Protective equipment
Composite materials have become the core material of modern protective equipment due to their high strength, lightweight, impact resistance, and corrosion resistance, and are widely used in military, firefighting, medical, industrial, and other fields. The following are the main applications and technological advantages of composite materials in protective equipment.
1. Mountaineering and hiking equipment
Bulletproof vest&bulletproof plug
Weight is only 2-4kg (traditional steel bulletproof vests weigh 6kg+)
Multi layer structure absorbs impact energy and reduces blunt injuries
Material combination:
Kevlar+Ultra High Molecular Weight Polyethylene (UHMWPE) → Lightweight (70% lighter than steel)
Carbon fiber/ceramic composite armor → used for high-level protection (can withstand rifle bullets)
Bulletproof helmet
Strong wind resistance and not easily deformed
Weight only 200-400g (traditional aluminum bracket 500g+)
Type of material | Weight (g) | Ballistic Resistance (NIJ Standard) |
Steel helmet | 1500+ | Type IIIA |
Kevlar helmet | 1000-1300 | Type IIIA |
Carbon fiber composite helmet | 800-1000 | IIIA+ |
2. Industrial safety protection
Anti cutting gloves
Material Science:
HPPE (High Strength Polyethylene) fiber → Cutting resistance grade EN388 Level 5
Kevlar+stainless steel wire mixed weaving → balancing flexibility and protection
High temperature and fire-resistant clothing
Material Science:
Aramid (Nomex)+carbon fiber coating → Temperature resistant 800 ° C short-term contact
Pre oxidized PAN fiber → Long term high-temperature resistance to 300 ° C
3. Medical protective equipment
Anti stab and anti-bacterial surgical gown
Material technology:
Ultra fine glass fiber+PTFE membrane → anti blood permeation
Graphene coating → Antibacterial rate>99%
Radiation protective clothing
Composite material scheme:
Tungsten powder/carbon fiber hybrid layer → Lightweight X-ray shielding (50% lighter than lead)
Boron polyethylene → neutron radiation protection
4. Sports and Civil Protection
Extreme sports protective gear
Material application:
Carbon fiber+foam composite → motorcycle riding knee pad (only 200g)
D3O smart material → instantly hardens upon impact (ski armor)
riot gear
Innovation in Composite Materials:
Carbon fiber shield → weighs only 1.5kg (traditional steel shield 4kg)
Transparent polycarbonate+fiberglass reinforcement → Anti smashing police face mask
Composite materials allow protection to exceed its limits!
Lighter, stronger, and smarter
Breakthroughs have been made in three dimensions, which will be more widely applied in the fields of individual equipment, emergency rescue, medical protection, etc. in the future, redefining safety protection standards.
