders, elbows, chest, back and ankles of motorcyclists, cyclists, hockey players, etc. For this reason, it has been stipulated in the relevant sports rules that the athletes and riders of this type of sports must wear appropriate protective gear in advance to reduce the damage caused by external impacts to the athletes, so as to reduce the unnecessary injury chances of the athletes and protect the athletes' health. Safety. [0003] There are many kinds of protective gear products, which can be basically divided into three types according to the different materials used: knitted, ribbon and ru...
